The photographer is using a Canon EOS-1D Mark II, so I guess he's got a Canon flash of some sort, which means he may or may not need to put a snoot on to get that effect.
I last used one while lighting a jungle scene. You can't be me, I'm taken
A snood is a kind of bag for the hair. My mother always called a net onion bag a snood. It evolved to refer to bands around the head and onward into movie use. Samuelson's rental catalogue in the 70's referred to snoods. My crew called them that, from movie use.
But I have to say the snoot etymology is more satisfying. ;-) You can't be me, I'm taken
