Hi, I'm intending to print a 3m x 4m picture for a wall.
It's black and white so a bit of grain is okay.
How many megapixel camera do I need to use in order to print such a size? Do I need a medium format? Or can a 10 megapixel camera do the job?
If lets say, I use a 10 megapixel camera, is there ways to print it to 3m x 4m size? Because I can't get my hands on a medium format camera.
Please offer your advice. Thanks!
