Multiple exposure (in-camera)
Meervoudige belichting (in-camera) · Technique
Combining two or more exposures within the camera into a single image.
Many modern cameras support in-camera multiple exposures. You choose how many shots are combined and how (additive, average, dark, light). Great for creative effects: a portrait combined with a texture, or doubled star trails. Also popular in analogue photography: resetting the film advance was the classic method.
