Why do photographers use a red light in the dark room when developing film?

Photographers use this red light called a safelight because the paper onto which the photograph gets exposed is not sensitive to the frequencies emitted by the 'red' light bulb. This is for black and white Photography. Keep in mind, that although the bulb seems red, it has other filters, as opposed to a Christmas red light, or a red LED. These filters, usually block frequencies under (estimate) 590-650nm (nanometer). So anything above those frequencies the paper doesn't see, but we can, up until it becomes invisible light to us (350-700 nm is more or less what we see).

Because all the materials you use to do it with are light-sensitive and have to be handled in the dark.
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.
What is the effect of light on photosensitive film?
Too much light on photosensitive film can cause the picture to immediately corrode. This is why many photographers use a darkroom.
What is 'light-dark' when translated from English to Italian?
Chiaroscuro is an Italian equivalent of the English word "light-dark."

The pronunciation will be "KYA-ro-SKOO-ro" in Italian.
Why does a film developed in dark room?
The light will show on the film if its developed in the light
Is a dark room necessary for developing photographic film containing silver bromide?
You could try one of those light-tight bags that you put your hands and the developing canister into. If you can transfer film from the cassette to the canister in total darkness, doing it in the bag won't be much different. There are things you won't be able to do as part of the printing process, though.
Why do photographers store film in the refrigerator?
Film reacts to light and heat is closely related to light, think sunshine or touching a light bulb that has been on for a while, so keeping film in a refrigerator protects it from being affected by heat which will cause a red/orange cast over the image. (See links below)
In developing film negatives what does the developer do to the silver halides?
When developing film what does the developer do to develop the film?

Why do pictures come out negative in film rolls?
Film works by absorbing the light that hits it. The more light that hits an area on the film (meaning the brighter that part of the scene is), the darker the film will get. Slide film, which produces a positive image, works the same way. You get a positive image by developing the film, producing a negative image in the exposed silver grains, then developing the film again in a different developer that works on the silver grains not exposed in the camera.
If X-ray film is to dark what should you do?
If the film is too dark, the xray needs to be retaken with lower kV and mAS settings. Xrays that are only marginally too dark can be looked at under a bright light.
