The Kodak 106 7214 Tri-X 400TX is a professional-grade, panchromatic black and white 35mm film with an ISO 400 sensitivity, ideal for versatile photographic applications. This 100-foot bulk roll allows for custom loading into reusable cassettes, offering cost efficiency and flexibility for frequent shooters. The film delivers a classic, high-contrast aesthetic with rich tonal gradations and fine grain, suitable for capturing detailed images in various lighting conditions. Its wide exposure latitude provides forgiveness in challenging light, while the panchromatic emulsion ensures natural rendering of colors as shades of gray. Designed for subjects requiring good depth of field and high shutter speeds, it excels in extending flash distance range and is well-suited for portrait, street, and documentary photography. The film develops reliably in standard black and white chemistry, maintaining consistency across batches. Packaged in a yellow-labeled bulk roll, it supports professional workflows with its long-length format, enabling extended shooting sessions without frequent film changes. This product is a successor model of earlier Tri-X formulations, continuing Kodak's legacy in monochrome imaging with enhanced performance characteristics for modern darkroom and digital scanning processes.
