By The class. John is the gold standard for teaching. He repairs lessons to perfection. He speaks in ways students comprehend all that he presents. Never waste words. Never bores. Always demonstrates his points. I will continue to purchase his classes as they provide the best learning I have found. He is making me a much better photographer, both technically and creatively. You can't make good images if you don't know your gear. Hope he teaches lessons in Portland Oregon one day. I know Pro Photo Supply would sponsor him.
I have to say I had been disappointed I had to work through parts of this course, it was so good! I purchased it, and going through it again was well worth it. I learned how to do so many of the functions, and when peered with John's Fundamentals, Lenses, and Nature/Landscape courses I think I have been taking much better pictures already.
I do feel that if you have or are planning on getting the D500, this course and the others are very much worth it, and will help your techniques, getting you better photos.
As a amateur "enthusiast" who loves taking sports shots of my kids, I was scared the Nikon D500 was going to me too much camera for me. But after taking this class, I feel a lot better about my purchase and am really excited about getting out there and shooting. John's class is so much easier than reading through a long manual. I wish there was a course like this for every camera I have purchased in my lifetime! Highly recommended.
