Please pardon my butt-in BLOWHARD, but I might be able to save you some time - on the PS commands at least.
FARaveN: The easiest is to learn a few hot-key shortcuts, after a while, terms like those in use here become more understandable. So I'll try to answer your command questions with the appropriate hotkeys, at least you can get the job done that way. ok?
>>>Next "select inverse" and create a new layer for your shadows.<<
Select Inverse= Ctrl-Sh-I and it will 'reverse' the direction of your selected area, so if you have a circle selected inside your square image area, the 'Circle' is selected, if you 'Invert the selection' you would have the surrounding area selected and NOT the circle.
New Layer= second icon from right at bottom of layers palette, mouse over it to read popup tips for 'Create new layer' - any selection you have at the time will NOW affect the NEW layer instead.
>>>Fill it with black or dark brown or whatever. <<<
Use the bucket tool, or, if you have these colours selected for foreground or BG colours, Ctrl-Backspace (key) or Alt-Backspace will fill it using one of those colours
>>>Then feather that selection by 1 pixel. <<<
On menu- go to SELECT/Feather and enter '1' pixel (hotkey Alt-Ctrl-D)
>>>Once you've feathered, clear it out. <<<
Clear it out = hit Backspace key, it will delete the contents of the selected area. (NB: The 'Feathered' action will come into play here.
Hope that helps.
BLOWHARD: Nice tutorial mate, much appreciated.
Cheers
