As I said, there is a world of difference between a 60dpi happySnap and 
a full blown process camera capable of generating a distortion free 1:1 
image for photolithography on a metre by metre sheet of film.

I had a 2MP camera once, It was worse than 35mm 100 ASA slide film.
8MP is where a camera challenges good 35mm film and 24MP is where its 
plain better.

But you need to go a LONG way to challenge 100ASA process film covering 
a square metre/

I am scanning in WWII black and white negatives mostly shot on 100ASA 
film. I need 600dpi to match the negative quality. 1200 is a waste of 
time, 300 doesnt do them justice.

But frankly a page of text scanned at 150dpi is sill legible

Horses for courses. For OCR simply use a camera with a macro lens
