Apple 1 1 How to set the edge black?

When taking pictures, you should choose a dark background, which is stronger than the light and shade of the object being photographed, so that the background itself is dark, and it can meet the requirements as long as it is properly adjusted later.

Artificial black background. If it is difficult to find the angle of the dark background in the shooting environment, it is ok to make one yourself, such as black paper and black cloth. Focusing and metering. Select the shooting conditions with white subject and dark background, and focus on the bright part of the subject on the mobile phone. The camera will also focus and measure the light in this area. Because this part is bright, the mobile phone camera will think that the environment is bright. In order to expose the bright part normally, the brightness of the whole picture will be reduced, thus darkening the background.

Fill the theme with light. If the ambient light is not bright, you can use the flashlight function of the mobile phone or another mobile phone to illuminate the subject, so as to artificially increase the brightness of the subject. When shooting, the mobile phone will automatically reduce the brightness of the whole picture, thus reducing the brightness of the low background. Lower exposure compensation. When a mobile phone is in focus, there is generally a sliding bar next to the focus frame that can adjust the brightness vertically. This is exposure compensation, which can brighten or darken the picture, ensure that the subject is not greatly affected, reduce exposure and darken the background.

Late adjustment. Even if the background is darkened in the early stage, it may not reach the black state, so the dark part can be darkened in the later stage, which can also meet the demand.
