People should choose what kind of photographic lens?
A variety of camera lenses, although the figures can be used for photography, but, strictly speaking, people should have the following lens photography some of selectivity:
1, imaging
People photography lens image quality, it is necessary to end like the clear, but also have some soft effect. Because people are generally the performance of face-based photography, the camera image quality should be able to achieve levels of rich, realistic texture, detail absolutely shattered, skin moisture requirements.
2, the focal length
Generally equipped with a standard lens on both cameras, the war film camera focal length of the frame similar to the length of the diagonal. This lens, it should only take pictures of people the whole body or large bust. If the half-length figure or head for shooting close-up as too close, image perspective distortion is often caused by people, and some shots if the provisions in the near distance of the most recent photo shoot, can not be clustered into clear focus. So, head shot or close-up characters, then use the focus or telephoto lens, its focal length lens usually takes 1-2 times over the standard to 135 cameras, for example, the lens focal length to be as high as in the 105 meters,Acer Aspire 5536 battery so that the camera and People distance, more than 1.5 meters can be maintained, both to make the focus clear, but also to avoid a big nose and ears and small deformation. Small photos of the indoor shooting, if you encounter the lack of deterioration of the situation, we need to use short focal length lens (ie wide-angle lens), but prone to near the far smaller and slightly deformed characters on both sides of the defect.
3, diameter
Half-length figures and head close-up shooting, to a large effective aperture of the lens is appropriate to make the subject clear and the background slightly blurred, and enhance a sense of near and far space perspective, thus highlighting the subject. In addition, the effective lens aperture large, slightly darker in the light of the circumstances but no flash, shooting people, still use a faster shutter speed.
Fifth, tourism pictures of people, what to bring photographic equipment and accessories?
1, photographic equipment
Travel pictures of people want to carry photographic equipment, generally light and appropriate. Typically, the film tour commemorative photo, holding an ordinary camera, a small 135 or "fool" the camera, can be applied.dell Inspiron 1525 battery If the person preparing to further engage in photography, such as shooting some of the local customs, etc., it is best to carry a 135 interchangeable lens single-lens reflex camera, and coupled with a 28-80 mm zoom lens, both for photography needs to adapt to , but also reduce the equipment volume; Alternatively, you can use the camera, while the original standard lens, and then configure the 24-28 mm lens and 85-105 mm wide-angle lens, one each in order to choose. If you need the same time people of color and black and white photography, it is best to have two aircraft, each equipped with color and black and white film, alternating (if carrying the adjustable back 120 single-lens reflex camera, you only need one can be applied.)
2, annex
No matter what portable camera, lens hood and II are advised to keep a yellow filter. If conditions permit, it is best used to bring color and black and white photography of various main filter (including the UV mirror, sky mirror, polarizer, etc.) as well as black and white photography of yellow, red and green filters. Also carrying a small electronic flash or self-reflective panels for auxiliary lighting. To be able to maintain the camera and lens clean, to bring the lens paper and lens brush, if even with a good blow up balloons. Travel pictures of people, due to the hand-held shooting angle can be more free to choose, so a tripod with a low frequency, do not have to carry; but if can take to prepare for contingencies, and of course better. In addition, should made available for a pocket notebook, a brief record of shooting situations, including the date, weather, time, situation, characters and the use of aperture, shutter speed, etc., in order to accumulate the data, at any time refer to continually improve their standards.
What additional black and white figure photography often mirror?
Black and white figure photography, the camera lens before the commonly used additional mirrors, including the nature of change and change shade shadow imaging Results of two series. Example of the former variety of colored filters, air filters, UV microscopy and sky mirror and so on, which for example, soft mirror, halo of the lens and close-up lens, etc.,Acer Aspire 5741 battery are as follows:
(A), commonly used to change the nature of additional lens shade
1, a variety of colored filters
Such filter is optical glass with color and refined, yellow, green, red, orange, blue and other, were named in various colors. Its role is to prevent or reduce unwanted shade, relative to the required increase in the amount of light shade of the pass, to change the color and feel Gan Guangpian. Black and white figure photography, yellow filter is most commonly used, for example, in the case of blue sky, shooting outdoors people, once plus, you can absorb some blue light, making it less sensitive blue film, which appears in the photo the sky darker, and the effect of clouds was outstanding; otherwise, will be mixed to the same color blue and white. Into the white sky, dull. Yellow filters can enhance the level of character texture and delicate vivid color performance. It also has a transmission range, the characteristics of low light resistance, therefore, added with yellow filter, only half of file to open the aperture, while the addition of the yellow filter, but also just opened freshman profile aperture.
2, sky filter
This is half of the pale yellow or light gray, colorless translucent add a mirror. As part of its edges colored by the deep to shallow, gradually over to the colorless, transparent, therefore, also known as the gradient filter. Its role is to adjust the contrast between sky and ground. Specifically, the colored part of the purple blue of the sky can absorb or reduce the intensity of light the sky, the sky part of the limited amount of exposure in the film, so that the ground segment in the film more exposure. Use, the colored part should be facing up, no additional exposure. When photographing people in backlight, plus air filter, the effect is even better.Acer Aspire 5738Z battery
3, UV and Skylight lens
Most are colorless UV microscope, there are slightly yellowish; sky mirror is close to colorless or slightly reddish. Their main function is absorption of ultraviolet radiation in the atmosphere. UV effects on alpine photography more serious, and often hinder the clarity of the image. UV plus or sky mirror mirror, you can eliminate the influence of UV on the Gan Guangpian to improve image clarity, especially for distant scenery is more effective. Since UV and Skylight lens is a colorless or near colorless, no need to increase exposure for photography under any circumstances and no side effects, therefore, often added wear on the lens to protect the lens.
