if the film was not exposed to light it must be soaked in film fixer for 10 minutes and washed in running water for the same time.
if it was exposed is possible to try a strong acid but should be extremely careful and use
protective equipment on you such as goggles acid resistant apron and gloves and

Is gelatin called as emulsion?
yes
What is the active layer in film called?
an emulsion of small particles of a photosensitive silver salt (Usually silver halide) suspended in gelatin
Why is a film dried during processing?
Modern film are made using a flexible clear plastic base over coated with gelatin. The gelatin is the glue that holds the light sensitive chemicals to the film base. Gelatin is chosen because it is flexible, transparent, and porous. When the film is immersed in water, the gelatin swells. In this swollen state the chemicals of the developing process can penetrate and circulate within the gelatin. Since the chemicals used to develop film are dissolved in water, they are able to easily travel within the gelatin structure and do their job. After the film is developed the wet film is dried. As the gelatin dries it shrinks back to its original size. In earlier times, egg whites were used in place of gelatin. Film makers would like to replace gelatin for this task with something other than an animal product. Gelatin is made from the bone and hides of animals. Because gelatin works and because it actually boosts the sensitivity of the film (higher ISO), no substitute for gelatin has ever been found. The mixture of gelatin with the light sensitive chemicals imbedded within is called an emulsion.
What does a emulsion do on a camera?
The emulsion is the coating on a film in which the image is formed.
The active layer of film is the A film base B emulsion C anti-halation coating?

What are the sensitized materials?
Sensitized Material-l Refers to the film and photographic paper that basically composed of emulsion containing silver halides suspended in gelatin and coated on a trasparent or reflective support
Is an emulsion formed when a solid ingredient dissolves into a liquid?
True or false
What Swells and softens the film emulsion?

Photographic film is AgBr in a gelatin layer. What is the purpose of the gelatin layer in films?
It bonds the silver to the polyester film.
Which of these materials is an emulsion a. Gelatin b. Milk c. Paint d. Saltwater?
B and C. A is a colloid and D is a solution.
What part of the eye is like the emulsion of a camera?
The emulsion on the film of a camera is where the image is focused and captured. In the eye that function is performed by the retina.
