The developing tank is a light-proof container that holds the film during the development process. It allows the developer solution to come into contact with the film and convert the exposed silver halide crystals into metallic silver.

Bleach is a chemical solution used in the processing of color film to remove the unexposed silver halide crystals from the film. It is not a type of film developer.

The fixer, also known as hypo, is a chemical solution used in film processing to remove the unexposed silver halide crystals from the film. This makes the developed image permanent and prevents it from fading.

The recommended temperature for developing black-and-white film is 20°C (68°F). This temperature ensures optimal development of the film and minimizes the risk of defects.

Agitation during film development is important to ensure even development of the film. It helps to distribute the developer solution evenly over the film surface and prevents the formation of streaks or uneven development.

APS (Advanced Photo System) is not a type of film format. It is a film cartridge system that was introduced in the 1990s but is no longer widely used.

The stop bath is a chemical solution used in film processing to stop the development process. It neutralizes the developer and prevents it from continuing to react with the film.

View camera is not a type of film camera. It is a large format camera that is used for specialized photography such as architectural and landscape photography.

The film leader is a short strip of unexposed film that is attached to the beginning of the film roll. It provides a space for attaching the film to the developing reel and helps to protect the film from light during loading and unloading.

The recommended time for fixing black-and-white film is 10 minutes. This ensures that all of the unexposed silver halide crystals are removed from the film and that the developed image is stable.

ISO 800 is not a standard film speed. The standard film speeds are ISO 100, ISO 200, ISO 400, and ISO 1600.

The wetting agent is a chemical solution used in film processing to help the film dry evenly. It reduces the surface tension of the water on the film and allows it to spread out more evenly, preventing the formation of water spots.

Ultra-fine grain is not a type of film grain. The standard film grain types are fine grain, medium grain, and coarse grain.

The film squeegee is a tool used in film processing to remove excess water from the film. This helps to prevent the formation of water spots and streaks on the film.

Polycarbonate is not a type of film base. The standard film bases are cellulose acetate, polyester, and polyethylene terephthalate (PET).
