some years ago, i found the following in a quite old (ca. 1950 i'd suppose) 35mm print on Agfa color stock
(see attached pictures).
Notice the "fin" like cutouts at the top and at the bottom of the two adjacent frames, these repeat in every frame.
Cutouts of the same size and shape are also at the sides of the pictures: at the left (next to the analog soundtrack) and at the right.
What's the function of these cutouts? Someone speculated that this was so the DP could see more easily whether
anything that was not meant to be captured (spell: microphone boom) was in danger of getting into the picture.
Also note the three black triangles within the masking at the top of the frames, those are present in every frame
as well. Where do those stem from?
Cutouts at top and bottom of each frame:
Cutout at the left side of each frame:
Cutout at the right side of each frame:
All cutouts are of same size and shape, pictures are not to scale.
