framkallare

Framkallare is a Swedish term that translates to "developer" in English, and it most commonly refers to the chemical solution used in traditional film photography to develop latent images. When exposed photographic film is immersed in a developer solution, the silver halide crystals in the emulsion that have been struck by light undergo a chemical reaction. This reaction converts the exposed silver halide into visible metallic silver, which forms the basis of the photographic image. Different types of film and desired results may call for different developer formulations, affecting factors like contrast, grain size, and image sharpness. The process requires careful control of time, temperature, and agitation to achieve optimal development. Beyond photography, the term "framkallare" can sometimes be used more generally to describe something that brings something else into existence or makes it visible, though its primary association remains with photographic processing.
