What does multiple exposure photography show?

Multiple exposure is a technical method in photography, which uses two or more independent exposures and then overlaps them to form a photo. Because the parameters of each exposure are different, the final photo will have a unique visual effect.

It can be said that the multiple exposure function is the product of the film camera era. In traditional film SLR cameras, multiple exposure is a very important function and a unique photography technology. The principle of multiple exposure technology is to shoot multiple images on one film, so that a subject appears in the picture many times, which can shoot magical effects out of nothing.

This is its unique charm, attracting many people to use this technique.
