I have two recommendations. The first one is a recommendation based purely on training curriculum and my perception of "value" - - lynda.com. I was first introduced to Lynda.com when I purchased the Adobe Creative Suite 4 Master Collection. Adobe offered me a "free gift" of my choice...and one of the options was a free month of access to lynda.com. I thought, "Why not?" I was amazed at the volumes of content in their library of flash movies, and when I actually watched the first one (I chose the introduction to Adobe LightRoom 2) I was blown away at the presentation. So...you guessed it, I purchased a subscription for $25 per month, which gives me full access to the entire library of training. Lynda.com has not only Adobe titles, but pretty much anything I could ever imagine wanting to know more about. They have additional subscription levels, too. Check them out!
My second recommendation is really a no-brainer for any photographer - - membership in the National Association of Photoshop Professionals, or "NAPP." Membership costs $99 per year, and also grants members to full access to a plethora of reference materials. But, here is the best part about NAPP - free shipping on all orders from B&H Photo-Video (my personal favorite supplier of everything photographic and computer related). Those of you who know me best will know that I recouped my NAPP membership fee in about three months. Check NAPP out by clicking here.
Those are my two hottest tips for training, tips and tricks, and more.
