I'll agree with Bill.
I have two relating questions: how exactly do you ask? and I've seen that your latest portraits have been in the 20 second range, how do they all sit so still?!
Working at a high school gives me access to a wonderful array of students... most of them are my students who are more than happy to pose for me...
When I saw this guy on a scooter fly past me in that outfit, I just stopped him and said "did you lose a bet? you need to come with me - I need to make a picture of this!"
He loved it. I asked him where he got the outfit, he said he bought it on the net. It also had a butt hatch!
I've been working at this school for over 20 years, and have never before combined my photography with my teaching...this work is a joy for me to make...
