Friends in photography, there are many nouns around the camera. What do you mean, around?

For example, bracketing exposure is to add overexposed and underexposed photos at different positions on the basis of normal exposure. Usually take three or five pictures at a time. Different camera settings are different. In addition, you can set the changing position of the bracketing exposure, such as 1/3, 2/3, 1, and some will have higher-grade positions to choose from.

Some cameras also have film (such as Fuji's) and white balance around them. For the same reason. The purpose of these enclosed shots is to increase the selection effect of photos. On the other hand, for example, in the case of few shooting opportunities, such as large light ratio scenes, it is impossible to determine the exposure or post-HDR, and the enclosed exposure can ensure the best effect.
