Kodak Tri-X Reversal Film 7266 offers fine grain and sharpness, and includes Eastman Keykode Numbers for easy cross-reference of shots in minutes, not hours. Reduced static support allows for a cleaner image throughout the film-making process. And because our films don’t require processing in a bleach containing heavy metals, they’re easier on the environment. This film provides the rich blacks and excellent contrast you’ve come to expect from Kodak Black & White Reversal Film. Kodak Tri-X Reversal Film 7266 is a medium-speed (ISO 200), panchromatic black-and-white film with an anti-halation undercoat that makes it suitable for general interior photography with artificial light.
