How people behave in early calotypes, daguerrotypes always strikes me as hugely informed by the shutter speed problem: you need them to hold a pose long enough to register an image. Now ask yourself, how "naturalistic" is this going to be?
I mean sure. People smashed down handfuls of spag. But, I bet they also didn't routinely hold it for 5 minutes en masse.
Side note: Early calotypes of Scots Fishwives capture an image of strong working women in amazing multi layer skirts. What they don't capture is the raw, unfettered, frankly disgusting tongue which went with it, It should not be a surprise there is a saying "to swear like a fishwife" -So "to eat spaghetti like a street urchin" could be a thing too.
You make a good point, but going by some cursory research (starting with [1]), it seems to me that while initially daguerrotype portraits took 10-15 minutes to expose, several innovations had reduced the exposure time to well under a minute by the 1850s. (The earliest photo in the article is from 1873, the most recent is from 1903.)
