How long can I let freshly dated, exposed color negative film stay undeveloped (at room temperature) before I see any deterioration or change in the image (color shifts, darkening/lightening, etc). Thanks,
Vijay

The latent image will keep quite a while. Just think of all those people who shoot Christmas,easter and Christmas again on the same roll.
Will there be a change? I think that's the wrong question. The question should be can the filter pack handle it?
A couple of years ago I cleaned out the fridge, the desk drawers, the glove compartment, etc. and found 85 rolls of old, exposed C41 film. Most of this film was consumer grade film, witch I understand holds up better in long term storage under adverse conditions. I developed it all at home using Tetenal chemicals, and the bottom line: up to 20 years after exposure, no problems. No serious color shift, no excessive fog, no speed gain or loss. Beyond 20 years I started to see unacceptable color shift, thin negatives, and excessive grain.
Last week I found about 20 sheets of Fuji 4x5 NPS that were exposed 5 months ago and had them processed at the local lab and they were all fine. I had the lab make contact sheets and the printer said they were all good, with no color shift.
don't throw away the expired film. throw it in fixer and extract all the silver, and then send the "waste" to me.
