correction on previous post: ZeroImage is the other way around!!!!
Bert I'm having trouble imagining how this could work! Does the 120 film travel from left to right in a ZeroImage camera? I've never seen one, so maybe I can't imagine it.
Hi Ned,
Good point. Almost any camera transports film from left to right (when looking through the view finder). I tried to make a simple drawing to explain my way of thinking.
Take the first shot of situation A-B, transport film from left to right, move the camera to the right and make the second shot of situation B-C.
Since most pinhole cameras (or a Holga as well) have fully manual film transport, you can wind the film too far or too short. This is prevented by centering the frame number excactly in the middle of the window. This I use to my advantage by misaligning the film on purpose.
The trick is that the image you see is inverted inside the camera: left becomes right and right becomes left on the negative. With a normal SLR yo wont notice this, since the view finder corrects this effect with a prism inside the finder. But when you ever used a 4x5" camera you know what I mean.
However: the ZeroImage camera seems to be the proverbial exception: IT TRANSPORTS FROM RIGHT TO LEFT. (I just checked my ZeroImage 6x9).
So for this kind of camera it is just the other way around: Shoot situation B-C, transport film from right to left, then shoot situation A-B.
Thanks for the correction!
