Foma Fomabrom Variant 112 17.8×24 cm, 25 sheets is a silver‑gelatin black-and-white photographic sheet paper designed for traditional darkroom use. Supplied as a pack of 25 sheets in the 17.8×24 cm format, this paper is formulated for contact printing and enlarger work in analog processes. It is intended for photographers, educational labs and studios that require consistent tonal rendering and convenient handling for small print runs or test prints.

Advantages

The paper delivers stable image quality with predictable shadow and highlight reproduction across multiple sheets. Its sheet format simplifies processing, reducing paper waste when making small batches or test exposures. The surface and emulsion are engineered to provide reliable adhesion of silver image particles and uniform development results when used with standard black-and-white chemistry. The 17.8×24 cm size is convenient for contact prints from medium-format negatives and for trimming to custom sizes.

How to use

Handle sheets by the edges in subdued light or under safelight conditions appropriate for silver-gelatin paper. Expose using contact printing or an enlarger according to your negative density and desired contrast. Process the sheets in developer, stop bath and fixer using recommended concentrations and temperatures for resin-coated papers, then wash and dry following standard darkroom procedures. For best results, test exposure and development times on a single sheet before producing multiple copies.

Usage recommendations

Store unopened packs in a cool, dry place away from direct light and strong chemical fumes. Use gloves or clean hands to avoid fingerprints; flatten sheets before exposure to ensure even contact. When adjusting tonal scale, control contrast via exposure time, developer strength or contrast filters suited to silver‑gelatin papers.
