Sorry, Joboy, didn't mean to by-pass you. That's what happens when I race through the threads.
Thank you so much, Ken! I appreciate the encouragement. I think we all have our days when we wonder if we're making any progress at all. I have a friend named Ken who is also a photographer, does digital art, and lives in the UK. I had even asked him if he were Cameraken, but of course he isn't. Small world.
