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 else can I help you with?
Do dried cranberries have seeds?
Dried cranberries typically do not have seeds. During the processing of cranberries, the seeds are usually removed before the fruit is dried. As a result, the dried cranberries you find in stores are seedless and ready to eat.
What is the correct procedure for photo processing?
The correct procedure for photo processing is to soak the film in developing fluid inside of a dark room. After taking the film from soaking it is dried and placed into a machine that projects the iamge onto the paper. After the image is burnt onto the paper, that paper is moved into a bath of developing fluid into the picture appears. Then they are hung to dry.
When is acetyl produced?
During pyruvate processing
How to dye cow hide?
During processing, leather can be dyed with a variety of pigmented chemicals. Once the leather has been dried and sealed, however, it generally cannot be stained evenly.
When a photographic film is exposed to light then salt on the film breaks down what meatel is formed?
The short answer is silver. In black and white film and print technology, the silver halides created by exposing the film to light in the camera or on paper under an enlarger, are reduced to silver by the developer and then the remaining halides are washed from the film during the fixing process. In some color photography, ALL of the silver is washed from the film and replaced by dyes introduced during the processing.
What is meant by the term - 'reticulation of radiographic film'?
Reticulation of radiographic film refers to a pattern of fine lines or a mottled appearance that can occur on the film due to improper processing. This phenomenon is often caused by extreme temperature changes during the developing process, particularly when the film is rapidly cooled or heated. It can compromise the quality of the radiographic image, making it difficult to interpret. Proper temperature control and processing techniques are essential to avoid reticulation.
What causes fogging in radiography film?
Fogging in radiography film can result from various factors such as light exposure, heat, humidity, or radiation exposure before or during the imaging process. It can also occur due to improper storage of the film or contamination during processing. Fogging can affect the quality of the image by reducing contrast and increasing background noise.
What are industrys in California?

What are the key steps involved in processing black and white film?
The key steps involved in processing black and white film include developing the film in a darkroom using developer, stop bath, fixer, and water, then rinsing and drying the film before it can be printed or scanned for final use.
What are the release dates for Processing - 2007?
Processing - 2007 was released on: USA: 26 January 2007 (Slamdance Film Festival)
How Photo Processing Works?
Photo Processing involves chemically treating photo film and paper in order to yield a visible image. The film and paper is put through a series of chemical treatments and needs to be maintained at a specific temperature during its treatment time. Photo Processing is usually done in a photo lab and can be completed in a short time span which is why many photo labs offer one hour processing. It can also be completed instantly at digital processing kiosks that are offered at retailers. Many websites also allow digital photos to be uploaded and they will process and mail them.
Whatcolor light do you used to develope negatives in a dark room?
If you're developing roll film in light-tight tanks, any sort of light will do during the processing stages. If you're developing sheet film in open trays, no (zero) light can be used. Nor can you use any type of light during the loading of film on to reels that are used in the tanks.
