Is that Damien Maia in the grappling pic? looks like him. I took one of his seminars a year or so ago. Awesome guy.
It sure is, I got to shoot a seminar he put on in Vancouver. Got to go for dinner with him and chat for a few hours, very awesome guy and he's fighting tomorrow night.
I've been very fortunate to shoot some MMA personalities in my short photography life.
Here's Dana White (actually got to know him pretty well, despite popular opinion one of the best people I've ever met):

Bellators Daniel Straus and Renato Laranja

Justin Wren and Renzo Gracie:

Frankie Edgar

John Danaher

Sorry for hijacking the thread haha, there are a few low shots in there 
Cheers
