That's a pretty good result for a proof sheet! The film rebate is usually the best reference because you know it should be clear film … thereby white if considered a positive, invert to pure black in the actual positive. :)
Fun stuff, I'm glad to see how you're progressing with this technique. It's a nice time savings to getting an reasonable index print so you know where to go for finish capture. (Yes, I don't know how you'd do finish rendering on color work if you're color blind. I can imagine some numerical analyses, but …!! ) onwards!
