Before seeing this camera , I was thinking to create a two spool , one slit , extremelly compact 35 mm motion blur camera for street use. I think correct way to create nonblurred image is to balance camera motion speed , film speed and object speed. My other post was suggesting a widelux like slit camera where slit moves on a half circle and film nonstop slides. By this way , it would be possible to use more film to record the image than usual and blurred image would corrected at the computer.
