The tracks (rails of the Denver metro light rail system) glide by as we head home…
Iâ€™d seen images like this before â€” but via film. I wanted to see what it took to make an image like this with my digital gear. After some fiddling, I found that an exposure of 1/30 second or longer works just fine â€” so long as the train is up to full speed (about 60 miles/hour, or about 95 kilometers/hour).
If you look very closely, you can see some subtle reflections from the inside of the train (since thereâ€™s no way to get my camera outside the window for this image). Iâ€™ll have to spend a little more time in Photoshop cleaning them up. Still, I like how this turned out. The rail tops are nice and sharp, and the rail ties are blurred out, but donâ€™t overlap.
Iâ€™ve noticed one odd thing, though â€” because the rails are at an angle to the imageâ€™s edges, the image always looks crooked to me. I *know* itâ€™s rectangular, but it always looks skewed. This must be some sort of illusion, Iâ€™ll have to look it upâ€¦
