Game 16mm B&W neg 1972

I have posted every 100th frame from the film.
Note the marks that appear sometimes till the 4000th frame.

There are about 55,600 frames in the film.

These lines do not seem to cross the frame boundaries, which may give some sort opf clue as to their origin.
It appears to be very clean after that.

I am trying to demonstrate the condition of the film without bias. These frames were not manual selected, just every 100th one.

The processing parameters re saturation gamma etc. were universal for all of the frames. When you select “original” as the image size you are seeing ½ the resolution of our machine.

The processing was programmed for auto-full contrast, which is why black frames are stretched to noise.
