Texture is broadly defined as the surface character of an object. Texture screen is transparent film or glass printed with a fine background pattern. They're interposed between the image and the paper to break up large areas of tone or for special effects. T-Grain technology is the name for Kodaks film emulsion technology used in all Kodak APS films. Uniquely shaped grains that align better than conventional silver crystals absorb and transmitting light more effectively to produce sharper images.
Thermography is recording images by means of the heat radiated from the subject.
Thyristor flash gun is an automatic flash gun which cuts off the flash when the exposure is correct. This conserves power, makes recycling quicker, and battery life longer. Time and temperature are the controlling factors of a chemical photographic process. Time exposure is a general term for an exposure longer than can be set using the camera's fixed shutter speeds.
