I've been a member of NAPP for many years and the two most important reasons I remain a member are their excellent magazine and free shipping from B & H. As a member you also have access to a website with a huge amount of tutorial information. While searching for Camera Raw tutorials I came across this selection, which is only a small part of what's available. When you join ($99 a year) or renew you will receive a DVD of Photoshop Hot Tips, which is a nice perk as well.
