Kodak's Professional T-Max 100 is a black and white negative film with a medium speed. It is known for its incredibly fine grain structure, delivering exceptional sharpness and detail in images. The T-GRAIN emulsion used in this film minimizes the appearance of grain during enlarging or scanning while maintaining its effective film speed. With an ISO rating of 100/21°, it offers a wide exposure latitude and a broad tonal range.

T-Max 100 is versatile and can be processed as a negative using standard black and white chemistry. However, it can also be used for reversal processing with the T-Max 100 Direct Positive Film Developing Outfit, allowing for copy and duplicate work. This film is well-suited for various applications and responds effectively to push development and the zone system for tailored development adjustments.
