Fiber-based paper is a type of photographic paper that does not have a resin coating, relying instead on natural paper fibers to hold the emulsion. Because it lacks the protective resin layer, processing times are generally longer than for resin-coated papers, requiring careful washing and handling during development. Despite this, fiber-based paper is prized for its archival permanence, producing prints that can last for decades or even centuries when properly processed and stored.
Photographers who use fiber-based paper benefit from its superior tonal range, depth, and image quality, making it a preferred choice for fine art and gallery-quality prints. Mastery of this paper type requires patience and attention to detail during darkroom work, but the resulting durability and aesthetic richness make it a cornerstone of traditional black-and-white photography.
