Each pine tree in the forest stakes out its own space in the canopy, with only the tiniest channels of light between them.
Rolling hills (in this case, outside Park City, Utah) normally vanish into Rayleigh-scattered blue haze. (That was particularly the case this summer in Utah.) The magic of a red filter for black and white photography is to simultaneously reverse both the fading and the bluing effect. The result are landscapes like this that seem to go on “forever”.