(B), change the video used an additional lens imaging Results
1, soft mirror
Soft lens effect, is to be part of the light through the lens refraction, so the photographer can maintain a certain image clarity, while a softer tone contrasts but also natural. The construction of soft lens in various forms, usually in a transparent glass, have the density of different circular ripples, or is the use of nylon or other fibers are woven into the mesh, so as to achieve the purpose of refraction separate incident. Add to wear soft mirror, close-up photo shoot women and children, can be soft and pleasing effect of images.
2, the halo of the lens
Halo shape of the mirror structure, is to open a hole between the glass lens, was surrounded by sand-like. Hollow in between, plus worn on the front of the camera will not affect the main image is focused. When photographing people, will face arranged in a circular hole location, you can get the normal resolution, and face around the outside of the image, due to lens-like effect on the sand, then show the effect of hazy halo. Add pictures of people wearing a halo of lens to use single-lens reflex camera is appropriate, because the photographer by the camera viewfinder, direct observation of the situation to the image halo.
3, Close-up Lens
Half-length mirror, also known as close-up lens is a convex positive lens, plus wearing, you can shorten the lens focal length, but also to shorten the distance of a recent photograph, so that images of people to expand, take full advantage of Gan Guangpian area. When shooting, the general need to increase exposure, but to use a small aperture in order to increase the dark deep corners to prevent false negatives loose. Practice in photography, taking pictures of people close-up close-up lens is not appropriate, because the close proximity of photography, Acer Aspire 5920 batteryeasy deformation defects. In addition to the commonly used additional mirrors, there are many shadow mirror, star mirror, mirror in the ash and other special effects add a mirror, by the addition of, the first two can be respectively different radial multi-light image and the effect of the latter which can help reduce the amount of light rays through the role.

Initial purchase of laptops for each consumer will experience two difficult problems, one is how to choose, and the other is how to choose a good test machine, while the focus of this article is to teach you how to smoothly through the testing machine this link .
In order to avoid the development of machines to buy profiteers, pathogenesis, testing machine of this aspect is particularly important, although the three bags of pledges return 15 days replacement 3 days, even to enjoy the same Warranty Services will bring their own a lot of unnecessary trouble, not to mention wait until after a period of three bags found the problem.
As notebook computers in the computer market to buy time is often more limited, so we can not on a laptop computer to conduct a comprehensive test, I personally think that when buying laptops should focus on the appearance of the machine, serial number, screen, drive, keyboard, ports, etc. to check, while others can be based on the actual situation.
First, optimistic about the appearance of the re-start
If you buy is licensed in most cases, the machine seals the box should be intact,Nikon MB-D10 battery grip if a proposed business has opened a sealed box while the machine may be used for display or have been picked off on a buyer machine, you have every reason to request exchange.
General box in each laptop will have a detailed packing list, then you can control the documents and information take a look at all the parts are complete, such as CD-ROM, a total of a few, a total of several instructions, What are the accessories, in short, like a lot to do. In addition to look at the bottom of the machine is affixed with genuine Microsoft operating system's serial number sticker, or a random valuable genuine operating systems becomes waste.
Then please do not power on, you should carefully check the machine out the appearance of the machine,Dell Inspiron 6000 Adapter are there plans, knock, touched the mark, especially in the corners and bottom of the machine rubber pads for wear; fixed screws have been twisted flowers; Also note that the surface of the machine there is an obvious use of signs, such as fingerprints, grease, etc., because the surface coating as many features of the machine once a trace is difficult to clean. You can then open the screen repeatedly opening and closing times to see if there was loose, and look carefully to see if there are glossy keyboard, especially the letter keys and the spacebar. Finally, check the PC card slot replacement baffle plate and the interface for any damage or loss, the appearance of the test that is down to this end.
Second, carefully check the serial number
Before the formal start of the serial number we have to check boxes, and the BIOS information in the bottom of the machine serial number are consistent with the formal adoption be considered. How to enter the BIOS settings as different models may be, some models such as Toshiba, does not boot into BIOS functions check only the bottom of the box and the machine serial number.
Storm coming! A sultry summer, suddenly, the sky darkened, thunder, lightning glare ...... this time you really thought about, get out your camera, captured this memorable moment?
You might think the Lightning captured the sharp need for super-quick response capability. No, you're wrong. You just need to stand at the right time right place on the line. If you take a few minutes watching the sky, you will find that lightning is in the air moving, but it intermittently with missing trends. You can not accurately calculate a bunch of lightning appears under the time and place, but you can predict in a few minutes to a regional lightning may occur, in particular, is always accompanied by thunder and lightning. This is the key. If you set the camera has a long shutter speed, you will record the ongoing flow of lightning. Sharp lightning may be only a few seconds there, but by a few minutes of the shooting,Dell Inspiron 1300 Adapter you will always have a surprising grasp and lightning effects.
