Shulou(Shulou.com)11/24 Report--

A very clear picture on the camera is sent to the computer and then it is found that there is a virtual shadow, and the details are very blurred after magnification, which may be due to the insufficient shutter speed.

Generally speaking, when shooting, the "safety shutter" will not appear in the state of blurred virtual shadow. The safety shutter means that the shutter speed is the reciprocal of the focal length of the lens or faster. If you shoot with 85mm focal length, then the shutter speed will be relatively stable when the shutter speed is 1max 85 seconds or faster.

On this basis, the half-frame is multiplied by a conversion factor of about 1.6, that is, when shooting with a half-frame 85mm, the safety shutter is 1-inch 85-1.6, that is, about 1136 seconds.

In the actual shooting, the "safety shutter" can be used as a reference, but specific to different shooting themes, we need to make it clear that the "safety shutter" can only be used as a basic guarantee, such as in the shooting of the sports scene, in order to ensure the clarity of the motion subject, we need to use a higher shutter speed, that is to say, the safety shutter can only ensure that the picture is not blurred due to jitter, not the clarity of the motion subject.

In order to keep the details clear, we can use these tips in our daily shooting:

1. If the brightness is enough, we can appropriately use a faster shutter speed when shooting sports or street sweeping, if the environment is bright enough, we can try to use a higher shutter speed, because there are many factors affecting the actual shooting. faster speed may help us to reduce mistakes and lock in wonderful moments.

If it is in the clear sun, then basically do not need to worry about the brightness, a few thousandths of the shutter speed can achieve normal exposure.

two。 It may be troublesome to check while shooting in time, but it is definitely a good habit when there is plenty of time, especially for the more complex shooting environment, we can ensure the quality of the photos by looking at the information of the photos. and adjust the blur and other conditions.

When viewing photos, we can focus on these pieces of information:

One is to enlarge the photo to see if there is any blur caused by shaking and insufficient shutter.

The second is to check whether the photos are in focus correctly.

The third is to see whether the exposure of the photo is accurate, only by the camera screen display is not enough to accurately judge, we can look at it with the help of histogram.

3. Do not rely solely on the formula and the experience of others, such as "safety shutter" is a reference, can only ensure the basic clarity, the specific scene should be analyzed in detail.

The experience of others is only suitable for reference, everyone's equipment, shooting habits, shooting scenes are different, and the shooting parameters are not perfect, so it can only be used as a reference. Like a busy street, some people like to capture instant pictures through the ultra-high speed shutter, while others like to record the light track through long exposure, each has its own understanding, each has its own sense of beauty, the important thing is our thinking.

4. Don't put too much faith in your "iron hand". Using a tripod can bring greater stability to our shooting. Instead of believing that your "iron hand" can break through the safety shutter rule, it is better to use more accurate props.

When you go out to shoot, if you need to shoot in a low light environment, it is best to prepare a tripod, do not find it troublesome.
