Frequently asked questions about digital photography
For a first shot with a digital camera novice, often encounter fuzzy photo, the focus is not correct, the dynamic is not clear and so on. Indeed, while digital cameras and traditional film cameras was much the same basic, but the camera itself, the structural differences, even if you have some experience of traditional film, when holding a digital camera, start shooting, there are some things that we place. Here I will introduce some of the most common problems of digital photography, and provide appropriate solutions.
Situation One: Indoor Shooting blurred
Sunny weather, outdoor photography, dell inspiron 6400 charger photo effects generally will not be a big problem. But to get the indoor use of natural light, and photos to often become blurred, fear of open atmosphere of flash photography.
Reason: due to indoor outdoor lighting generally more dark, if not destroyed by the atmosphere built-in flash, the camera's automatic exposure system will open the lens aperture to the maximum shutter value adjustments will also be larger. In the case of slow shutter shot, as long as there is a slight manual, or take a little characters move will make the photos blurred.
Solution:
(A) of the camera mounted on tripod shooting, you can avoid shaking situation.
(B) increase the value of the camera's ISO light-sensitive, usually at least have a digital camera to ISO400 ISO100 sensitive value for the user adjustment. As long as the ISO value adjusted to ISO400 or more sensitive, the shutter when shooting outdoors and need not set the value too slowly, even if the hand-held camera, the general situation can be improved fuzzy photos. However, to note that the higher is the value of ISO photographic, photos will appear on the noise the more effect.
Situation Two: Focus is not correct after the clear front dim
According to the daily life shot, often encountered when the people being photographed is not in center of frame, the background will appear clear, but Zhujiao but dim and bleak situation.
Reason: dim before the advent of the situation after the clear, mainly due to the camera when shooting did not take on the character was going to focus on the result. Because the focus of most SAMSUNG bp70a battery digital cameras will default to the middle of the screen, so when people are not making the middle of the screen, and users have no way to properly deal with the case, the camera's autofocus and metering system will incorrectly when the background for the subject to shoot, resulting in people being shot hazy and bleak.
Solution:
(A) of the first center of the screen shot of focus aligned to the characters face, half press the shutter button halfway to focus and metering program, according to the shutter button down, move the camera to want to shoot landscape composition.
(B) If the digital camera itself has more than one focus point, so long as the focus will be adjusted to direct the characters to take on. Or use the camera's own auto-focus, the camera automatically selects the nearest point to as a focus, in order to achieve the same effect.
Situation Three: The overall effect of bleak
Although outdoor shooting, but the overall effect of photo is still dim, of course, the more people are making bleak it! Flash photography will be too afraid to open the bright spot at the expense of the environment of natural light.
Reason: the sky dark, the scene less than ambient light, or light source is shot toward the person is not a party to the case dim photo will appear.
Solution:
Encountered such a situation can not have flashing lights, the best way is to use most digital cameras have built-in exposure compensation function. Just push the exposure compensation one to two, the general situation will improve dim, which required it to use flash photography!
Situation Four: The dynamic effect is not ideal
When shooting fast-moving person or object, there are often unclear or even not taken the case.
Cause: The value is generally set by the shutter did not learn fast enough and press the shutter button and the time gap between the real shooting.
Solution:
(A) the use of some Dell Inspiron 1521 battery charger digital cameras have shutter priority (Tv) shooting mode, self-adjust to a more high-speed shutter values, such as 1 / 500 seconds, or even 1 / 2000 second, etc., the sooner the better shutter to capture fast-moving subject. But how fast the shutter of the set, as the spot is still light enough in low light situations, the shutter set photos will darken too quickly.
(B) the use of most high-end models have built-in high-speed continuous shooting function, you can photograph in one second the number of photos, with a high shutter value is set, the number of photos may be elected in a certain most of their preference for one.
Five conditions: night shooting was not King
Portraits at night, must use built-in flash, but behind the beautiful night view in the photo is gone, a pity!
Reason: Using built-in flash, shutter value is automatically adjusted too high, due to the exposure time is not enough, so low light night, you can shoot well in the photo.
Solution:
(A) of the camera installed on the tripod, and then use Tv Shutter Priority function, adjust the shutter to a slower speed, such as 1 to 2 seconds, long exposure shot that night were repeated. However, in the middle of the exposure will not be making people move, or will become blurred.
(B) the use of digital cameras Slowsync flash mode, flash photography, to continue the exposure time can make the background of faint light sensitive, so that people can be guaranteed to be shot and the night could be clearly reproduced in the photo. However, the background is still blurred found, it could still be shot on camera installed on the tripod.
