One of my most valuable resources is PhotoshopuserTV. You can download/subscribe the podcast via iTunes. Go to their website PhotoshopuserTV.com They perform at least 3 tutorials per episode. I find their shows to be the most informative and up to date. Check out “The Photoshop Guys”, Dave Cross, Matt Kloskowski, and Scott Kelby. All of whom have published books as well as certified instructors who travel the convention circuit teaching workshops. This show also airs on the Fox Business Network at 1:00am EST. PhotoshopUser is a nationally published magazine, check for it at books store nationwide.
