Mr Sandman we have a "local" photographer, who shall remain anonymous, he is an awesome windsurfer who will sit on the beach between sessions and take pics of others having a good time, im sure he is not undercutting anyone, it is a bit hard to undercut something that does not exist, it is not really common to see a pro photograher hanging around our local spots offering his services.
Anyway, our local lad takes awesome pics, and I thank him.
At the same time, I have a buddy that is a pro photographer, he travels the motocross circuit offering his services for a fee, and does well. I dont think the he worries too much about the other few hundred people taking pics! If his product is good folk will buy.
If a pro turned up at a local windsurf spot and offered his services im sure he would get some sales, till that day occurs Im sure my windsurfing buddy will continue to snap away for the enjoyment and personal satisfaction.
