Early in this thread, Michael A. Smith offered to sell copies of his book, "A Visual Journey" at a discount to APUG folks. I took him up on his offer, and I'm very glad that I did.
I had not previously seen any of Michael's photos, other than on his web site. I like them a lot - and the reproduction in the book is excellent. There is a great deal to be learned from seeing the focusing of his vision - and from reading the essay describing his journey through his photo career.
I've made it through the book once - I'll closely study it for a long time. I'd recommend it to all who are working on their vision.
