A paper safe is a light-tight container designed to store unexposed photographic paper safely. It typically features a secure, easy-to-open lid that prevents stray light from reaching the sensitive surface, protecting the paper from fogging or unwanted exposure.
Paper safes are essential in darkroom environments to maintain the integrity of photographic papers, ensuring that prints develop correctly and consistently. Using a paper safe helps photographers store and organise different paper types and sizes without risk of accidental light damage.
