It seems that CTRL ALT + 2 selects from red to blue and CTRL ALT + 3 selects from red to green.

Depends on which tool is currently selected. Often the number keys represent a percentage (1 =10%, etc.). Using that combination will indeed change which channel you are looking at (turn on your channel menu and press those keys and you will see it change channels).

I'm guessing here, mind you, but I suspect it's selecting the lumnosity of the individual color channels.

I don't know if everybody's keyboards work the same way but in mine when I press CTRL ALT + 1, CTRL ALT + 2 and CTRL ALT + 3, Photoshop selects "something".
I guess that in the first case it matches luminosity with opacity but I can't figure it out what's the other two.Tags: None

by JimmyMJB2So I recently got a bunch of photos with all kinds of problems. I tore through the whole lot of ‘em with little to no problem.
