Look a tad over saturated here. But don't believe my monitor.
You might try a bit of reverse USM starting with 30 amount and 60 radius, up or down to pull it out a bit. If you have PS. PSP might have something similar. I know it has clarify you could run a few times on it as well. But haven't got it loaded right now. I have an Image i need to use that on..
Certainly a lot of intricate work in that chapel. I was faced with the no tripod syndrome all over Italy but made do by using pillars and benches to brace my camera against. Thanks for sharing this beautiful image.
Thank you much for the comments.
I'll give the reverse USM a try. That's a helpful tip, I've never tried that before.
I was using 17-55 lens, at 1/15 F.2.8, so there might also be some camera shake. It was extremely dark in there.
