Thanks for looking, Ling. Vuescan produces a scan that is quite low
in contrast, which is better than the opposite, so I could probably
still improve the images and work with several images to improve
contrast. The profile just gives me a limited starting point, so I
don't follow it slavishly other than that. Kodachrome is notoriously
difficulty to scan with the Sprintscan, for some reason. I'm just
trying to get the scans into the ballpark, so to speak.
I don't have a color histogram once leaving Vuescan, but I did notice
that I have needed to pull back blue in a number of scans. I have to
do some increase of saturation to get the correct impression of light
intensity in many cases, including 123. I agree that one is not quite
right. I also did some perspective correction on that one as well.
I work up the images in AdobeRGB and convert only for web images.
Perhaps there is some issue with that as well. Thanks for the
feedback.
