The use of camera movement and/or zooming during a long exposure is a technique I learned from one of my photographic heroes, Bryan Peterson. It takes experimentation to figure out which photographic subjects are likely to produce interesting images.
So a while back, I decided to try out this technique in an urban setting, namely central Edinburgh. I was quickly intrigued by the many colourful tour buses going by.
The images in this post were taken with an exposure of 1/8s, turning the camera while holding the zoom ring. It takes quite a bit of practice, and I had to try my luck on a lot of passing cars and buses to get the three images you see here. I really look forward to trying this technique on other urban photography subjects.
