Does the belinograph need syncing though? I imagine you would just have a waste ribbon around the photo and start it after the call with say a delay you both agreed too. Or maybe you could send light in some known pattern with a starter strip and the receiver could look at the lamp.
Attenuation most have been a problem though? I guess you could send some sort of calibration photo to adjust gain? I don't think practical FM signal modulation was a thing yet in the 30s?
