Photography: How to shoot separation? They should have physical contact, such as ... liking ... the same person. Leave me alone.

For example, this photo, the same person, took two photos with different actions, and then combined the two photos with photoshop. Obviously, the scenery on the left and right sides, especially the tone of the characters, are different. Although some digital cameras now have the function of multiple exposures, in such a bright environment, it is impossible to achieve this fidelity by automatically synthesizing a photo through camera software after multiple exposures, and many overlapping and incomplete images will appear. Automatic camera composition requires a special environment to be realistic, such as the environment should not be dirty and the shooting space should be reserved.
