isn't what you just described caused by banding? It's (the colour progression, can't find the word right now)not as smooth as it should be, especially in the very dark corners (very bottom, or at the left) Even the roof tiles (especially the ones on the right) and ornaments look like they are "dirty" because of that. It's as if the colours start to mix up.
you should not watch the movie. It's horrible.Anyone have good sources for the VN or movie by the way before I start picking through torrents?
