Photography

This motion study was captured with a Zeiss 40mm lens on a Pentax 645Z camera and 10 stops of neutral density. The 13 second exposure was timed so the train was passing in front for roughly half the exposure. The regular corrugated surface of the commuter train worked well to allow the station building to retain detail while still clearly showing the train streaking by in front. A freight train (which passed by earlier) worked comparatively poorly for this.
