Walking home tonight I knew I had to get this car with the wide angle lens and some light streaks in the background. However, since I don't bring my tripod with me everywhere, I had to stay really, really still. I imagined myself as a human tripod, and tried really hard not to breathe. And I took the same picture a LOT of times, just holding down the shutter forever with the camera set on burst mode. This technique has saved my bacon a bunch of times.
Focal length: 18mm (on a crop sensor). The widest focal length I own. At a longer focal length the diagonals here would be a lot less interesting.
Shutter speed: 0.8 seconds. Amazing! (The lens has IS. I am not this good on my own. Plus, wide lenses are a lot easier to handhold. But still, I'm impressed.)
Aperture: f/9. This got me those cool light stars in the background.
ISO: 1600. It was dark outside. With my camera, this ISO is a little noisy. But I can live with it.
