Oh and a follow -up to my last post, nice pic. I'm with you Graham, I don't invest in alot of photo stuff. You can do alot with a little and still get good results. You can do wonders with inexpensive white board. Once you figure it out, it starts to make sense and you build on that. I've also purchased several inexpensive white photo umbrellas that work quite well.
Key is white reflective material to wash out hot spots.