First, the tools you should be prepared to
You need a camera with long exposure settings. Pretty good rate of 30 seconds. But if another shorter, you get the odd chance of lightning would be reduced. You can manually set the shutter speed, but if the camera has an automatic setting also, you have to turn off the automatic flash.
You also need a tripod to keep the camera stable. Recommend the use of a wide range of values of the camera lens, so that the air you captured a wider range of areas, there will be more opportunities to photograph lightning. Ideally taken in the evening. Of course, if lightning occurs during the day, do not miss. Only during the day, you do not want to make the sky is overexposed, and want a long shutter speed, so the opportunity to shoot lightning will be very limited.
Second, to begin shooting
Then we put the camera tripod, aim it appears you think the lightning area. The camera is set to the smallest possible aperture: f/16 or f/22. If your camera is fully automatic, there is no over-exposure control, then you only need to make sure the flash is closed. We can also a detailed description of the camera, to check the ability of its long exposure. Raytheon equipment like a good time, often give us direction for the next bunch of lightning occurred. Between several minutes of thunder, lightning will always be there. After the current burst of thunder, lightning will come much faster.Dell Inspiron 1720 Adapter It flashed faster. This is a good indicator: Lightning How far away from us. In general, the 15-second interval will imply Lightning 3 miles away from us. This can help us decide what press the shutter. Here, control the shutter using a cable would be better, so will not cause shaking.
Hold down the shutter, keep your fingers do not move, until the lightning occurred in the target area. If your camera has a separate viewfinder, you will be able to see whether lightning is photographed. Here, the use of digital cameras have an advantage is that you can preview the captured images, if not shoot, then delete it and re-shoot. But if it is used SLR cameras, it does not. Because it is progressive lenses, you can only pray that lightning was captured.
If your camera has a B setting, you can put the shutter open. Cover the lens with a card. When you think that lightning will occur, the card is removed, photographed and then can put it back. Finally repeat, time to grasp is the most critical. You need a total exposure time of 30 seconds, so you may be in a photograph in the film several times lightning. I have photographed over two beams of lightning. We can see from the figure.
Third, where the shooting lightning
There is also a most important issue is security. Because we are shooting outdoors lightning is very dangerous. A storm on the one hand, on the other hand may face lightning attacks. Therefore, we are likely to wonder whether the shot at home safely. RIGHT! From a scientific point of view, shooting lightning under a tree is more dangerous. Therefore, we the best in the house, car or large building shooting. If it is within the car, you should open the windows. Indoors, you should stay away from windows, water, electrical appliances, avoid using the telephone. Try to put the camera placed near the window,Dell Inspiron 1750 Adapter use the cable remote control camera shutter. If you can see the lightning through the open window area there, so will not appear reflective glass or other defects: such as lower quality, the camera focusing problems and so on. If you are shooting through a closed window, then the light bulb to turn off the house, if needed, use the flashlight to light. At the same time adjusting the camera's auto focus to manal focus or infinity mode (if any).
We can also select a window, can clearly see the lighting of the mobile trend. Of course, we can do in a car. This is even more dangerous point. Particular care.
If you think outside of shooting, just like this picture I shot the same (this can be very stupid, but adventurous and gone for the arts, but also very worthwhile.) We can not rain before the storm is about to start, photographed for the first bunch of lightning. If you are shooting in the rain, we must pay attention to protect the camera. Therefore, it is best to use a special kit, such as plastic wrap with a camera. Always remember, stay away from trees!

First, the documentary and artistic:
The works of many sports photographers the full show, a documentary photo to a sporting event can be completely artistically creative way to shoot, but an artistic documentary sports photos is not necessarily without value. Newspapers in general have a photo documentary requirements, to reflect the game's defining moment. Need to introduce the reader is not the photo shooting skills, but the public in a matter of concern at the time, such as unexpected scores, Nade's defeat, the rise of rookie, and the celebration ceremonies. The art of photography magazines or other publications require photo composition and beautiful, expressive content, with high artistic value and enduring.
Second, the amateur photographer's Advantages:
Amateur photographers is that the biggest advantage of the absence of mental burden. He does not record the action superstar. He could easily Seek shooting scene, choose the subject. For the art of sports photography, the game's name is irrelevant, it is important gesture photo and photography athlete's performance capacity. A small-game pictures of beautiful, no doubt a big game than the poor picture much better.
Third, the photographer's training:
First, research. To take a sport which, we should have full access to this sport, to understand its characteristics. Only the most exciting way to foresee what the scene will appear when and how to seize the opportunity to capture vivid scenes.
Second, sophisticated techniques. Physical exercise is characterized by rapid change. This requires the photographer to be agile, skilled operation, in a very short period of time adjusted the aperture, distance, and shoot. This ability is only through a lot of practice to master.
