Inspired from work done by Prof Andrew Davidhazy at RIT, I thought it would be interesting to make a Slitscan matte box so that our photography students could experiment with Slitscan effects in a low tech way.
Box is approx 12inches X 12 inches X 20 inches
Camera is a Canon 5D mk II DSLR 24 - 70mm
The basic technique is to mount the box on one tripod, the DSLR on another. Remove the Front slide and zoom and focus on your subject area.
Replace the slide onto the box, Set your camera on a longish shutter speed such as 3 sec. Press the shutter, move the slide from one side to the other while the action happens.
Then look at your LCD screen on your camera to check your results. The faster you move your slide the faster your effective shutter speed. Moving your slide from up to down position will give you different results to moving from down to up position. Just experiment and have fun!!
