What else can I help you with?
Why should you store silver bromide in brown bottles?
Silver bromide reacts chemically when exposed to light, which is why they use it to make photographic papers.
How were UV waves discovered?
Photographic plates still darkened when exposed for making spectrograms in areas beyond violet where no visible light could be seen.
What does calcium iodide do in photography?
Calcium iodide is used in photography primarily as a photographic emulsion component, where it acts as a light-sensitive material. When exposed to light, it can facilitate the formation of latent images on photographic plates or films. Additionally, it may be involved in the development process, helping to create contrast and enhance image quality. Its properties contribute to the overall sensitivity and effectiveness of photographic materials.
What is silverbromide?
Silver bromide is a chemical compound commonly used in photographic film. It is sensitive to light, making it ideal for capturing images. When exposed to light, it undergoes a chemical reaction that forms the latent image on film.
What is photographic film?
Photographic film is a light-sensitive material used in analog cameras to capture images. It consists of a transparent substrate coated with layers of light-sensitive silver halide crystals. When exposed to light, these crystals form latent images that are later developed into visible images through chemical processing.
When photographic film is exposed to light what metal is formed?
silver halide
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"
How do x rays affect photographic plates?
X-rays will "Fog" photographic plates. That means the plates act as if 'exposed' to light. If the X-rays are intense enough, the plates will appear to be totally exposed.
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.
Why should you store silver bromide in brown bottles?
Silver bromide reacts chemically when exposed to light, which is why they use it to make photographic papers.
Describe the ways in which the unprocessed photographic paper can get damaged in transit?
When undeveloped photographic media is exposed to light or radiation (x-rays included), it can be exposed. It can also be damaged by exposure to water or other liquids. Physical damage can also be done by rough transportation, like rips, tears and folds.
What is light sensitive paper and how does it work?
Light sensitive paper is a type of photographic paper that changes color when exposed to light. It contains light-sensitive chemicals that react to light by darkening in areas exposed to light, creating a visible image. This process is used in traditional darkroom photography to create prints from film negatives.
How were photograms invented?
A photogram is a photographic image made without a camera by placing objects directly onto the surface of a light-sensitive material such as photographic paper and then exposing it to light. In a darkroom, or a darkened room, objects are arranged on top a piece of photographic material, usually photographic paper. When the operator is satisfied with the arrangement, the photographic material is exposed with light, usually by switching on an enlarger or other artificial light source. The material is then processed, washed and dried. The usual result is a negative shadow image that shows variations in tone that depends upon the transparency of the objects used. Areas of the paper that have received no light appear white; those exposed through transparent or semi-transparent objects appear grey.
How were UV waves discovered?
Photographic plates still darkened when exposed for making spectrograms in areas beyond violet where no visible light could be seen.
How is an x-ray film different from a photographic film?
Basically its the same stuff - but you can wrap it differently because it will never be exposed to visible light (in normal usage).
What element forms nitrate used in photographic toners?
Nitrate ion (NO3-) is composed of nitrogen and oxygen, making it essential for the formation of nitrates used in photographic toners. Nitrate compounds are often used in photography for their light-sensitive properties and ability to form images when exposed to light.
