This post is a recommendation: if you think that channels and masks are very difficult to learn, just as I used to, if you think that you will never ever learn it because only Photoshop masters do, visit lynda.com. Why? Because there they have nice titles on this particular issue, all of them conducted by crazy Deke McClelland. Take note:
- Photoshop CS2 Channels & Masks
- Photoshop CS3 Channels and Masks: The Essentials
- Photoshop CS3 Channels & Masks: Advanced Techniques
If you’re not a Lynda subscriber, don’t worry, they have some appetizers there.
