I spend around 3 hours per week keeping up or learning the latest tools/skills.
First week of October I took free Joel Grimmes on-line seminar to pick some new photoshop skills. Joel Grimes, a Arizona based photog, was pitching some new courses he developed. www.joelgrimes.com
I signed up for:Behind the lens, Ten steps to becoming a successful photog, and Texture Background. I learned a lot of usefully information. The Texture background on-line course gives you a lot of basic product & portrait Photoshop Info.
