Digital painting has both The Daddy and I intrigued. So I'm gathering up some tutorials. Here's what I've found today.
First, the basics of using Photoshop Elements:
Tutorials from Adobe
20 Elements Tutorials - basic tools, swapping facial expressions, fixing lighting...
A playlist for getting to know Elements: various tools, layers, layer masks...
Smart Filters video Tutorail
So, you know your tools, then you can start looking at tutorials that are specific to digital painting.
The guy that does that has a pretty extensive YouTube channel, and this particular playlist has over 100 tutorials for a whole bunch of different things you can do in digital art stuff.
