I'm super fond using flour, smoke, anything that doesn't have a consistent form, when it comes to portraits. In my eyes they bring so much more to a photo, it makes you wonder, what is that? How is it done? That right there is my drive, the reason I take photos.
This specific shot is a composite of alot of flour tossing ,it was a super elastic turtleneck shirt luckily so it was enough to just pour half a bag of flour on top of it and then stretch it out and release it - Viola, magic!
I'd have to say that this gentleman's mustache brings it all up just a notch, okay maybe a little more than a notch.
The powder on the eyes makes this shot that much more interesting. =)
