You and Me Go Fishin' (For Pictures) in the Dark

Here are a few more sets of nighttime photography in Canada. I did not edit the first pictures on my computer at all, except to convert them from RAW to JPEG. (The second two pictures were tonemapped on Photomatix.) They aren't the best pictures, but I am fascinated by (1) the fact that it was possible to take such pictures in the first place (all around 10 pm; sunset around 7:30 p.m.) and (2) the deep blue color that you can pull out of the sky at night.
