I'm quite familiar with extracting plans from photos. There are lots of fun variables. A couple of times I've had a poor quality scan and higher quality photos. I was able to up Richard Taylors Refit Enterprise drawings that way. The last one was one of the set plans for TOS. Badly folded so I had to cut it up. But no one has scanned it yet so it was worth the effort. The original plans of the Enterprise are gold in comparison. It would be cool to put all the pieces together that exist and align it over the common dimensions of the 33" and 11' models. Shaw did one like that, but it seems there are more pieces than he used.
