Thanks for the comments. I have really enjoyed your course, and added lots of knowledge nuggets to use in my photography. In the past couple of years, I've gotten to shoot the grand scenics of the national parks out West, but, I'm most intrigued by macros and intimate landscapes like the toadstools. It was amazing, lying in the wet, dew-laden grass, on toadstool level to photograph what I was seeing. And the longer I stayed there, the more I saw. There just wasn't enough time to capture it all. Any suggestions on what I can do to become better? At what point will I know that my creations are good enough for someone to want to purchase them? I just keep taking photos because I love doing it, but, at some point it would be nice to share them with others, and be able to produce some income to help pay for my photography expenses--especially since I've retired from teaching--40 years in the public elementary and middle schools here.
