"The slit-scan photography technique is a photographic and cinematographic process where a moveable slide, into which a slit has been cut, is inserted between the camera and the subject to be photographed." from wikipedia

Slit scan is a fascinating technique to create images distortions, a great way to use it is to combine the technique with a motorized turntable (also called lazy susan).

Step 1: Material Required

Webcam, for instance Logitech C920 HD https://www.amazon.co.uk/gp/product/B006A2Q81M/ref...

Step 2: Download and Run the Software

If you are not planning to modify the application download directly the executable for the application (windows)

Or download the source code of the software https://github.com/paul-ferragut/timeSlicer and compile the application using openFrameworks and visual studio(windows) / xcode(OSX)

The application contains a file called settingsCamera.xml

You can open this file with a text editor and change the value for the webcam you are using. You can change the camera resolution or change the camera being used (eg: if you use an laptop with an embed camera set the camera to 0 and if you want to use an external USB HD camera set the camera ID to 1)
