What happens if you under-develop your film?
If you under-develop the film because you've used an old developer and haven't compensated for this with longer development time, then there's nothing you can do about it. After fixing, you can't go back and give it another go in the developer. Your negative will be thin, and you won't be able to get decent contrast in the final print.
How long does film last before it goes bad?
While Kodak recommends processing within a day or two, most modern films are unlikely to lose detail or change colors so long as they are processed within six months or before the film’s expiration date. If you plan to leave the film longer, it will be best to store it in the freezer.
What happens if you leave hair dye in too long?

What happens if you leave a film in the developer too long?
If you leave the film in the developer too long, the film is overdeveloped. The result of over development is increased contrast, along with increased density in the mid tone and highlight areas of the picture. There is usually no real or significant chance to real film speed, which is measured by the lowest shadow densities.
What happens if you expose and under develop?
If you expose normally and over develop, the image becomes much thicker. When printed, it appears as though you over exposed (or over developed) the image.
What is the inverse of development?
Another inverse mechanics of development, is temperature. The warmer your developer, the more active it is. The cooler, the less active it is. Therefore, given a normal exposure, but cold developer, you effectively under-develop the film. And a normal exposure with a hot developer, you end up over developing the negative, making it thicker. The inverse of temperature is therefore time. If you have a hot developer, you must cut your development time. Too hot, and you will get an effect called reticulation (a condition where the silver in the negative clumps up).
Is film development a chemical reaction?
The speed at which this particular chemical reaction, indeed most, if not all chemical reactions, proceeds is temperature dependent. Cooler temperatures slow it down. Higher temperatures speed it up.
Why does film lose shadow detail over time?
The loss of detail is only most notable in the shadows because there are few developable grains there in the first place.
How should I process old film?
10+-year-old film should be processed using a slightly different method than more recent film. There is the usual guideline of adding one stop of exposure per year, but that isn’t always true when developing film that has been shot a long time ago.

Generalizations regarding fix times: Papers 45 to 70 seconds - Negative film emulsions 2 to 7 minutes. Time in solution is variable based on the thickness of the emulsion.
Why is the rapid fix formula used?
Because its activity is very energetic, films and papers left in the fixer, particularly when fresh, begin to attach the silver that comprises the image. This effect is more prevalent with fine-grained films and the tufts of silver are petite.
Is the fixer critical or reactive?
But the fixer is reactive, and for prints that are meant to last more than a very short time, it's something you want to get rid of. Otherwise you'll get that loverly yellow/brown patina of age in a hurry without the bother of toning.
Can you see if a print has oxidized?
The answer is yes, although you must have left the prints in the fixer for quite a while to see the staining immediately. It's usually something that creeps in over time.
