It's similar to going to ski camp for skiing, you'll get out of it what you put in. I was in whistler during the exposure camp last year and everyone had a ton of fun and the coaches said it went well. I didnt see any videos really but it seemed to be a pretty good time, lots of video based activities and lots of really experienced people helping you create a video. If you can afford it, its definitely worth it.
I went last year. Probably the best week of the year. The fact that you get to learn under Blake Jorgenson, Darren Rayner, and Jonny from PBP justified the cost itself. The fact that I go to shoot Wallisch, Kenworth, and Woods was amazing. Go, you won't regret it.
