Ten minutes

It was a typical Washington shoot - the subject is running late (more than an hour), the subject needs to get to his next appointment, we need to try to do this right here in these offices.

But that's fine. You pick several spots to work in, so the designer will have some choices, figure out the lighting for each, and then walk your subject through them. And when the subject is Justin Smith, president of Atlantic Media Company (publishers of The Atlantic, which overall is doing quite well despite being in the hard-hit media sector), you end up with multiple choices for a good-looking cover.
