ISO 800, raw vs. JPEG

At the higher ISO sensitivities, JPEG images don't fare very well. Here, the automatic white balance wiped out the warm tonality of the colors, and you can see noise-suppression artifacts on the clock and sky. There are also quite a few hot pixels in the sky. Shooting raw makes a huge difference at night.
