Hi , I am new with this topic thats why don't be scared if I asked some very strange question ;-)

I have scanner with ScanSoft OmniPage SE and MP Navigator .
I would like to scanned some books and transfer them to pdf format : saving pictures in this way , but for some reason it make the whole pages as pictures in pdf format which is quite big as a size at least .

Any idea where to find Tutorial explaining like how to save them without loosing detailes .

Thanks !
