Made for capturing fast-moving or dimly lit subjects, the Kodak Professional TRI-X PAN 320 4×5 10 Sheets are a smart choice for scenarios where fast shutter speeds and a good field depth are required. Each sheet of film has a 7-mil ESTAR thick base, which makes it possible to retouch the film on the emulsion and base sides. For added practicality, you can push each film sheet to three additional stops at an ISO sensitivity of 1,600. Also, the sheets are capable of providing fine grain, classic-grain structure, wide-exposure latitude, high sharpness, and high resolving power.
