The “problem” with our vision is, that our eyes adjust their irises to brighten shadows and lower highlights automatically. When we look at the grassy foreground, the irises open and the grass appears brighter. When we look at the sky the opposite happens. Our brain remembers exactly that: brightened shadows and a darkened sky, which makes our memory different than what our camera has taken. The histogram of the memorized image would look like the HDR histogram added above by @Wolfgang.
