Here is an album with the original stills from the criterion release: https://ibb.co/album/cnXgRF
Criterion were supplied old 2008 transfers, with somewhat blurry and faded look, criterion managed to fix the contrast. They looked also rather brown. I did mostly color correction on these and slight sharpening. There were rumors criterion were searching for actual new sources for these films but Toho shot them down and again, supplied them with a decade old average transfers.
