cell phone images (IMAGE)
Caption
Cell phone cameras adjust the brightness of a scene using a single value, which explains why the sky is overexposed in the top image and the ground is underexposed in the lower image. The eyes of flies and humans, on the other hand, can generate stable responses to contrast even when there are changes to background luminance.
