To avoid color shift when sharpening in RGB mode, sharpen on a separate layer set to luminosity blend mode. I am by no means saying this is better than Lab mode, but it is a way to go about it.
Thanks for this info. I have a book on CS6 by Scott (last name?) & he explains this LAB but you really nailed it here. I enjoy your vids (haven't seen all) but you do go slow enough for myself (some guys talk so fast I slow down the playback speed). Here is a suggestion, how about a vid on importing sky images from my own images? And I'll buy you a coffee. Hope you like espresso 'çause that's what I drink &🍺 it's straight. Paul Labounty, Greeley, Colo. ps. there's so much to learn in PS, I can't get it all but I like these tidbits.
What's funny is after 30 years of using & teaching Photoshop - I'm still learning. The big joke is you never learn everything there is to do in Photoshop.
I opened one of my color images in Photoshop and made two copies, one in Lab/16 and one in RGB/16. I applied identical smart sharpen settings to each, on the background of the RGB copy and on the lightness channel in the Lab copy. Sorry, but I saw no difference in the resulting sharpened image, even when viewed at 100%.
