Different parts of Antelope Canyon take on different colors as sunlight filters down through the rock. Here, the rock was left with a magenta glow as the camera picked up cool shades from the shadows mixed with the natural orange from the rock. To the naked eye, these colors are barely perceptible, but your brain has a funny way of making everything look the same with its own post-processing. The camera doesn't have this built in desire to make things look a certain way, so it picks up what's really there, even if it's only a faint hint. To me, it's amazing to see a different view than the one my eyes saw in the canyon merely by taking a photograph.
