Double exposure is a photographic technique, also known as multiple exposure, in which two separate images are superimposed onto a single frame. This effect can be achieved in-camera or digitally, creating artistic, surreal, or layered visual effects.
Photographers use double exposure to combine subjects, textures, or scenes in a single composition, adding creative depth and visual interest. In traditional film photography, careful planning and precise exposure control are required, while digital tools allow for easier experimentation and fine-tuning of the combined images.