Fourth, the key to success:
For a successful work, it is important to arouse emotional responses. Whether a sports photo praised by others, mainly how the technology is not the superb shooting, but rather the information content of pictures. The greater the amount of information conveyed by photographs, the higher the quality of information (ie shooting more with the way the original), photos of the appeal will be. However, the information does not necessarily talking about here refers to a documentary to a sporting event itself, the situation is any other information. For example, the speed of movement performance, the audience's emotions, facial expressions of athletes, and the shares were elated, and so an air of dejected losers. Static and dynamic, beautiful, innovative, detail features, space and color can also have a high information content, if used properly, for photographs to convey the content.HP G60 battery
Photos of the value and appeal of the persistence depends on two factors: the "what" (theme) and "how" (composition). The combination of the two decisions picture quality. "What" mainly by personal interest and asked him who the request of the decision. "How," mainly by the personal style and preferences of decision.
Fifth, several special methods:
Since sports is changing fast and moves to its characteristics, the photographer should be to show these features in the photo. Depending on the circumstances he must be able to use some special shooting methods.
Action "freezing": This is the most commonly used method. Re-emerged in a clear and true to his face and body contour, people to see the result of too fast and could not see the details at the time. The following table lists the minimum in different situations shutter speed:
In the case of poor light, even if a large aperture opening can not obtain the required shutter speed. At this time an action should be the climax, when close to completion, that action tends to stagnate in the past to change direction to capture the moment.
Following the shooting: the direction of motion along the target, move the camera steady, rich in the target position in the viewfinder is always the same, and in the decision to move while pressing the door. This method can be used to take the road in the sprint athletes, riders and drivers. Its effect is to clear the image of athletes, and the background blurred. Advantage is to avoid damage to the busy background images at the same time, the background to bring out the fuzzy action fast. Shutter speed to follow the law, usually 1/15-1/60 seconds. In the case of not sure, you can use the same target shooting a few different shutter speeds for selection.
Blur effect: a lower shutter speed shooting fast action, hazy images will appear blurred outline. In this way, not only can produce movement, but also show that the action fast. Level should be moderate, however vague, too vague and would not identify the body, not misleading picture is fuzzy defective. Try different shutter speeds can be compared. Reduce the shutter speed, aperture go far too high, the town can be gray filter, polarizer,Dell XPS M1330 battery or the red filter (color film can not be used.) But the use of filters will cause the town changes color and tone.
Zoom: press the shutter head while promoting zoom lens, the lens focal length by a long short. This method can slow the action a "speed up" effect, very in the drama. The outline of the main body along the diagonal direction from the center of the screen extended to the surrounding, as if to explode toward the camera. This effect can only be obtained with a lower shutter speed (1 / 15 sec - 1 sec), so it is best to use a tripod. While you press the shutter, the camera under the direction of movement up, down or to the case to move quickly, but also to get a similar effect.
VI Exposure:
Exposure measurement object is of the main part of the photo, that is, athletes. But the photographer is often difficult to close to the athletes, when used near other people or their own hand instead.
If you use a camera with automatic exposure device, in some cases it is best not to use automatic exposure system. Because as the player changes the location of the background is also changing the screen in the background occupies a large part, the automatic exposure device measured readings to athletes does not mean that the brightness of the main results of the exposure will not be allowed.
VII equipment:
Sports Photography generally use a faster film speed, usually to DIN 27 degrees (ASA400) the film is ideal. In the dim light, in particular circumstances, may also increase sensitivity shooting, during development, "sensitization." But this film will make larger particles.
In addition to standard lens and wide-angle lens outside, long focal length lens is very useful. It is not only the distant scenery closer to the main full screen, and because of its small range of depth of field, able to separate the subject and background clutter, make the subject more prominent, positive before and after shooting athletes reduce the size between the imaging difference. Sports Photos taken with a zoom lens is also very good, because it can continuously change the focal length, able to adapt to a variety of shooting requirements. Sports photography accessories, the most important electric roller disc devices. It allows you to continuously take some photos in a second, so you can focus entirely on target shooting, will not miss the opportunity to roll film.
Sports photography is dedicated viewfinder prism a useful accessories. It consists of an increase in the eyepiece prism and a rectangular form. Photography can very easily in six cm from the viewfinder to the eye, while the audience observing the situation over the camera.

Compared with traditional cameras, digital cameras when shooting night by the technical limitations can not be second exposure, the dark details of the performance to be relatively worse, in order to perfect the performance of the scene shot on a series of setbacks have cost . For friends new to digital photography, how to use digital cameras to shoot the perfect night?
The more words the night more beautiful city for the night is really just the right terms, the city that never sleeps with rich colors, bright lights, this night's shooting has become a subject of photography. Although the digital camera difficult night, but we can rely on timely prosecution LCD screen exposure situation, by adjusting the color temperature can be more satisfied with the color.
1. Night shooting also pay attention to the location
Night shooting also pay attention to location choice? The answer is definitely yes! Dazzling lights at night can be said is a prerequisite for night shooting, no lights or light rare objects can not be shown, or performance is not clear. With enough light, not only can make an object present level, can make the picture brighter and clearer. Therefore, select the appropriate location is very important.
2. Night shooting equipment, some stress
While any digital camera can shoot a night scene, but the equipment will ultimately determine the difference between the effect of the film. Must first have an offer aperture priority, shutter priority functions, exposure compensation function of the digital camera. Around the film because the effect of light interference and even easier to spot the formation of a digital camera's lens hood you can easily solve the above problem, if no hood would also be temporary with a large book or other objects that block.
