OK, another tutorial and I got this as a result:
The tutorial covered the film effect and the drop shadow was part of the tutorial that resulted in the orchid. It took quite a while to do this one, I wouldn't describe it as an easy tutorial, but although it was technically difficult, PS Hero really does have the knack of simplifying things. So thanks again mate, I really do enjoy learning new tricks.
I was looking at his site earlier and he has a great tutorial for improving photo's - I might do one over the weekend and post a 'before and after' so that you can see the difference.
