I recently conducted a dance research experiment, formulating a hypothesis to guide a study of the body in 60 minutes. For my study I wanted to use long exposure photography to track movement over time. For my specific research I chose to photograph a small phrase, and then retrograde the same phrase (dancing it from end to start rather than start to end) and take a photograph of that movement. I wanted to see if the two images, one dancing start to finish and the other finish to start, created the same movement picture. And with this study I hypothesized that my pairs of images would look the same. In an earlier post I have created a gallery with the 20 images my study created.
