Double Exposure

Biography
Double exposure is a photographic and cinematographic technique. It refers to the superimposition of two exposures to create a single image, resulting in something similar to the effect of audio convolution that captures aspects from both sources. An image that is exposed to light twice contains the subsequent image layered over the original. It is a visual effect frequently used to create ghostly images, or to add materials that were not originally present.
