Scientists Found a Way to Make Infrared Light Visible to Humans

- cratermoon 4y agoThis article makes it sound like they invented infrared photography[1], but they obviously did not. The paper linked is simply about a different and novel way to do it with mid-IR. The press release claims it's cheaper, but of course infrared-sensitive film has been around a long time, and some digital cameras can do infrared. Although Kodak discontinued their infrared film offering, Rollei[2] and Ilford[2] still make it. Edit to add: the paper also talks about IR wavelengths beyond the sensitivity of current consumer technologies and film; that's novel, too. 1 https://en.wikipedia.org/wiki/Infrared_photography https://en.wikipedia.org/wiki/Infrared_photography 2 https://www.rolleianalog.com/rollei-infrared/?lang=en https://www.rolleianalog.com/rollei-infrared/?lang=en 3 https://www.ilfordphoto.com/shooting-infared-extended-red-film-guide/ https://www.ilfordphoto.com/shooting-infared-extended-red-fi...
- h2odragon 4y agoMy wife can see a bit more infrared and ultraviolet than most people. She describes patterns in flowers that others cannot see and can see "mirage dazzle" in what others perceive as clear air. It throws her notion of color off from normal, too. She's always calling things "yellow" when i see green and similar. I'd love to be able to have a glimpse, even through a camera filter, of some of the things she sees.
