I don't defrost film at all - I take it straight from the freezer, open it up and put it in the camera - and I breath on it heavily when I am doing this.

No Joke: I am trying to get condensation damage - and I am very disappointed that I can't.

Has anybody got a slide or negative where they can point at it and say "See, that's what happens if you don't defrost the film?"

Though a little bit of thought and thermodynamics shows why it doesn't happen.
