It's not the light or the boots - it's the context they fit into. Sometimes an image just cannot stand on it's own without surrounding context - which could be words or associated photographs. Sure, if you want to get all fine-arty about it, then yeah "here's a picture of a pair of boots in the desert, complete with foot trails across the dunes." But that's artificial.
Stop worrying about grain, resolution, sharpness, and everything else that doesn't have a damn thing to do with substance.
