I guess it comes from my filmmaking background: I've always been fascinated by how movement can be portrayed in still photography. For this series I, shot in London in 2016, I was using a Fuji X100 T, a small (but not simple) digital rangefinder with a fixed 23mm lens (35mm equivalent in DSLR terms). Over the lens was a B&W (German) ND 3.0 filter, reducing the light to the camera's sensor by 10 f/stops. This forces the camera--or the photographer if using manual exposure--to shoot at a longer exposure. In the galleries it was around 2 to 3 seconds, while outdoors it was more like 1/2 to 1 second. All handheld; basically a still version of the "shakeycam" so beloved of cinematographers.
