The Lomography Splitzer is a masking filter for use with the multiple-exposure feature of the LC-A+ camera (only + version). The two spinning blades within the Splitzer allow this masking filter to only expose certain parts of the picture at once, and then in turn to expose other parts. You can slice an image into halves, quarters, or even eighths. Simply shoot, hit the multiple exposure switch, turn the Splitzer, and shoot again.
This filter slides into the LC-A+'s special front grooves, and will not work with the original LC-A.
