Has anyone attended the Nikon School courses, and if so, would you be willing to share your impressions of them? I'm looking at Introduction to Digital SLR Photography and Streamlined Workflow Techniques. If you took either of these courses, at what "level" of photography were you when you took them? Did you feel they were worth the money, worth your time? Have you read books or found online resources that provided the same information the courses did, or did the experience of working with the instructors provide something more than you can get from a book or online tutorial? As a relative beginner, would I be in over my head with these classes? I've had one very basic photography class through community ed, and that's all. The cost of the courses and the time commitment are tough for me, and I'd really appreciate hearing about others' experiences. At this point I'm leaning toward taking them, and I guess I want to hear either 'yes, they were invaluable to me' or 'no, if you go buy these books and read these articles you'll get the same info for less money, with no travel involved.' Input, anyone? And totally OT, I just ran a 5k tonight! Years ago I all but destroyed my knees and shins with lots of street running, and I'm just now working my way back....ever so slowly....to being able to run again! So excited I just had to share!
