I have been doing a lot of research on tutorials for Corel Painter 12 and have found a lot of them on u tube. I have a lot of favorites already.
I really liked Skip Allen Paints http://skipallenpaints.com/
He has tuts that are really nice and very easy to understand from a beginners point of view (me)
Go to his blog and he has some very nice brushes that you can down load for free. (they only work for Corel Painter) He is an amazing brush maker and artist.
On one tut, he explained the pressure of your Wacom pen and how to adjust in a couple of ways, for your own hand.
If anyone wants to post about Corel Painter (12) on questions or answers, you can post here for heads up sites and technics........ they would be welcomed.
I use Inkscape for my illustrations
