- I had a very detailed discussion with a Kodak rep about Vericolor films and
- refrigeration. It seems that when Kodak produces consumer films they plan
- on a certain amount of shift in color balance over time. They design the film
- so the optimum balance is reached after about 3 months. 3 months is about the
- average time from when the film is manufactured until it is processed.
-
- Vericolor is designed to be at the optimum color balance when is produced. It
- then must be refrigerated to keep it there for as long as possible. The key
- question I asked the rep was, "Is there anything about vericolor films that
- make them age faster or more dramatically then consumer films", the answer,
- "No".
-
- Now for some anecdotal evidence. I recently found 2 rolls of vericolor film
- which had been exposed 5 years ago and left undeveloped under all kinds of
- hostile conditions. The results were no good. The images has obviously
- shifted and the colors weren't realistic.
-
- On the other hand I recently out of sheer laziness allowed about 4 or 5 rolls
- worth of VPS to sit unrefrigerated in my bulk loader for about 2 to 3 months.
- Last night I shot a roll and developed and printed it. The results were within
- 5 cc units Yellow, and 2 cc units magenta, of the last roll I shot 2-3 months
- earlier. Not much of a change.

- All of this is of course FYMI,
