Side effects of NOT refrigerating Pro film - consistency?

[jsb]

I understand the benefits of refrigerating film. On the other hand I

am curious if all film of a given batch of unrefrigerated film would

shift evenly and consistently, roll to roll?

 

<p>

 

Let me put it another way... if I put 25 rolls in the fridge and put

25 rolls on top (unrefrigerated) of the fridge and let these 50 rolls

sit untouched for a few months, would the rolls that were not kept

cool "degenerate" evenly? I'm thinking that if 25 rolls of

"Professional" film is left sitting at room temperature over a period

of two months that all of the rolls should color shift evenly and

consistenly. If they didn't it would indicate to me an instability

in the emulsion, thus an unstable environment refrigerated or not.

Perhaps I'm reading too much into the care and feeding of film...

Speaking for negative emulsions two months at room temperature would

hardly effect Kodak Pro films like VPSIII or Porta. Fuji pro neg

films like Reala, NPS and NPH are prone to slightly more drift when

not chilled.

For transparencies, you have three emulsions that age

at different rates. So I think that the effects of

aging will not affect the emulsions exactly the same

way.

 

What "aging" is is chemical reactions going on and on-

going as film sits unprocessed. The effect is not that

bad. That is I keep my film in the freezer. However I

often have film in my cameras for months before it is

developed. To me the results look ok.

 

If however someone was paying me $2000 a shot to meet

deatlines at a specific quality level, I would make sure

I was using emulsions of the same age and properly

stored, and used asap.

 

Depends on what you require for your work.
