I was playing with a telephoto lens to isolate the day lily shooting in bright daylight. It worked well in this case as the background went completely black when the lily was exposed correctly.
I really like the effect!
There is an issue with Uploading Photos (attachjments). I am not sure what the problem is, and I am looking into it. You can still try to Create your Threads and Upload your Photos, but it is hanging up during the Upload.
