I recently completed Mike Browne's 7 Building Blocks of Photography, How to Think Like a Photographer. This was a great course, as are all of Mike's courses.
I am now on my 3rd course of Mike's and plan to take another one. I especially like the way Mike teaches---he teaches in a way that I can understand and therefore I can learn from him. His enthusiasm is second to none and keeps me interested.
I have learned the art of "seeing" in this course, which has helped me greatly, and since I spend a lot of time in the outdoors, I now look at my environment differently as a result. I am thinking like a photographer.
Mike emphasizes that the type of camera is not important, it is the person that counts. Highly recommended.
