At night:

This was taken with an exposure of 1.6 seconds, F8, 48mm Equiv (30mm lens on APS-C sensor). I'm quite pleased with how it turned out given I used a beanbag "pod" held as tight as I could against a lamp-post to get the image - no tripod due to strict wife ;o)
All I've done in Photoshop is wrap it inside the frame, add the vignette and multiplied a high-pass which has the effect of reducing the brightnes, but adding detail to the edges. Oh, and I'm on a tiny little laptop so can't see this properly - hopefully no obvious crappyness on the image, but you'll forgive if there is until I get home to my PC.
