22 ESTAR-base 35 mm (or larger) camera film
23 ESTAR-base 35 mm (or larger) lab/print film

A "T" suffix designates a tungsten (3200K) balanced negative and a "D" suffix designates a daylight (5600K) negative. The number preceding this is the film's exposure index as determined by Kodak (it is NOT ISO speed).
