Velvia

Velvia is a brand of daylight-balanced color reversal film produced by the Japanese company Fujifilm. The original version of the film, was introduced in 1990 as "Velvia for Professionals", and given the classification code "RVP" meaning "Reversal/Velvia/Professional series". It is known for its extremely high level of color saturation and image quality. It has brighter and generally more accurate color reproduction, finer grain, twice the speed, and a more convenient process (E-6). Kodachrome 25 fell out of popularity a few years after Velvia was introduced (in part because of Kodak's lack of interest in promoting their film); Kodachrome 64 and 200 followed more slowly. Kodachrome 25 had previously been considered the film to which all other films had been compared, and cannot fairly be compared to Velvia, as Kodachrome is an entirely different process, in which the image is produced with "color clouds" more so than grain.

Velvia has the highest resolving power of any slide film. A 35 mm Velvia slide can resolve up to 160 lines per mm.