In addition, most of the time shooting night take a long time exposure, hand-held shooting is basically impossible, so need to use a tripod to a fixed camera. If the camera shutter release cable or remote control with the words of the film easier to shoot a clear (if not both, you can try to use the camera's self-timer function), like the Olympus 5050 were equipped with such a small annex, in the night shooting in will be of great use. For starters, if there is not the time to select the side of the road can be adapted to local conditions half the height of railings or walls used for fixed cameras. When there is no relying on something, you can try to use the high value and large aperture for light-sensitive handheld shooting.
3. Night shoot combat skills
Many high-end digital cameras offer P (auto), A (aperture priority), S (shutter priority),HP ProBook 4510S battery M (manual) exposure shooting modes, in addition to most of the digital camera scene modes are provided, the most common The model is two night mode and macro mode. For starters, use the night mode to shoot digital camera is the most convenient and effective method. If your camera does not provide a scene shooting modes, you need to pay attention when shooting the following aspects:
4. Aperture and shutter
Under normal circumstances, in addition to special needs, we like to use a smaller aperture (F8 to about 11 or so) to increase the exposure time. Smaller aperture can make the same vision and clear and detailed close-range images, in particular, a store window display of neon signs can be clearly, otherwise it will form into a ball of light neon signs, it looks blurred. Interestingly, as long as the exposure time long enough, the road pedestrians will not appear in the picture (due to people moving, in the long exposure, the human figure will become obvious), but the car is driving on the road will form a dynasty in the Shadow (aperture F7, 12 seconds long exposure, ISO value of 160). If you want the night to shoot people in the main, then have to use a larger aperture (F5.6 or so, much will bokeh) or the use of high sensitivity (ISO) to increase the shutter speed.
5. Accurate metering
I believe most people find difficult shooting night the place is metering out. When long-distance shooting night, the black sky will affect the camera's metering readings, so that over-exposure photos taken. In addition, if the shooting affected by spotlights or other bright light, to some extent pictures will be underexposed.Most digital cameras have a wide range of metering modes, and therefore should correspond to the actual situation of the metering mode selection. Because different metering mode will directly affect the accuracy of the photo exposure. In order to capture the charming night, it is best to do when shooting twelve appropriate exposure compensation adjustment. If you use the shutter priority or aperture priority mode when shooting, very often the phenomenon of over-exposure can also occur, then how to adjust the exposure compensation value to a lot of people have tried the.
6. How to use the white balance
Select a different white balance, will directly affect the expression of the photo and the colors the mood. Generally do not choose automatic white balance, this will affect the color of the light inherent to make sense out specific color temperature. If the shooting city night, then in general we will use the Tungsten (incandescent light) white balance, white balance as close to light by this effect. Of course, this is not absolute, depending on the environment.
7. Night of the focus
As an ordinary digital camera focus sensor with low contrast and low brightness of the scene is difficult to accurately focus, so the focus during the night shooting, try to sharpen the focus will be on bright scenes, aligning the focus of the composition and then lock the focus . Of course, you can switch to manual focus, the use of LCD to view the focusing effect. Rough estimate of the distance between the scene and the camera, and then the numerical LCD display, select the appropriate focal length.
Apart from the above aspects, the night in the shooting is best to avoid using the flash when doing so would undermine the atmosphere, and the general shooting randomly flash in the night but there is no much effect. Good night you want to shoot the film, in addition to lots of pictures, we should also look at other people shoot the film, learn film techniques and methods.

Apart from the above aspects, the night in the shooting is best to avoid using the flash when doing so would undermine the atmosphere, and the general shooting randomly flash in the night but there is no much effect. Good night you want to shoot the film, in addition to lots of pictures, we should also look at other people shoot the film, learn film techniques and methods.

Compared with traditional cameras, digital cameras when shooting night by the technical limitations can not be second exposure, the dark details of the performance to be relatively worse, in order to perfect the performance of the scene shot on a series of setbacks have cost . For friends new to digital photography, how to use digital cameras to shoot the perfect night?
The more words the night more beautiful city for the night is really just the right terms, the city that never sleeps with rich colors, bright lights, this night's shooting has become a subject of photography. Although the digital camera difficult night, but we can rely on timely prosecution LCD screen exposure situation, by adjusting the color temperature can be more satisfied with the color.
1. Night shooting also pay attention to the location
Night shooting also pay attention to location choice? The answer is definitely yes! Dazzling lights at night can be said is a prerequisite for night shooting, no lights or light rare objects can not be shown, or performance is not clear. With enough light, not only can make an object present level, can make the picture brighter and clearer. Therefore, select the appropriate location is very important.
2. Night shooting equipment, some stress
While any digital camera can shoot a night scene, but the equipment will ultimately determine the difference between the effect of the film. Must first have an offer aperture priority, shutter priority functions, exposure compensation function of the digital camera. Around the film because the effect of light interference and even easier to spot the formation of a digital camera's lens hood you can easily solve the above problem, if no hood would also be temporary with a large book or other objects that block.
In addition, most of the time shooting night take a long time exposure, hand-held shooting is basically impossible, so need to use a tripod to a fixed camera.HP Mini 110 battery If the camera shutter release cable or remote control with the words of the film easier to shoot a clear (if not both, you can try to use the camera's self-timer function), like the Olympus 5050 were equipped with such a small annex, in the night shooting in will be of great use. For starters, if there is not the time to select the side of the road can be adapted to local conditions half the height of railings or walls used for fixed cameras. When there is no relying on something, you can try to use the high value and large aperture for light-sensitive handheld shooting.
