    @janamarie the #RaspberryPi HQ Camera can do UV even below 350nm pretty well, even Video...

    - That uses a #Sony #IMX477 and comes with a C-/Cs-Mount for the #Super8 (1/4") Equivalent Soze Sensor…

    Problem is rather getting good glass delow 385-405nm, because that's the current mass-market limit (due to it being the Wavelenght for #bliray & #BDXL…

      this is so cool!! Taking photos with atypical spectra is a lot of fun, even with the rather old and bulky camera. The imaging technique used here emulates old Kodak Aerochrome film stock. It’s not available anymore, but used to be a colour IR film, which mapped the IR on the blue channel, while remapping red and green to get this pink-foliage look. I do the same here! Blue is solely IR and swapped with the red channel in post. #photography

      @janamarie that is absolutely amazing, poor man's aerochrome

      Would you mind sharing some details on the mod you did? Might do the same thing to my 600D since I kinda hate that camera as is hah

        @nblr oh, yea!! Forgot to mention that in my toot there. Also the specturm is much much wider now, I am pretty sure that you cannot have the full spectrum in focus now

          @mimimitsumii haha, same feelings on the cam. It was my first DSLR, so I didn't want to just 'discard' it (I mean I wouldn't trash it, but give it to someone, but then, it's not a great camera). I followed these instructions https://garyhonislegacy.com/rebelmod450d1.html
          it was simple enough? Although I missed one filter on my first disassembly. Can recommend that mod!

            @nblr @janamarie my Nikon FE lenses had an extra dot (enamelled on the ring) which apparently was used to estimate focus on IR film. I never used it.

              hahaa! Successfully removed all IR and UV filters from my old Canon EOS 600D, I can do full spectrum, UV and IR photography now!

              All of the following photos have been taken with a ~550nm+ lpf, meaning cutting everything under 550nm (blue, purple and uv) off. I love the vibrant pink foliage and dramatic turquoise skies #photography

                  @drj @nblr ooh, right, I remember that!! I'm a bit sad that IR photography kind of went away, sure you _can_ buy IR cameras (like the X-T4) if you work in forensics, but why is there nothing like an Xpro3 camera where you can select to mechanically remove the IR filter and have a proper, artistic IR/full spectrum camera...

                  This used to be more of a thing with film, especially in B&W

                    @janamarie Amazing, reminds me of landscapes in No Man's Sky. I would absolutely live in vibrant pink foliage world.

                      @janamarie Photography can still impress these days! That's satisfying to see amidst all the machine-generated and computer-retouched imagery.
