CitrusChrome is a brand new Infrared Recipe for full spectrum (sensitive to light outside the visible gamut) X-Trans IV or X-Trans V cameras, like the Fujifilm X-T4 ES (“Extended Spectrum”). It’s not for “normal” cameras. The Fujifilm X-T4 ES is a full spectrum camera briefly offered by Fujifilm to the general public—as of this writing, I believe that you can still buy the Fujifilm X-T4 ES from B&H, but it requires a phone call or in-person visit, and cannot be ordered from the internet. Otherwise, you’ll have to do a full spectrum conversion—an expensive and invasive procedure—from a third-party vendor like LifePixel, Kolari Vision, or Spenser’s Camera (to name a few).
This Infrared Film Simulation Recipe produces orange, red, pink, and peach false colors. What you get depends on the exact light situation and the specific materials—cloth or organic (leaves)—being photographed. As far as I know, none of the infrared films that were sold over the years produced the false colors seen here; however CitrusChrome can be in the ballpark of Aerochrome sometimes, so situationally specific it can be somewhat convincing as an Aerochrome facsimile. What this Recipe more resembles is modern (digital) IR photography, which has a much wider array of possible outcomes. With that said, I don’t believe that I’ve seen this exact look before, so it might be a brand-new aesthetic.

Aside from having a full spectrum camera (like the X-T4 ES), this Recipe requires two filters: True Color Infrared Autumnizer (Turquoise) and True Color Infrared Crimson (Light Blue), which can be found on AliExpress. The True Color Infrared Autumnizer (Turquoise) filter is simply a QB19 Blue filter and LB18 Green filter combined into one, while the True Color Infrared Crimson (Light Blue) filter is simply a QB19 and GRB3 (heat) filter combined into one. You probably could use a QB19, LB18, and GRB3 combination instead of the two True Color Infrared filters, but I have not tested that personally. I was a little hesitant to buy the Autumnizer (Turquoise) and Crimson (Light Blue) filters because I had never purchased anything from AliExpress before, and saw mixed reviews regarding the platform; however (and thankfully), the process turned out to be smooth. I’m not sure if the order matters, but I have the Crimson (Light Blue) filter first (closest to the lens) and the Autumnizer (Turquoise) last (furthest from the lens).

Awesome ! I like this FS recipe very much ❤️ The aesthetic of it please greatly. Well done Ritchie 👌
Thank you so much! 😀
I don’t have an ES enabled Fujifilm camera but you’re adventures with yours, coupled with Dave’s instagram (@twostopovers) instructions on how to easily convert some older point and shoot digi cameras to extended spectrum, has me deep into the world of IR photography. It took me around 15 minutes to open, remove the IR cut filter, close, and start taking IR photos with my Panasonic ZS-7. The hardest part was waiting for the filter “holder” from Ali Express (to date I’ve had good luck). With this little camera, currently using a cheap, adjustable IR 530-750 nm filter, I’ve been able to capture fun b&w images (at 750 nm, reminiscent of Ilford SFX 200) and fun SOOC color images around 530 nm using in camera custom white balance. I am now awaiting a knockoff Kolari IR Chrome filter from Ali Express, but in the meantime am going to give some of my old b&w color filters a go per some of your recent articles on IR photography. Thank you, Ritchie, for sharing all you photography exploits!
Awesome! So glad to inspire your IR conversion. If Fujifilm ever makes the X-T4 ES (or similar model) more readily available, definitely pick one up. It’s so much fun! I’ll look for your IR photos on your IG.
