I'm still using ISO 50 for those long exposure shots on my 5DII. I've experimented with 160, 200, and others, but I just find that any other ISO gives me noise and also seems to lack the same level of richness and depth. I dunno. Maybe I'm just doing it wrong
Thanks! Both shots were 30 seconds, simply because that's as long as I think the 5DII will go without resorting to Bulb mode, and I never seem to have my remote shutter release with me when I'm out and about.
What can I say that hasn't already been said! Love the second shot. Mind, if I had a restaurant called Bankers Hill I think I'd change it in these troubled times!!
