I know this guy is good, but how do you smoke a pipe and shoot at the same time?
Give a monkey enough time pounding at a typewriter, and he'll create an as-yet unwritten work of Shakespeare, or so they say. However, I've been punching shutter buttons for 60 years, and I've yet to create the photographic equivalent, which would be, I guess, an as-yet unshot photo by HCB. Or something like that. Let's face it; the guy was hard-wired for photographic genius. The rest of us mostly just muddle along, but that's OK, too.

He also took decent landscapes. https://monovisions.com/henri-cartier-bresson-landscapes/
