Kodak’s Professional Tri-X 400 Black and White Negative Film is a classic high-speed panchromatic film designed for a wide array of shooting conditions. Characterized by its fine grain quality, notable edge sharpness, and high resolving power, Tri-X 400 also exhibits a wide exposure latitude with consistent tonality. It has a nominal sensitivity of ISO 400/27 when developed in standard black and white chemistry, and responds well to push processing. As an all-around, highly versatile film, Tri-X 400 is a standard choice for photographing in difficult lighting conditions as well as when working with subjects requiring good depth of field or for faster shutter speeds.This is for one 120 roll film