3. Night shoot combat skills
Many high-end digital cameras offer P (auto), A (aperture priority), S (shutter priority), M (manual) exposure shooting modes, in addition to most of the digital camera scene modes are provided, the most common The model is two night mode and macro mode. For starters, use the night mode to shoot digital camera is the most convenient and effective method. If your camera does not provide a scene shooting modes, you need to pay attention when shooting the following aspects:
4. Aperture and shutter
Under normal circumstances, in addition to special needs, we like to use a smaller aperture (F8 to about 11 or so) to increase the exposure time. Smaller aperture can make the same vision and clear and detailed close-range images, in particular, a store window display of neon signs can be clearly, otherwise it will form into a ball of light neon signs, it looks blurred. Interestingly, as long as the exposure time long enough, the road pedestrians will not appear in the picture (due to people moving, in the long exposure, the human figure will become obvious), but the car is driving on the road will form a dynasty in the Shadow (aperture F7, 12 seconds long exposure, ISO value of 160). If you want the night to shoot people in the main, then have to use a larger aperture (F5.6 or so, much will bokeh) or the use of high sensitivity (ISO) to increase the shutter speed.
5. Accurate metering
I believe most people find difficult shooting night the place is metering out. When long-distance shooting night, the black sky will affect the camera's metering readings, so that over-exposure photos taken. In addition, if the shooting affected by spotlights or other bright light, to some extent pictures will be underexposed.Most digital cameras have a wide range of metering modes, and therefore should correspond to the actual situation of the metering mode selection. Because different metering mode will directly affect the accuracy of the photo exposure. In order to capture the charming night, it is best to do when shooting twelve appropriate exposure compensation adjustment. If you use the shutter priority or aperture priority mode when shooting, very often the phenomenon of over-exposure can also occur, then how to adjust the exposure compensation value to a lot of people have tried the.
6. How to use the white balance
Select a different white balance, will directly affect the expression of the photo and the colors the mood. Generally do not choose automatic white balance, this will affect the color of the light inherent to make sense out specific color temperature. If the shooting city night, then in general we will use the Tungsten (incandescent light) white balance, white balance as close to light by this effect. Of course, this is not absolute, depending on the environment.
7. Night of the focus
As an ordinary digital camera focus sensor with low contrast and low brightness of the scene is difficult to accurately focus, so the focus during the night shooting, try to sharpen the focus will be on bright scenes, aligning the focus of the composition and then lock the focus . Of course, you can switch to manual focus, the use of LCD to view the focusing effect. Rough estimate of the distance between the scene and the camera, and then the numerical LCD display, select the appropriate focal length.
Apart from the above aspects, the night in the shooting is best to avoid using the flash when doing so would undermine the atmosphere, and the general shooting randomly flash in the night but there is no much effect.

1, the new energy automotive battery types
From a global perspective of the development of new energy vehicles, including its power supply lithium-ion batteries, nickel hydrogen batteries, fuel cells, lead-acid batteries, supercapacitors [2], where lead-acid batteries, super capacitors mostly in the form of an auxiliary power source appears.
A: Lead-acid batteries
Lead-acid battery has been 100 years of history, is widely used as the starting power source for internal combustion engine vehicles. It is also a mature electric vehicle batteries, it reliability, easy to get raw materials, cheap; can basically meet the specific power are the power requirements of electric vehicles. But it has two major drawbacks; one lower than the energy, mass and volume occupied too much mileage and shorter charge time; the other is that life is short, the use of high cost.
B: Ni-MH battery
Ni-MH batteries are alkaline batteries, Ni-MH battery cycle life is longer, no memory effect, but the price is higher. Its initial acquisition cost may be high, but because of its advantages of energy and life, so the actual use of its long-term cost is not high. At present foreign produce nickel-metal hydride batteries for electric car company is Ovonie, Toyota and Matsushita, a joint venture. Ovonie existing 80A ¡¤ h and 130A ¡¤ h two-cell battery, the specific energy of 75-80W ¡¤ h / kg, cycle life of more than 600 times. The batteries installed in several electric vehicles on the trial, one type of car on a single charge can travel 345km, a car of the year driving for more than 80,000 km. Because higher prices have not yet mass production.hp g60 laptop battery China has developed 55A ¡¤ h and 100A ¡¤ h cell battery, than the energy of 65 W ¡¤ h / kg, power density than nickel-metal hydride batteries 800W/kg.
C: Lithium-ion battery
Lithium ion secondary batteries as a new high voltage, high energy density rechargeable batteries, and its unique physical and electrochemical properties, a wide range of civilian and defense applications prospects. Its outstanding features are: light weight, large storage, no pollution, no memory effect, long service life. Under the weight of the same size, storage capacity of lithium batteries is 1.6 times the nickel-metal hydride batteries, nickel cadmium battery 4 times, and the current human development and utilization of only its theoretical capacity of 20% to 30% and the outlook is very bright . At the same time it is a real green battery, no pollution to the environment, is the best electric car can be applied to the battery. Beginning of the nineties from the twentieth century, the development and use of lithium-ion battery, a breakthrough has been made so far, developed a completely independent intellectual property rights of lithium-ion batteries.
