Old Photoshop Books (Newtonhill AB39)

I did the Ooen University Digital Photography Course 15 years ago. I am thinking of going through the course material again - If you don't use it, you loose it. The supplied software still works but I am getting to the stage of life when I would like extra explanations. Anyone who is interested in what my wife calls "digital trickery" can contact me for a chat. Photos are example of lap trays that I recently designed.
