What else can I help you with?
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"
Is there silver in unexposed xray film?
Yes, unexposed x-ray film contains a layer of silver halide crystals suspended in a gelatin emulsion. When exposed to radiation, these crystals undergo a chemical change, allowing for the development of images. The silver in the film is crucial for capturing the x-ray image, but it remains inactive until the film is developed.
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 happens to photographic film when it is exposed to electromagnetic radiation and then developed?
When photographic film is exposed to electromagnetic radiation, such as light, the silver halide crystals in the film emulsion undergo a chemical change, forming a latent image. This latent image is not visible until the film is developed, during which it undergoes a series of chemical processes, including development, stopping, and fixing. The developer reduces the exposed silver halide crystals to metallic silver, creating a visible image, while the fixer removes unexposed crystals, stabilizing the image. The result is a negative or positive image, depending on the type of film used.
What are the 3 layers of x-ray film?
X-ray film typically consists of three main layers: the base layer, the emulsion layer, and the protective coating. The base layer, usually made of plastic, provides structural support. The emulsion layer contains silver halide crystals that react to radiation, forming the image when developed. The protective coating safeguards the emulsion from damage and environmental factors.
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"
