What is emulsion paper made from?
Emulsion paper is typically made from a base paper coated with a layer of light-sensitive emulsion, which consists of gelatin and light-sensitive silver halide crystals. The emulsion layer allows the paper to capture and store photographic images when exposed to light.
What is the word equation of photographic film?
The word equation for photographic film is: Silver halide crystals + light → Silver metal + halide ions.
What is the active layer in film called?
an emulsion of small particles of a photosensitive silver salt (Usually silver halide) suspended in gelatin
When photographic film is exposed to light the salt on the film breaks down what metal is formed?
The "salt" you are referring to is actually called silver-halide and are more commonly known as "silver salts". When silver-halide crystals are exposed to light, they form a compound known as "metallic silver"
The film speed rating for black and white film is determined by A the size of the silver halide crystals in the emulation B the shutter speeds of the camera C the film base?
Are we doing your homework? It's A), and it's emulsion, not emulation
Is it true that the 2 main purposes of a fixing solution are to expose the silver halide crystals and turn the entire crystals into a block of metallic silver?
Yes, it is true that the two main purposes of a fixing solution in photography are to expose the silver halide crystals that have not been developed and to convert the remaining undeveloped silver halide into soluble compounds. This process ensures that only the developed silver crystals remain, turning them into a block of metallic silver, which is what creates the final image. The fixing solution effectively stabilizes the image, preventing further development and degradation.
The term used to describe silver and bromide atoms that combine to form the crystals in our film emulsion is?
substance
What are the components of radiographic film?
Radiographic film typically consists of an emulsion layer (containing silver halide crystals suspended in gelatin), a base (usually made of a flexible polyester material), and an overcoat layer to protect the emulsion. The film may also have an adhesive layer to adhere to the screens used in imaging.
When photographic film is exposed to light the salt on the film breaks down. what metal is formed?
The "salt" you are referring to is actually called silver-halide and are more commonly known as "silver salts". When silver-halide crystals are exposed to light, they form a compound known as "metallic silver"
What compounds of elements are used to make photographic film and paper?
Usually, either polyester or acetate substrates, coated with emulsion on the image side. In black and white film, the emulsion is a gelatinous substance containing silver halide grains that are sensitive to light. Color film emulsion contains silver halide in 3 layers with separation layers in between. The separation layers are designed to "channel" light to the proper layer, based on the color of the light. The sum of all the layers is thinner than a human hair! During development of color film, the silver is converted, then replaced with dye.
Why is silver nitrate added to halide salts?
Silver nitrate is added to halide salts to test for the presence of halide ions. When silver nitrate is added, a precipitation reaction occurs where silver halide compounds are formed. The color of the precipitate that forms can help identify the type of halide ion present in the salt.
What is X-ray film made of?
X-ray film is chemically sensitive film. It is created to react with the sourced light producing an image. It was made possible through the advances of Marie Curie and her studies of extracting radium from pitchblende.
