RE: filmscanners: FW: New PolaColor Insight Color Slide profile f or Sprintscan 4000 & 4000+
Wire
The purpose of the new profile is that it should be more robust and give
cleaner (less noise) results when you have a very dark image and you are
trying to pull detail out of the shadows. The previous profile accentuated
noise in the shadow regions. This showed up as a greenish haze. The new
profile produces cleaner shadow detail without that artifact. When scanning
properly exposed slides the results should be the similar but not
necessarily exactly the same as the old profile.
We have a new version that does not desaturate the shadow which I will send
your way.

David, I gave the "Color Slide2" profile a try and found in a well exposed
shot that it significantly desaturates shadows and shifted midtone color
towards the green very slightly; not a color cast, but a change. It raised
shadow levels somewhat in a low-key landscape image. But less so than the
"underexposed color slide" profile.
Would you explain what motivated this new profile and how it works so that I
can understand how to make best use of it?
