Too bad about those color bars not being on the CLV, but the caps look great -- those colors coming through will make the Blu-ray color-correction shine! Maybe althor1138 can post his color bars with a couple of full spectrum screenshots to act as a Rosetta Stone? The Criterion laserdisc looks to be consistent throughout (see the following test adjustment). Then you can adjust your captures to match with a single setting.

In that regard, I tried a quick brightness (gamma) & contrast (midtones expand) on ld_comp_1.jpg:

Very nice. :)

BTW, http://s21.postimg.org/7r80easzb/ld_comp_2.jpg is not coming through for me. ld_comp_1.jpg, ld_comp_3.jpg, and ld_comp_4.jpg show fine. Postimg.com appears to be a little flaky. I've seen this problem before. I wonder if it's their "s21" (server21?). Could you upload ld_comp_2.jpg again?
