In Reply to: Where to develop old film posted by J. Runestad on October 08, 2000 at 10:16:02:
A latent image begins to deteriorate the instant you take the picture. It's very unlikely anything would be left after 30+ years; also the developing chemistry was different then, as you were told. If it were black and white film a lab could at least try - but I don't know anyone who still has the old C-22 chemistry available.
Editor's Note: Yes, an undeveloped image begins to deteriorate after the picture has been taken and before the film is developed but images are frequently obtained from film developed 30 years after the fact. Are they as good as they would have been had they been developed immediately? No. The most important consideration is how the film has been stored since it was exposed. Prolonged exposure to high heat and humidity would further damage the latent images. C-22 chemistry can still be produced because the formulas are public. (See the next message.)
