Scanning – sometimes I love it, sometimes I hate it. It is usually better than trying to take a photo of a painting though . . . .
I used Epson V600 Epson Scan on one of these; VueScan on the other.
Above was done using VueScan. It captures the colors better but is a bit dark. Below, the greens of the trees and bushes are better captured.
More of the colors show up using Epson Scan, but they are a little too intense.
Sigh.
The fact is that scanning and post-production can really influence how a painting looks. This goes whether the painting is scanned and interpreted using software, or photographed, and then interpreted and adjusted using software. If you look up a painting on the internet and then look at all the images of it, you know what I mean – colors can vary dramatically.
All this techno speak aside, I like them both for different reasons. Both do capture the moodiness of the original watercolor, which I like. Perhaps that is the most important thing – the mood is caught?

Always best to see the painting in person. I like both of these, and am surprised at the differences. Each scanner has its own voice as it were.
Thanks, Fraggy! Pretty funny to think about scanners having personalities – are they authentic??!! Glad you like the picture – I may do it over again to get a better sense of depth . . . .
