<P> Eastman Kodak manufactures film in 54 - inch (1,372 mm) wide rolls . These rolls are then slit into various sizes (70 mm, 65 mm, 35 mm, 16 mm) as needed . </P> <P> Motion picture film, primarily because of the rem - jet backing, requires different processing than standard C - 41 process color film . The process necessary is ECN - 2, which has an initial step using an alkaline bath to remove the backing layer . There are also minor differences in the remainder of the process . If motion picture negative is run through a standard C - 41 color film developer bath, the rem - jet backing partially dissolves and destroys the integrity of the developer and, potentially, ruins the film . </P> <P> In the late 1980s, Kodak introduced the T - Grain emulsion, a technological advancement in the shape and make - up of silver halide grains in their films . T - Grain is a tabular silver halide grain that allows for greater overall surface area, resulting in greater light sensitivity with a relatively small grain and a more uniform shape that results in a less overall graininess to the film . This made for sharper and more sensitive films . The T - Grain technology was first employed in Kodak's EXR line of motion picture color negative stocks . This was further refined in 1996 with the Vision line of emulsions, followed by Vision2 in the early 2000s and Vision3 in 2007 . </P> <P> Fuji films also integrate tabular grains in their SUFG (Super Unified Fine Grain) films . In their case, the SUFG grain is not only tabular, it is hexagonal and consistent in shape throughout the emulsion layers . Like the T - grain, it has a larger surface area in a smaller grain (about one - third the size of traditional grain) for the same light sensitivity . In 2005, Fuji unveiled their Eterna 500T stock, the first in a new line of advanced emulsions, with Super Nano - structure Σ Grain Technology . </P>
