👉 Photostater is a device used in photography to enhance the color and brightness of an image. It consists of a light source, often a flash or a metered camera, that projects bright flashes onto a plate or screen where the image is placed. The light from the flash causes the image on the plate to be brighter than normal due to the increased exposure. This effect can make the image appear more vivid and colorful, enhancing the overall appearance of the photograph.
