Italy with an E-PL1
First shot was a 13 second exposure, f8. It was quite a bit darker than my picture makes it seem. Nothing special about my settings or mode. I think I using aperture priority for that shot. I tried to keep it at f8 since the Olympus 12mm is great from f4-f8, ISO100 to minimize noise. I was using a small tripod I carry around with my gear which is about half a foot long, so exposure time/shake wasn't an issue. I'm not an expert by any means but I was just playing around with long exposures which are fun at night.
