OK, thanks for the responses - I haven't forgotten about this thread!
I have some images I took at a workshop 2 years ago that I am going to have a play with. I'll have a look at the hints and tips in the Formal and posed section and see what I come up with.
Portraiture and human studies is something that I have always wanted to get more into (I have the gear and I have dabbled in it). I know I need to upskill a bit when it comes to Photoshop. Now the next hurdle.....finding someone to take pictures of!
