Film Format and Speed

This is a 4x5 inch sheet film rated at ISO 320 and 26° DIN, supplied in a box of ten sheets. It is a panchromatic black and white negative film built for photographers who need high resolving power and classic grain structure in large format work. The emulsion suits street scenes, portraits and documentary projects where wide exposure latitude matters.

Exposure Latitude and Grain

The wide exposure latitude maintains consistent tonality across challenging lighting, so highlights and shadows hold detail without special development routines. Classic grain structure and exceptional edge sharpness translate into crisp detail on the negative, giving predictable results whether shooting in low light or stopping down for depth of field. The panchromatic response renders a broad tonal range for rich black and white prints.

Processing and Compatibility

Verify that your 4x5 film holders load this sheet size correctly and that your developer, stop bath and fixer are formulated for panchromatic black and white negative film. A darkroom or changing bag is required to load and unload sheets in total darkness. Ensure your enlarger or scanner can handle 4x5 negatives for the final workflow step.

Questions about this item

How should I store the 10 sheets of TRI-X 320 before use?

Keep the film sealed in its original packaging, refrigerated or frozen, until you are ready to load it; allow it to reach room temperature before opening to prevent condensation on the emulsion.

At ISO 320, what limits my ability to push the film further in low light?

The box speed of ISO 320 / 26° DIN is the rated sensitivity; pushing beyond that increases grain and contrast while reducing shadow detail, so the practical limit is how much extra grain you accept.

Does the film base generate heat or noise during long exposures?

No — TRI-X 320 is a passive photographic emulsion on a 4×5 sheet; it produces no heat, noise or power draw at any exposure duration.
