Seeing the trailer has convinced me, that Raiders really needs a shot by shot regrading. However, to do this I need a reference. Since there are no prints available, the early laserdisc releases seem like a reasonable starting point, using the WOWOW as the source, since it has the most detail, and the least issues.
The process will be to first match the WOWOW to the laserdisc, and then correct the gamma, and contrast. The first tests indicate the colors will be quite different from both the bluray, and the WOWOW.

I will run a test first creating a video based on a clip I found of the early shots of the 1984 laserdisc, and if that looks good, figure out how to obtain a digital copy of the entire film on laserdisc.
