Hoya R72 - infrared photography 📸

25 Jun, 2025

I do not recall where I first read about it but I have had the idea to try infrared photography with my Fuji X100F camera. it's been the most fun camera I've ever had and wanted to breath a little new life into it as I'm trying to rekindle some creativity.

All digital cameras can record IR light but have filters specific designed to filter out as much of that light as possible. So... you can modify your camera - open it up and carefully remove the filter all the while not breaking any of the important tech you want to keep working... OR, you can use filters to manipulate the light getting into your lens.

Something in the design of the Fujis, though, still let through more than typical amounts of IR light which means that you can filter out the visible light spectrum and pretty much crank up the exposure to gather enough IR light to get a photo.

I just got the filter last week and am having to re-learn how the exposure works but this looks like it'll be pretty neat.

Look! Infrared light is red.

Much of the impact comes from channel mixing which allows you to "recolor" various tones within the IR spectrum you capture. That's what leads to some of he really neat cotton candy colors you see ion foliage in some IR photos.

Ultimately what I took today was really under exposed which didn't allow for good color gradation/differentiation in the mixed channels but the fact that I got this with an inexpensive filter and hand held¹ is really dang cool.
