Film processing technology

To repeat operations according to technology of processing of a film.

The detailed information on technology of processing of a film, recipes of processing solutions, technology of preparation of these solutions you can receive from firms of the manufacturers of a film : Svema, Kodak, Fuji, Ilford, Agfa and others..

As an example, on this server, introduced the technology of processing of a B&W reversal OCH-L-200 200 ASA SVEMA film in details.

You can process on this technology and these solutions and of a reversal film and other firms, but with some updating of time of processing in solutions.

In any case the exact times of processing in solutions is selected by an experimental way.

Changing time of processing in solutions, saturation (activity) and temperature of processing solutions, you can achieve the special expressive means of your film. You can receive the image with very soft or especially contrast scale. Thus you can transfer the special atmosphere, mood of your film or separate scenes.

Changing time of processing in solutions, saturation (activity) and temperature of processing solutions, you can to increase or to reduce film's speed.

Using subtleties of process of processing of a film you open before yourselves unimaginable open space for experiments and expression of the plans..
