I just finished watching Fundamentals of Photography, a 12-hour course taught by Joel Sartore. It just came out recently from the Great Courses company.
I felt I had to come on here and highlight how informative this class is and how it can greatly influene good habits in photographers.
I love his work. He often gives really helpful tips on the Nat geo website. I have been implementing some of his tips when I go out and practice. Right now I am working on DOF and and manual focus and he had a great tutorial about it on Nat Geo’s website.
