What is surround exposure?

Surround exposure means that every time the shutter button is fully pressed, the camera will take three photos, one of which adopts the current exposure value, and the other two will change the compensation values of +05 and -0.5 respectively.

The method of bracketing exposure is to expose a photo according to the photometric value, and then increase and decrease the exposure on this basis. If you are still not sure, you can change your exposure and take more photos. The exposure can be adjusted according to the level difference of 1/3EV, 0.5EV, 1EV, etc. The exposure of each photo is different. You can choose a satisfactory one from a series of photos.

Extended data:

Automatic bracketing exposure is a method of "bracketing" multiple photos of the same object with different exposures to obtain the correct exposure photos. "Automatic" means that the camera will automatically take 2, 3 or 5 photos with an exposure between 0.3 and 2.0EV (the exposure of each photo is different).

When you are not sure whether the exposure is correct or not, you can use the automatic bracketing exposure function to ensure the accuracy of exposure and improve the quality of photos. The automatic exposure function on digital cameras even allows users to combine underexposed and overexposed photos into one accurately exposed photo-even if you don't have any accurately exposed photos when shooting.
