Fogging (Fog)
A produces an overall veil of density on a negative or print, which does not form part of the image. It can be achieved by chemicals or exposing the sensitive material to light.

Fogging problems affect only high-speed infrared film.
Okay. Before I get any further, however, I should mention that I'm primarily dealing with Kodak HIE infrared film in this document.

Fogging
Density produced on a negative, print or trannie by chemical processing or accidental exposure to light, caused by
1. exposure to non image-forming light (possibly: opening the camera back in daylight),
2.
-Anti-fogging agent - constituent of a developer that inhibits or reduces fogging during development.

is a fogging color development, and solarization is not feasible at this point because all of the silver halide grains remaining in the emulsion are reduced in this step, even with normal processing.
If the fogging happens on the unexposed-but-processed film, try a different lab.
To avoid fogging your lenses, and to make a more overall enjoyable experience when photographing stars, make yourself comfortable. A cheap pup tent of sufficient height can house your expensive tripod, telescope, camera, your equipment, and you.
FOG or "Fogging" - Unwanted density in an image caused by accidental exposure to non-image forming light or X-rays, poor storage conditions or improper chemical processing.
SLR cameras have focal-plane shutters directly in front of the film so the lens can be removed and replaced at any time without fogging the film. Most makes of lenses and cameras are designed with their own exclusive method of lens attachment.
Gross fogging can turn film or prints completely black. Slight fogging will cause reduced contrast and is generally pretty bad news.It is also possible to fog chemically. film leader Shaped portion at the start of 35mm film used to aid loading.
But they add a new possibility of fogging film. For us photographers, that's bad. What to do? Industry experts advise that you carry all film in your carry-on luggage and pack no film in luggage you check.
If you breathe on your camera you risk fogging it. The heat from your eye could also cause problems on the viewfinder.
Prevent lens optics from fogging up by avoiding dramatic changes in temperature. If it’s safe to do so, store your gear in your car boot the night before or at least get it outdoors before you get yourself ready.
Nikon didn't address the fogging of the inside rear glass of my LCD; my D3 came back just as I sent it to them. You only can see this fogging with the LCD off and bright light shining on the rear LCD.

Fogging - degradation of a photograph caused by stray light leaking onto the film or sensor, or by faults in developing, usually resulting in white areas on the final (positive) image.
Back in the days of IR film, you had to use special film and load and unload your camera in total darkness to reduce the damage of fogging.

Where you accidentally expose an unprocessed film to light and create an unwanted veil of density. Sometimes cameras have a light leak around the sealed film chamber and the fogging appears as orange streaks spreading across the film.

Many medium and large format cameras allow for the "backs" to be switched midroll to allow for varying films to be used. In order to change backs a dark slide is placed between the film and the outside world preventing fogging of the film.
that can be placed in and removed from the camera in daylight. Some nature of film, like the infra red film, MUST not even try to load or unload film in any possible light existence, absolutely must be in total pitch dark condition to avoid fogging ...
RestrainerA restrainer is added to prevent the developer and the accelerator from working so quickly as to cause chemical fogging, or reduction of un- or underexposed silver halides. Simultaneously the restrainer helps control excessive contrast.
