I'm wondering could you sort of use thermal paper directly with a lens and a long enough exposure to directly create an image on thermal paper?

#32Why I love Hacker News. I read an article about a cool hobbyist project, and my mind leaps to someone at work was having trouble with a thermal printer... and I just realised what the fix for their problem is...a total tangent but that often happens.
I love the idea btw. My wife wants one already.

#33Makes for a much more in-depth and capable version of the Game Boy Camera + Printer: https://en.wikipedia.org/wiki/Game_Boy_Camera an object of gadget lust for me when I was growing up
I had the camera as a kid. Ben Heck did some interesting reverse engineering on the printer, and there's some stuff on Hackaday too if you're interested.

#34Earlier quoted context omitted.
Polaroid themselves stopped making the cameras and film. "Polaroid Originals" is a Dutch company that bought Polaroid's instant camera brand and IP. They were previously trying to re-create Polaroid instant film on their own, I think (or they'd bought one of Polaroid's film factories, or something?) Anyhow, I think they're the ones producing film now, refurbishing old Polaroid cameras, and also selling their own mode…
Polaroid Originals were originally called 'The Impossible Project' and was a kickstarter campaign based around recreating the original Polaroid Instant film. It ended up being so successful, that they managed to acquire the brand name and IP of Polaroids Instant Camera technology. I'd link to a source, but it seems that https://www.impossible-project.com now just redirects to Polaroid Originals.
They didn't buy the IP for the chemistry for the original Polaroid film though, as Polaroid sold that to Fuji.
That's why there's only 8 instead of 10 photos in a pack, because their chemistry required thicker photos, and the photos take about 30 minutes to self-develop, rather than 30 seconds of original Polaroids or Fuji Instax.

Holography does this though with much stronger lights than regularly experienced.

Why not just take this idea to its analog completion - does an analog light amplifier exist?
Some google searching says the answer is nay. I guess analog amplification of electricity is a lot simpler than light because of quantum effects.

Re: Thermal Paper Polaroid
#36I kinda like the concept, too. Beyond just the whole execution, which is really well done. Thermal paper disappears over time. So this in turn means these photos are somewhat ephemeral. I haven't lived long enough to know whether I prefer photos or pure memory, but I have to assume there's something redeeming about relying solely on your memory. But I also love that my children one day will be able to see perfectly a…
They've been noticeably degrading for a while already in fact, and are getting worse. https://i.imgur.com/Qmmqs3E.jpg
is it possible to prevent or reduce the degradation with a frame or some other protection?

Of course it does exist.
It’s a “light amplification by stimulated emission of radiation” device better known as laser.
Although it can’t be used to amplify the light field in its entirety.

Re: Thermal Paper Polaroid
#40Just a friendly reminder that most common types of thermal paper contain BPA or BPS. You really should be avoiding these endocrine disruptors when possible. https://www.pca.state.mn.us/green-chemistry/bpa-thermal-pape...
