Jay Mark Johnson is a photographer, architect and special effects designer who gets to play with some cool toys. Recently he had a specialty camera, an $85,000 piece of equipment for taking high resolution panoramas. As explained here, the camera's lens has a narrow slit and captures vertical bands of images that are stitched together into a large panorama. Typically the camera is used on landscapes, but Johnson noticed some strange effects when something moved across the lens, so he stopped moving the lens and started taking timed exposures of moving objects. As he normally would with landscapes, he then stitched all those photos together.
The result is images in which slowly moving objects appear stretched and where quick moving objects are compressed, or only partially visible. Fixed objects are dots of color that when combined become horizontal streams.
Perhaps the same effects could be recreated with a typical SLR by creating a mask for the lens. The troublesome bit would be stitching all the photos together.
Perhaps when I have a spare month or two to experiment. Or when Johnson lets me borrow the camera for the weekend.
