What do you mean by multiple exposures?
There are also different options for multiple exposures. Ordinary SLR has two options, adding and averaging, that is, choosing the combination of photos, while high-end cameras also have "bright" and "dark" options.
1, supplement: The camera will not automatically adjust the exposure value, and the photos will be superimposed directly, so the composite photos may be lit.
2, average: the camera will automatically adjust the exposure, so that the combined photos keep normal brightness.
3. Brightness: The camera will keep the exposure of the brighter places in the previous photos and synthesize them. And "darkness" is just the opposite.
Extended data
Preset positions in some areas of the picture and multiple exposures in reserved areas can also form a very expressive effect. During shooting, the position of the camera can be fixed or moved. Here, we use a fixed camera position to take multiple photos of a person in multiple positions and then synthesize them together.
Although multiple exposure is rarely used in daily shooting, it is really effective in some special occasions, such as fireworks shooting and night shooting.
Digital camera has powerful post-processing advantages that traditional cameras can't match. It is easy to achieve multiple exposures when multiple photos are superimposed and fused in Photoshop, that is, two or more films with the same background are placed in the same picture in a multi-layer way, and then the "Brightening" mode is selected when the layers are fused, so that the effect of multiple exposures can be achieved.
