KODAK T-MAX 400 Professional Film is a continuous-tone panchromatic black-and-white negative film especially useful for photographing dimly lighted subjects or fast action, for extending flash distance range, and for photographing subjects that require good depth of field and fast shutter speeds with maximum image quality for the film speed. It is also useful for scientific and biomedical work, especially when fluorescence photography is required. It has high speed (ISO 400/27° in most developers), very high sharpness, extremely fine grain, and high resolving power; it allows a high degree of enlargement.
