I need to accurately photograph mood boards. These are large (4x8 feet, 120x240 cm in my case) white or black boards with photographs, material swatches, pantone swatches pinned to them.
The goal is to have the ability to re-print them elsewhere (we have offices on 3 continents that need to use these boards) so that the prints are a reasonably accurate reproduction of the original ones.
I can't scan these boards (too large) or make multiple copies (too much work).
I can easily take multiple pictures, and color-adjust them and stitch them together automatically, but I'd like to have to take as few shots as necessary.
Good hints are here, but I'd probably like to have a higher resolution.
Are lenses a good way to achieve that, once I've maxed out on camera resolution?
