Loading "finished" 120 roll in reverse?

[aly324]

Hello,
I have a silly question. Testing a camera, I recently shot half a 120 roll of Provia 100F (current version) and then simply advanced through the end without exposing the remaining frames. I know I can respool the roll, but I wonder if I can also simply load the roll in reverse and shoot five frames? Is the ending paper the same length as the lead paper?

Thank you

depends on your camera's loading mechanism too. The end of the backing paper is not taped to the film as the start is. This means with auto loading like on a later rolleiflex model, you will most probably jam your film in the camera as the film will not follow the paper through the rollers but it will curl up somewhere in there.
Maybe not all cameras do this, but i think the chance is big.
Also, the spacing will be counted form the wrong side so when the two sets meet in the middle they will overlap or leave a gap of a random size.

No, the trailing end of the paper is significantly shorter than the lead (approx. 30 cm vs 40 cm). Furthermore, the type 120 film is taped to the backing paper only at the beginning. So you can pull but not push it through the camera.
