Tthis is a forum for ps.com and revel. I will move your question so it can be addressed by photoshop people-
Many thks for your reply to my problem about selective sharpening in photoshop CS5.
I have just downloaded the tutorial by Lesa Snider to which you directed me.
If I may ask for more help: What really is a mask? Same as a selection?
I am told that a mask is non-destructive. What means this?
How can I tell if the photo I want to work on is made up of a
single layer or more?
If I mask part of the image, how to create a layer for the
masked section of the image only, that is, NOT for the
How to create an adjustment layer?
What is the difference between an adjustment layer and
a normal layer?
Many thks again from a slow learner!
