really disappointed 1 3

I am extremely disappointed with this scanner that responds poorly to my hopes. The picture quality is about right but we can get even with a printer / scanner means. Slides lose all their colors and we can not do much to improve this situation. When the negative pictures, only newer can be resumed, the largest old photos can not be treated due to lack of adequate support. Maybe there are solutions but the user manual is so succinct that we can not really expect to find something.
