I was waiting for this quick-moving train to pass, so I took a picture of it, moving the camera with the this car as I exposed the image. It took me 30 tries, but I got this good one. To get a slow shutter speed, I closed way down to F22. Panning is a good technique; you should try it!

Source image. I think there’s some dust on my sensor, but I’m not going to try removing it because it only shows up at small apertures like F22 here. I cloned it out and added some nice colors and contrast. The sky is over-exposed, but I don’t mind it here; seems to match the movement of the train somehow.
