I’ve been obsessed with trying to recreate the look of Kodak Aerochrome, a discontinued color-infrared film stock, for a little over a year now, and I finally got the results i’ve been looking for. Infrared light is not normally visible to the human eye, but this shifts the IR spectrum into the visible range, resulting in some interesting color shifts (most notably, plants, which reflect a ton of IR light, turn into a bright magenta). I can explain the process in more detail in the comments if anyone is interested. I think the unnatural colors make for a very cool alternate view of our very photogenic city.

Another attempt at the Joshua Bird aerochrome method, this time on a camera with much better light seals. Shot on Rollei IR with a Pentax K1000. For those unfamiliar with the method:

red channel: Hoya R72 IR
green channel: Tiffen red 25 + Ice UV/IR cut
blue channel: Tiffen green 58 + Tiffen deep yellow 15 + Ice UV/IR cut
