Craig, Mic, Greg, Mark and Marco, thanks for the feedback. These orchids and the ones in my other post were my better images. The others I haven't posted are a bit cluttered with many orchids jammed close together, lots of little labels and name cards etc. It was a competition after all.
I like the black background on flowers Mic. I got the idea from looking at another member's sequence of shots. Can't quite remember who it was but I think they had a previous history into inverted things.
Oh, I nearly forgot, I need to improve my sharpening skills. You can see hallos on many of these shots. Any advice in this area would be appreciated.