D: Ni-Cd Battery
Nickel-cadmium batteries are widely used second only to lead-acid batteries, the specific energy of up to 55W ¡¤ h / kg, than the power of more than 190W/kg. Fast charge, long cycle life is more than twice the lead-acid batteries can be achieved by 2000 many times, but the price of lead-acid battery 4 to 5 times. Its initial acquisition cost may be high, but because of its advantages of energy and life, so the actual use of its long-term cost is not high. Is a "memory effect", easy as a result of poor charging and discharging the battery available capacity decreases. To be in use after about ten times for a complete charge and discharge, if you have the "memory effect" should be a continuous period of 3 to 5 times fully charge and discharge, to free memory. Addition of toxic cadmium, the use of sense to do recovery work, so as not to cause environmental cadmium pollution.
E: sodium sulfur batteries
Sodium sulfur battery advantages: one is higher than the energy. The theoretical specific energy of 760W ¡¤ h / kg, actually more than 100W ¡¤ h / kg, lead-acid battery is 3 to 4 times; the other is high current, high power discharge. The discharge current density is generally up to 200 ~ 300mA/mm2, and instantaneous time can be 3 times the release of its inherent energy; another one is the charge and discharge efficiency. As a result of the solid electrolyte, so there is no liquid electrolyte secondary battery is usually the kind of self-discharge and side effects, charge and discharge current efficiency was almost 100%. Sodium sulfur battery shortcomings, mainly its working temperature of 300 ~ 350 ¡æ, so when the battery needs some heat insulation. Severe corrosion in high temperature, battery life is shorter. Now have high-performance vacuum insulation technology, can effectively solve this problem. Stability and performance are also not ideal to use safety issues. 80 to 90 years, focusing on the development f sodium sulfur batteries abroad as a fixed occasions (such as power storage) applications, and increasingly shows its superiority. Progress in this regard the most significant Japanese companies. As the generally optimistic about the recent battery electric vehicles, has been the United States Advanced Battery Consortium (USMABC) as the medium-term development of electric car batteries, produced by the German ABB B240K Sodium sulfur battery,Canon BG-E9 battery Grip the quality of 17.5kg, storage capacity 19.2Kw ¡¤ h; than the energy of 109W ¡¤ h / kg, 1200 times the service life cycle, a loading test, the best problem-free driving for 2300km.
2 types of new energy automotive batteries advantage
February 2009, the Ministry of Finance, Ministry of Science issued a "energy-saving and new energy vehicle demonstration and extension of financial subsidies for Interim Measures," mentions the use of lead-acid batteries and nickel-metal hydride batteries, lithium-ion battery hybrid types subsidies for the vehicles, the maximum subsidy was 80,000 yuan / vehicle and 42 yuan / vehicle. The June 2010 release of subsidies for new energy vehicles in order to determine the battery capacity as the only indicator of subsidies, lead-acid battery was completely negative. Early definition of new energy vehicles, including a project lead-acid batteries, but this clearly does not include subsidies for lead-acid batteries power batteries. But also as the main nickel-metal hydride hybrid battery will also be less subsidies. Can be seen, at the policy level, the lithium-ion battery and super capacitor to benefit the largest object.
3, the new trend in energy prices car batteries
The price trend, the current electric vehicle fast charge lithium-ion battery prices in the $ 1600/kwh about ordinary lithium-ion battery prices in the $ 500/kwh, according to the current U.S. gasoline and electricity price trends, in the car's entire life cycle inside, 100km endurance of fast-charge lithium-ion battery electric vehicles to use performance rather than the cost of gasoline internal combustion engine cars 25% higher. Once the electric vehicle battery price drops to $ 200-300/kwh, electric vehicles and conventional vehicles using the cost will be considerable. According to projections, the relevant policies in the country, encouraged by 2020 the global demand for electric vehicles using lithium-ion close 50Gwh, fast-charge the battery cost is expected to decline in 2020 to $ 400-500/kwh, common battery prices could fall to $ 200-300/kwh .
New Energy Vehicle Charging Station
Car charging stations and gas stations similar to a "power" device. Is a high efficiency battery charger, you can quickly give mobile phone charging electric cars electric vehicles.
China Southern Power Grid, as energy conservation and new energy automotive applications, the demonstration pilot, Guangzhou City, the first public electric car charging stations 8 November 2010 put into operation in the Asian Games, the charging station is located in Nansha Port Expressway and Beijing-Zhuhai Expressway, between sets charging service facilities and sales offices in one, 24-hour service charge pile, built on-site purchase of electricity on-site charge and a quick passage, but also the Asian Games City "exclusive" business outlets.
China Southern Power Grid implementation of the charging station charging technology developed standards for three-phase electric cars charging power supply, technical standards, compared with another single-phase power, three-phase power output capacity per unit time is the three times, charging efficiency, spend less time. Rated power of 21 kW AC charging a single pile, for example, is full of an electric car only 3 hours, reducing the time cost of using electric vehicles. The rechargeable battery charging station is not only convenient, but also in the introduction of the second phase construction of convenience stores and other convenience facilities.
