I think the art captures feeling much better than photos could. From a technical standpoint, Harding could use colors however he wanted to, and is not limited to black and white like combat cameras would be. However he still chose to stick mostly to grayscale. Also, while photos would be somewhat distorted because of the technology, they show only what the camera captures. Harding includes tiny details in his pictures, but he still makes them fuzzy and a bit blurred--how I would expect a sleep-deprived soldier to see the world.
