Interesting concept - Definitely could identify with the three contestants - having not dabbled in studio work myself, I'd be just as intimidated....but I reckon I'd enter just to play with a 'Blad !
I thought the host wasn't overly convincing though - not bad ...but a bit er.."beige" for want of a better description.
As Rick said - be nice to have more instructional info.
Also I'd have liked to see the pro do his own take on the three subjects - how would he shoot them.
