What I was going for was as wide open as I could aperture to let as much light in and keep as much out of focus as possible - except what I was focusing on, in this case Big Ben tower, fast enough shutter as being hand held I didn't want to have anything blurred, but not too fast that I needed really high ISO which introduces noise. I think I got away with it mostly.
Got to say without the magazine and it's tips, I probably would not have tried this kind of shot, or wimped and used the semi-automatic P mode.
