Tri-X has undergone a number of minor engineering changes during its long history. An early change in ASA (ISO) speed from 200 to 400, around 1960, was due to a change in the ASA standard rather than the film.

Tri-X also exists as a reversal film for the 16 mm and Super-8 cine film formats. The speed for tungsten lighting (3200 K) is ISO 160 and for daylight ISO 200 when processed as reversal. It can also be processed as a negative at a small loss of speed while the grain will be slightly increased.
