Robert,
Excuse me please if you already knew this....
thousands of excellent tutorials are accessible thru the internet
One of this forum's "own", has a superb website on PS and PSE. Jay's presentation of material is unsurpassed. He is also an outstanding artist, of whom I am in awe. I'd recommend you surf on over to his site and 'dig in'. We'll see you again come Fall

________you might be surprised at the length of your visit there! A search on Google will also yield tons of PSE tutorials.
This link is just to open the door on Jay's site, it's quite vast.
