Now that's interesting. I never thought that it would take so long to
warm up. I usually start scanning as soon as the software will let
me. As you know, if you've looked at any of my slide scans, I do have
a problem with a red cast, or RSGs (red scanning gremlins) as Rick
calls them.
It's just like monitor calibration. Nearly every calibration utility
tool includes in its instructions to be sure that the monitor has
been on, not sleeping, for at least 30 minutes before attempting
calibration. I usually let the flatbed or negative scanner sit on for
15-20 minutes at least so that the lamps and the sensors stabilize
temperature.
