There are two applications of lenticular systems. They are used in some exposure meters to gather light and to determine the angle of acceptance of light by the meter. A lenticular screen consisting of a number of lenses et into rows can be used at the camera stage to produce stereoscopic images by synthesizing binocular vision. Lightbox is a box of fluorescent tubes balanced for white light and covered with translucent glass or plastic. Used for viewing, registering or correcting film negatives and positives.
Light meter is an alternate term for exposure meter .
Light sources is a general term applied to any source of light used in photography. Light tent is a tent like structure made of translucent material hung around a frame. The fabric diffuses the light coming from outside the tent so that highly reflective subjects placed inside the tent can be photographed without reflections. Light-tight is a term denoting a material or piece of equipment that is impervious to light. Light trail is an image track recorded on photographic material when a point of light is shifted during exposure.
