This is a basic overview of how I work with fur. I've had a lot of questions and hopefully this answers them.
I use about three layers for fur, and constantly combine them so I can use a clipping mask on the whole subject.
There is no secret fur brush-just a regular hard brush with a few setting changes.
After all this, I cannot stress enough about the importance of practice. I didn't learn this overnight, and this tutorial is not to be taken religiously. You may learn a different way, use a different program, different brushes and settings.
Done in PS CS5.
If by chance you use this, don't worry about linking back. No need to, use it and have fun.
