Excellent points. I’m glad someone with more knowledge than I could weigh in here.
I’m not sure how the kinograph is currently set up but I think that you’re suggesting capturing 3 monochrome images per frame which would significantly slow down the digital capture process. I’m also curious about the cameras people choose to use for this task. My guess is that we’re still well below Ken’s 75MP low watermark.
I’m in agreement about degraded film stock and poor initial quality material you mention.
I’m going to guess that within the next few years someone may well develop and OpenCV app that finds its favorite of the 24 frames and generates a composite image it likes. It may already be usable to remove spots and other artifacts during the digitization process. I’ve only fiddled with OpenCV briefly but I’ve already been impressed with what it is capable of for converting B+W images to color.
With regards to lost digital content…
I’ve lost no shortage of hard disks in my time, so I certainly feel the pain there. I’ve also had drives that somehow crush raw cr2 files. Presently I try to back everything up in at least two locations.