Guangzhou Power Supply Bureau, 2015, completed 61 bus charging stations, 54 public charging stations, slow Chong Chongdian pile 80110, covering the city's 12 districts and counties. Power companies will be the first test the water, leading the green energy trend.

Q: Ask the Expert, will the long-term plug laptop power supply (I believe this is the habit of most people, right?), The performance of the battery will not be affected? Oh, this may be a very food right? Hope reply. Thank you
A: a typical laptop battery charger design is less than 95% will be in charge, and because of the presence of natural wear and tear, so the loss for the battery, remove or not remove the basic are the same, so if removed as the habit may be, if you remove the battery wrapped in a fresh proposal membrane and placed in a dry cool place, and I remember a month or so and charge the battery at least once in order to avoid cell loss of activity. There are users that the use of alternating current, do not remove the battery charge and discharge will be repeated to reduce the battery life, in fact, the general life of the battery is fully charged according to the number of calculations, Li batteries are generally 300-400 times. Of course,do not have to worry about the battery power on a single charge, even if only one point will be counted once, rechargeable battery generally only when the power to 80-90% of the total charge will be increased, otherwise the battery does it mean that 1 month to scrapped.

First, the documentary and artistic:
The works of many sports photographers the full show, a documentary photo to a sporting event can be completely artistically creative way to shoot, but an artistic documentary sports photos is not necessarily without value. Newspapers in general have a photo documentary requirements, to reflect the game's defining moment. Need to introduce the reader is not the photo shooting skills, but the public in a matter of concern at the time, such as unexpected scores, Nade's defeat, the rise of rookie, and the celebration ceremonies. The art of photography magazines or other publications require photo composition and beautiful, expressive content, with high artistic value and enduring.
Second, the amateur photographer's Advantages:
Amateur photographers is that the biggest advantage of the absence of mental burden. He does not record the action superstar. He could easily Seek shooting scene, choose the subject. For the art of sports photography, the game's name is irrelevant, it is important gesture photo and photography athlete's performance capacity. A small-game pictures of beautiful,HP ProBook 4330s battery no doubt a big game than the poor picture much better.
Third, the photographer's training:
First, research. To take a sport which, we should have full access to this sport, to understand its characteristics. Only the most exciting way to foresee what the scene will appear when and how to seize the opportunity to capture vivid scenes.
Second, sophisticated techniques. Physical exercise is characterized by rapid change. This requires the photographer to be agile, skilled operation, in a very short period of time adjusted the aperture, distance, and shoot. This ability is only through a lot of practice to master.Dell Inspiron N5010 adapter
Fourth, the key to success:
For a successful work, it is important to arouse emotional responses. Whether a sports photo praised by others, mainly how the technology is not the superb shooting, but rather the information content of pictures. The greater the amount of information conveyed by photographs, the higher the quality of information (ie shooting more with the way the original), photos of the appeal will be. However, the information does not necessarily talking about here refers to a documentary to a sporting event itself, the situation is any other information. For example, the speed of movement performance, the audience's emotions, facial expressions of athletes, and the shares were elated, and so an air of dejected losers. Static and dynamic, beautiful, innovative, detail features, space and color can also have a high information content,battery for Dell XPS M1730 if used properly, for photographs to convey the content.
Photos of the value and appeal of the persistence depends on two factors: the "what" (theme) and "how" (composition). The combination of the two decisions picture quality. "What" mainly by personal interest and asked him who the request of the decision. "How," mainly by the personal style and preferences of decision.
Fifth, several special methods:
Since sports is changing fast and moves to its characteristics, the photographer should be to show these features in the photo. Depending on the circumstances he must be able to use some special shooting methods.
Action "freezing": This is the most commonly used method. Re-emerged in a clear and true to his face and body contour, people to see the result of too fast and could not see the details at the time. The following table lists the minimum in different situations shutter speed:
In the case of poor light, even if a large aperture opening can not obtain the required shutter speed. At this time an action should be the climax, when close to completion, that action tends to stagnate in the past to change direction to capture the moment.
Following the shooting: the direction of motion along the target, move the camera steady, rich in the target position in the viewfinder is always the same, and in the decision to move while pressing the door. This method can be used to take the road in the sprint athletes, riders and drivers. Its effect is to clear the image of athletes, and the background blurred. Advantage is to avoid damage to the busy background images at the same time, the background to bring out the fuzzy action fast. Shutter speed to follow the law, usually 1/15-1/60 seconds. In the case of not sure, you can use the same target shooting a few different shutter speeds for selection.
Blur effect: a lower shutter speed shooting fast action, hazy images will appear blurred outline. In this way, not only can produce movement, but also show that the action fast. Level should be moderate, however vague, too vague and would not identify the body, not misleading picture is fuzzy defective. Try different shutter speeds can be compared. Reduce the shutter speed, aperture go far too high, the town can be gray filter, polarizer, or the red filter (color film can not be used.) But the use of filters will cause the town changes color and tone.
Zoom: press the shutter head while promoting zoom lens, the lens focal length by a long short. This method can slow the action a "speed up" Thinkpad R32 Battery effect, very in the drama. The outline of the main body along the diagonal direction from the center of the screen extended to the surrounding, as if to explode toward the camera. This effect can only be obtained with a lower shutter speed (1 / 15 sec - 1 sec), so it is best to use a tripod.
