Brian -thanks for the compliment. As to why techpan, it's a long story.
The room I shot that in is our living room - it has a cathedral ceiling with skylights and is very bright most of the day. So there was a lot of ambiant light. I got a reading of f4 with my flashmeter. Not a lot but enough for what I wanted.
I always wanted to try TechPan out for portraits and that was the opportunity.
Around my house, we have three kids under the age of three. So when I'm working on a family picture project, of which I have a few running at any given time, I usually just set up my camera and light, throw up a background somewhere and see what happens. Usually I'll get something usable. With three kids and a wife, chances are at least someone will cooperate.
