Kodak's Professional T-Max 400 is a panchromatic black and white negative film with a unique T-GRAIN emulsion to provide very fine grain structure with a high degree of sharpness and edge detail. It has a nominal sensitivity of ISO 400/27° with wide exposure latitude to grade film up to EI 1600 and push development. Its versatility benefits working in difficult lighting conditions and with moving subjects, and its fine grain profile, wide tonal range, and high-resolution power scanning and enlargement applications. Additionally, the film is well suited to scientific and biomedical work, particularly where fluorescence in photography is required.
