Kodak T-MAX 400 is a continuous-tone, sharp panchromatic black-and-white negative film. Beyond usage as a fantastic black and white film for standard photographic purposes, it is also useful for scientific and biomedical work, especially when fluorescence photography is required. It is a high speed film, and its T-grain structure lends itself to very high sharpness, extremely fine grain, and subsequently is perfectly suited for enlargement. This black and white film also has a wider exposure latitude, making it more forgiving for any potential metering mishaps. Note that as with all medium format film, the number of exposures depend on the camera used.
