I’ve been meaning to boost my environment painting skills for a while now, so I thought I’d surf around for some tutorials on the subject.
The most efficient method of learning something is to sit at the feet of masters and soak up their instruction. Failing that you could try finding a good educational website.
Ctrlpaint.com is an awesome website and provides just about the best set of free digital painting video tutorials I have found to date.
It is run by a guy called Matt Kohr who is in my opinion a Jedi Master of the Digital Art world.
The short (5 mins approx.) videos are well thought out and clearly presented.
I am currently working my way through the huge list of these tutorials and they are pure gold.
