are you going to inform people that your a commercial business and will be charging them for their pics? Or are you just going to keep positing that you will be there in hope that people don't know that they have to pay??

I don't know kitesurfshot at all but I spotted a photo of myself crossing the finishing line in the L2L race a few weeks back and enquired if I could get a hi res copy, I was waiting for the cost but kitesurfshot sent me that one along with a few others FOC.
I received a couple of good quality photo's and would have happily paid a few dollars for them however to receive them for free was very refreshing and if I was considering a dedicated photo session I would be contacting kitesurfshots.

At the prices charged I'd say she is definitly not in it for the money (at this stage at least) but just to try to recoup some of the cost for the equipment purchased to do something she obviously enjoys doing.

Win win in my book.
