How are traditional photos developed?

Nowadays, color magnifiers are mostly used, but the working principle is the same as manual operation.

Firstly, the film enters the black box processor for development, development and fixing, then it is washed with water and dried at high temperature.

After the film is finished, it enters the paper machine, including the exposure of the film (that is, the process of restoring the shadow on the film to the photographic paper), the development, fixing and washing of the photographic paper, and then the drying process to the automatic cutting of the photo.

Developing, fixing and fixing solution are all chemicals, and the working temperature of color development is generally 37 degrees.
