Kodak T-Max 400 professional film offers high speed, very high sharpness, extremely fine grain, and high resolving power. It's especially useful for shooting fast action, for dimly lit scenes where you can't use flash, for subjects that require good depth of field combined with fast shutter speeds, and for hand-holding telephoto lenses for fast action or in dim light. This film is also useful for scientific and biomedical work, especially when fluorescent photography is required.
