fotofilmer

Fotofilmer is a term that refers to the creation of photographic film, particularly in the context of its manufacturing process. This involves a complex series of chemical and physical steps to produce a light-sensitive material that can capture images. The core of photographic film is a base, typically made of cellulose acetate or polyester, coated with an emulsion. This emulsion is a suspension of silver halide crystals in gelatin. When light strikes these crystals during exposure, it triggers a chemical change that forms a latent image.

The manufacturing of fotofilmer is a highly specialized industry, requiring precise control over temperature, humidity, and chemical purity. Different types of film, such as black and white, color negative, and color reversal, are achieved through variations in the emulsion composition and the inclusion of different layers sensitive to specific wavelengths of light. The development process, which follows exposure, further transforms the latent image into a visible one through chemical reactions. While digital photography has largely superseded film for many applications, the art and science of fotofilmer continue to be appreciated by artists, enthusiasts, and in niche industrial uses.
