fotolak

Fotolak is a term that primarily refers to a type of photographic emulsion or coating. Historically, it was a common name for lacquers or varnishes used in early photography to protect and enhance photographic prints. These formulations often contained natural resins like gum dammar or shellac, dissolved in solvents. The purpose of applying fotolak was to give prints a glossy finish, prevent scratching, and provide a degree of moisture resistance.

In some contexts, "fotolak" might also be used to refer to specific brands or types of photographic chemicals or materials, particularly those manufactured or popular in certain regions or historical periods. The exact composition and application methods varied over time as photographic technology evolved. While the term is less prevalent in modern digital photography, it remains a relevant descriptor for historical photographic processes and materials. Understanding fotolak provides insight into the techniques and materials used by early photographers to preserve and present their work.
