I tried to follow this very interesting tipster by @pandaisdead (www.lomography.com/homes/pandaisdead) which explained how to modify your camera to create half-framed pictures.
Obviously this did not work according to plan and I had troubles when re-loading the film.
But yet I like these in an odd way.
Here is the link to the original tipster
