The main thing I learned is that I really need to get a quality light meter. I also learned that there is a huge difference between a professional model and an amateur.
The class also provided a tone of advice how to direct subjects that are not professionals. This will be the most likely scenario for me as I want to take photos of people that are actual shooters in stead of models.
The class also addressed various types of release contracts as well. All great information.
I got a college degree in photography in 1980 and I am amazed how much of the info I have retained.
I am also amazed how much people will pay for camera gear when they are just doing it for fun.
--I guess you can say the same about me with guns.
