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

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
I also retook a few recent photos in this lovely Aerochrome-style IR! They actually look fantastic, not even sure which versions I like more now.. :D #photography

The camera also is already nutria approved!! Got sniffed and was found to be okay (I think..)

Also, man, water!! The turquoise is just fantastic! #photography

There are some hardships though, since the camera now sees a lot more light (the full IR spectrum), but the light-meter cannot process that properly, auto-exposing is off by about 2 steps. Even worse, with the missing filters and the phase-detect diodes not being in that path anyways, the auto-focus is now off by a tiny bit. You can get used to it, but at first, I was just way off with my focus and exposure.

The resulting images are also very much discoloured, this is because the red and blue channels have to be swapped, which given that I shoot raw becomes annoying. I don't think there is a command line tool to switch two channels in a canon raw-file (.cr2), imagemagick will just invoke darktable.

Using darktable for development would be great, but I sadly have a bunch of bugs with it and my tool of choice is anyways DxO PhotoLab... which cannot swap colour channels -.-

So my workflow right now is to demosaic all photos in DxO, export them as 16bit tif files, then run a batch imagemagick command to swap the red and blue channel on all photos, just to re-import them in DxO for final development. This actually not tedious, just time intensive...

Anymeow, this is how a raw image without development actually looks like. The white-purple foliage is actually neat, maybe I will do something with it as well some time, but for now I enjoy the pink-turquoise style more

@janamarie some of my modern lenses still have the red IR index markers on them, although they are fairly crude compared to the more accurate diagrams on manual lenses I used decades ago for shooting infrared film.
@th ooh, very nice! such a weird artifact in a way
@janamarie I don't have them anymore, but they looked like these manual focus zoom lenses
@th aaaaah yes!! I have a bunch of these barrel type lenses, I just love the markings and interface, even if it is a bit annoying to use at times. Your three lenses are marvelous!
@th oh hey, look at that!! My ligras have them! Now I can do sharp IR projections :D
@janamarie @th
My (sadly no longer) Minolta Rokkor lens had an IR focus index mark.
