Kentmere 400 100' Bulk Roll

Kentmere 400 is a 35mm black and white negative film supplied as a 100-foot bulk roll for loading into reusable cassettes. It suits photographers who shoot high volumes and want control over frame counts per roll. The film is rated at EI 400/27 and offers usable exposure latitude from EI 200/24 to EI 1600/33. It works with all major processing systems and popular developers.

ISO 400 Speed and Fine Grain

The single specification that decides suitability is the ISO 400/27 speed combined with fine-grain emulsion technology. This speed allows higher shutter speeds or greater depth of field in lower light while maintaining sharpness comparable to medium-speed films. If your work demands a slower or faster fixed speed, this roll will not match that requirement.

High-Volume Shooters and Darkroom Users

This bulk roll suits photographers who load their own cassettes and process black and white film at home or in a lab equipped for standard developers. It is not for photographers who need pre-loaded DX-coded cartridges, colour negative or slide film, or instant-load convenience. Buyers without bulk-loading equipment or access to black and white chemistry should look at something else.

Questions about this item

What results can I expect from ISO 400 speed in a real camera?

ISO 400 lets you use faster shutter speeds or smaller apertures in typical indoor or overcast light while keeping fine grain and sharp detail.

What does the EI 400/27 rating tell me about metering and processing limits?

EI 400/27 is the box speed; the film tolerates exposure from EI 200/24 to EI 1600/33 and works in all standard black-and-white developers.

What do I need to load and store this 100-foot bulk roll?

You need empty 35 mm cassettes, a bulk loader or dark bag, and light-tight storage for the remaining film after cutting.
