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.

Why red light is used in developing photographs?
Red light is used in developing photographs because it has the least effect on light-sensitive photographic materials, such as film or photo paper. This allows photographers to work in a darkroom without exposing their materials to white light, which would ruin the photos being developed.
What is the name of the light-sensitive pigment in rods?
The name of the light-sensitive pigment in rods is rhodopsin.
Which type of photoreceptor, rods or cones, is more sensitive to light?
Cones are less sensitive to light than rods.
Which type of photoreceptor cells, cones or rods, are more sensitive to light?
Rods are more sensitive to light than cones.
Why are rods more light sensitive compared to cones?
Rods are more light sensitive compared to cones because they contain a pigment called rhodopsin that is more sensitive to low levels of light. Cones, on the other hand, contain different pigments that are less sensitive to light but are able to detect different colors.
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 a photographic print made by placing objects on light sensitive paper and exposing it to light?
A photogram

How do you make normal paper sensitive to light?
Coat it with a light sensitive emulsion. Don't plan on making your own photographic paper that you will subject to the normal development process. It won't survive the chemistry.
Why do you rinse the sun-print paper after exposing it to sunlight?
It has light sensitive chemicals.
What do rayographs British algae cyanotype impressions and leaves on light sensitive paper have in common?

What is the purpose of Canon matte photo paper?
Canon matte photo paper is a paper used for photos. The photo paper is paper coated with a light-sensitive chemical formula. The purpose of this paper is to make higher quality pictures.
What and how do light sensitive polymers work?
They are used in hospitals as stitches because they will desolve in light and there is no need for them to be taken out.
Why does red light not affect film development?
Photographic film is by it's very definition sensitive to light. Different types of film is sensitive to different colour spectrum The first types of film had a very limited sensitivity to colours and only reacted to blue light. As technology progressed film was made sensitive to a wider spectrum of light.Orthochromatic film was (is) sensitive to colours from blue to green, thus not sensitive to red light hence not affected by a "red light" during development.This film type was, however, superseded by "Panchromatic" film that is sensitive to all light spectrum, including red light. This means that most (modern) film cannot be developed using a red darkroom light without permanently destroying the film.Copying images (to paper or plastic sheets) is a different matter as the light sensitive emulsion on copy-paper is notsensitive to red light which is why a red light can safely be used during copying and development of the copies.
Are worms sensitive to light?
Yes, they are sensitive to light.
Why red light is used in developing photographs?
Red light is used in developing photographs because it has the least effect on light-sensitive photographic materials, such as film or photo paper. This allows photographers to work in a darkroom without exposing their materials to white light, which would ruin the photos being developed.
What is safe light in a dark room?
Safelights are used when printing. They're made to produce only light of a color the paper being used isn't sensitive to.
