So then the followup to this thought experiment is: If an expert from our time could go back 500, 1000, 2500 years and create a piece of modern tech, then *what* prevented that culture/location from figuring it out? There really isn't much in a camera but, nobody made one.
Take a camera: People have been making glass for a long time, and you can just find glass anywhere there's sand and lightning or heat. A box. Yep, that's not hard. Pinhole cameras were known for a long time. Paper? Wood? Film, now *that's* the tricky part, but, just a camera?
Well and Camera Obscuras are from ancient times. So at some level “they did” is the short answer not involving film.
Right but you're missing part 1: The most MODERN tech Going the FARTHEST back. You're saying you can go back thousands of years and invent a tech they already had. I'm saying, I might be able to go back to 1500 and make an 1830s style camera.
Nah, I've heard that same kind of Ayn Rand fantasy that only a wealthy society invents things. If that were true then nothing would be invented since everyone was poor in the past. The confusion is confounding invention with mass production.
There are several alternate history stories that explore exactly this. Man goes back in time, changes civilisation. Gunpowder is the most quoted example that has a profound impact.
LOL...impact.
I imagine without film, a camera is a useless box. Oh, and there's the whole " Necessity is the mother of invention", and most folks were in societies where (if they weren't the ruling class) they were just trying to stay alive. Not much room for much else.
