finally I got some results, showing the first test-shots with an Eclair Cameflex 2-perf.
I shot a shortend of b/w in magazine#1 and some color-stock in magazine#2.
After developing, the film was scanned in 4k (full-frame, perf to perf).
Both the shots show a kind of double-exposure instead of an accurate frameline.
Masking 2.39:1 is alright, although I don't know what is actually being cropped, of what has been shown on the ground-glass before (unfortunately, I did not shoot a frameleader).
But, masking 2.35:1 leaves a small "light bar" top and down, when centered vertical correctly and using the full width.
Question: Is this phenomenon normal for a 2-perf Cameflex, due to its transport mechanism? Or is there a need of adjustment? If yes, where an how? Magazine's pressure-plates?
By the way, the image is satisfying steady.
