Floyd, baby, chill out. "Wild guess" is over the top. I'm a slow typer, I didn't go into a lot of detail about the metering. I do all the stuff in your post here, meter, histogram, Photoshop, ACR (thanks for the link to UFRAW by the way,that looks interesting) I was just checking to see what other methods people used to correct their photos in post processing. > This may or may not be obvious (I live 300+ miles north > of the Arctic Circle); but do realize that I literally > take thousands of images that include snow!

I adjust black point, which retains the highlights. -- W . | ,. w , "Some people are alive only because \|/ \|/ it is illegal to kill them."
