Actually, I joined the forum to read comments from photographers who use RF cameras. After reading through some of the messages, I thought you all might be able to help me. And I really do appreciate your help, and have read through all the comments.
As I said, I'm not a great photographer and don't know nearly as much about it as any of you (nor do the other members of my team, obviously, given the comments on our survey design!) But we chose to study about cameras because it was interesting to all of us and something we all had at least some experience with. We've definitely learned a lot.
I'm sure many of you will probably find our conclusions trivial or wrong, but the point is less about accuracy (at least for me) and more about learning and experiencing a new world. Thanks to all of you who helped!
I'll post the link to the final project after June 2. Since I am reading your comments, any other insightful input you might have is appreciated!
