FILM WINDING & FRAME NUMBERING
IF YOUR CAMERA HAS A CRANK FOR AUTOMATIC FILM WINDING (Hasselblad 500, Pentax 67, Mamiya7, Yashica 635, Kiev 60 …)
Advance the film until the the big arrow is aligned with the corresponding mark that is in the camera’s body. Close the camera and advance the film until it stops and frame counter is at n.1. Now you’re ready shoot: frame numbering is made by the camera itself.
IF YOUR CAMERA HAS A RED WINDOW IN THE BACK FOR FRAME COUNTING (Brownies, Holga, old TLR, foldings, boxes…)
First of all you have to cover the red window with black tape to avoid light exposing the film inside the camera. After the film is engaged, close the camera’s back and turn the film advance knob 8 times (16 half turns) so that the film reaches the correct placing for the first photo.
On 6×6 and 6×7 cameras you should advance the film by 4 half turns for every frame until the film is finished.
On a 6×9 camera advance by 5 half turns. For larger cameras advance accordingly more. Expect some trial and error.
More details and caveats are on the instruction paper that comes with the kit!
