RE: filmscanners: exposing C41 for scanning ( was gibberish header)
FYI, I also have a new 8000 ED that has the same banding issue but I am
having a hard time getting upset over it.:) When I do the fine ccd it does
get rid of the problem but when I read the "help" associated with the
button it says that "fine CCD" can add as much as three times to the scan
time. Having a hard time getting upset about that to. Oh well!!
