Some not so aethetically pleasing, but equally annoying, artifacts can
result if a cassette is opened while still cold in a humid atmosphere. 
Moisture from the outside of the cassette can be transferred to the film
while handling prior to developing, resulting in smudges and fingerprints
on the autorad.
