I would like to be able to print pictures as big as 2*3 meters. How many MP do I need..? I tried to use a formula I found but I got 850 MP (seems a bit futuristic for now).
Okay I found this formula MP = (print area in square inches) × 23.6 ÷ (viewing distance in inches)²
Here
So if you got 850MP you wanted it sharp at a viewing distance of 16inches?
1 meter you probably need to be scanning large or medium format negatives because you need 140MP
2 meters you get 35.4MP which a D800 can do.
3 meters viewing distance you're to 15.7MP which you can do on your Olympus.
