When I lower the camera, to adjust its light sensor to the lake,
hillside and hotel, the blue sky becomes white.
Can't get the camera to capture both brightened foreground and
blue (dimmed) sky in a single image.
The human eye doesn't actually do much better, but it does it
dynamically, not statically. It adjusts the light sensitivity
to different parts of the scene as you move your eyes, and
constructs one mental image that shows it all to best effect.

My friend Ed Bacon tells me that some modern cameras and phones can achieve this effect via an HDR (High Dynamic Range) setting that instantly captures over-, under- and proper-exposures and then blends them into a single image with expanded dynamic range. I checked my Android Samsung phone and sure enough, it has an HDR mode. Nice! I should have used that for this picture. If only I'd known.
