I have digitized family photos from a tintype in 1880 or so all the way to Polaroids from the 1960's and it is clear to me that peak consumer-photography was late-stage B&W photography.
I shouldn't have mentioned the tintype above (I just wanted to indicate the temporal range here) because I would exclude professional "portrait" photos. And my relatives were blue-collar farmers and factory workers in the Midwaste, so their "gear" was modest for the times.
The oldest "home photos" look poor and likely came from a Brownie or similar. But then a decade or so on and the photos take on a whole new level of clarity and sharpness. That level of quality persists until the arrival of color, Polaroids....
It seems we traded color for quality sometime mid-Century.
