I learned a lot about retouching in Photoshop lately. I bought a bunch of tutorial-DVD's of respected Photoshop professionals, and seeing their workflow actually on screen is by far better than just reading it in magazines and books.
One example is this self-portrait that I just did within half a hour with several layers, masks and filters, and a technique called 'Dodge&Burn' by Calvin Hollywood. It shows the PFlight presenting the latest trend in MTB freestyle-fashion (I mean the beanie, not the glasses...) according to a big Japanese cycling-company.
