My school has been given an 8 X 10 Leonardo pinhole and I am curious as to how to properly insert and tension the film holder. Does anyone have instructions and/or experience with this camera? Thanks, Bill Barber
If the 8x10 is the same as my 4x5, there are two rubber covered rollers that are offset to the screw axis. These get rotated till they're tight against the wooden cover that should be included, that sits between the rollers and film holders. Turn same rollers to loosen to insert holder.
