As part of the website creation process for my fencing clubs new site I’ve taken several head shots of the coaches.  It’s the first time I’ve used a 3 light setup (having just picked up another 580 EX II while back home), and it wasn’t as difficult as I was expecting.  I think the trick is just to add one light at a time until everything looks the way you’d imagined.  The setup shot is here, where the tripod in the middle is where I had the subject stand.

In this case I wanted to use the colour of the walls in our gym to add a warm, orange-ish background and use a fairly fast shutter speed to kill any ambiant light and make the rest of the image darker.  In this way I could get an orange/black look that would match the colour scheme of the website and I’m quite happy with the results.

A couple of examples are here, and the rest are in the gallery.
