The Strip Technique is a photographic process in which a camera utilizes a narrow slit in front of the film plane to act as its shutter.  Advancing the film behind the slit makes an exposure.  Strip cameras are made to photograph linear or rotational motion.  Invented approximately 170 years ago, this technique was initially used to produce panoramic photos.  Today, it is implemented in photo-finish photography, bullet forensics, industrial inspections, and other means of measuring with photographs.  Slit is an ongoing series of photographs utilizing the strip technique outside its intended use -photographing and measuring the everyday movement often overlooked.
