Photo paper Foma Fomabrom 142 N Chamois 20.3x25.4 cm 25 sheets

Foma Fomabrom 142 N Chamois is a silver gelatin fiber-based photo paper in 20.3 x 25.4 cm format supplied as a pack of 25 sheets. Designed for darkroom enlarging and traditional black-and-white processes, this paper features a chamois-toned surface that yields warm midtones and neutral blacks. The fiber base provides a tactile surface and archival stability suitable for fine art prints and professional silver-gelatin workflows.

Advantages

The paper combines a classic fiber base with a silver gelatin emulsion to produce rich tonal gradation and high image stability. Its chamois tone imparts a subtle warmth to highlights and midtones while preserving deep blacks and good contrast control. Sheets are sized for reliable handling in trays and on easels, and the fiber construction supports archival permanence when processed and washed correctly.
