Just wondering whether or not you are intending to add back any film grain to the films, and if so what kind of software or techniques you'd be using to do this. The lowry process seems to have removed most of what was originally there, most probably in order to match the originals with the prequels - seems to look like video in places rather than film. I really liked the aesthetic of the original grain which lent an almost "documentary like" feel in places.
(the lowry dvd restoration of the Indiana Jones trilogy seemed to keep a lot of the original grain in, I can remember reading an article saying Spielberg had requested this)
