I went to a seminar recently and asked if I could take some photographs from up the back. I did so with a biggish white Canon lens, which was technically a good idea and I got a few photographs which I thought were quite good, but I think it might have made it a bit too obtrusive. No one complained but I got the feeling that people were a bit uncomfortable with it.
