I appreciate the comments guys - Brian (I asked for hints and you delivered,cheers) and Bob (I almost dozed off at the wheel, so you could have been closer to the truth than you think!). There is still a lot to learn about this amazing camera. It is tricky in dark conditions, as I found out, with more misses than hits. With a torch wedged under one armpit (I needed the D4 button lights), crouching at ground-level, it wasn't easy. But, I at least proved it was possible to take something with an interesting appearance.
