As most of you may know, David Hockney enlarges his famous iPad drawings to fit enormous walls at the Royal Academy, london.
Does anyone know how to increase pixillation or a file size to the extent he does so that he can print them at huge scales without graininess?
I am not a techno person, so the answer needs to be in lay persons terms.
