One of the top three films that I’ve had requests to make a Film Simulation Recipe for is LomoChrome Purple, a unique color negative film released in 2013 (and updated at least once since) that has some infrared characteristics despite not being an infrared emulsion. On regular Fujifilm cameras, it’s not possibly to emulate the film straight-out-of-camera (it would require some extensive editing), but how about on a full-spectrum infrared model? Well, it’s still not quite possible (as far as I’ve so far discovered) to accurately mimic it, but you can get in the general neighborhood.
To be clear, this PurpleChrome Recipe is IR, which means that it’s for full-spectrum infrared cameras like the Fujifilm X-T4 ES, and not “normal” cameras. You must have a full-spectrum X-Trans IV or X-Trans V model, which requires an expensive and invasive procedure from a third-party vendor; otherwise, the X-T4 ES (“Extended Spectrum”) is a full-spectrum camera briefly offered by Fujifilm (it’s very difficult to find, but in my opinion totally worth owning)—I believe that you can still buy the Fujifilm X-T4 ES from B&H, but it requires a phone call or stopping by in person—you can’t order it from the internet.
PurpleChrome is not my favorite infrared Recipe, but it can be fun for unique results. In the “right” situations it can be a convincing LomoChrome Purple facsimile, but much of the time it is divergent enough that it’s not going to fool anyone familiar with the film. It’s surprisingly decent sometimes for nighttime or indoor photography, but it’s great for turning vegetation false-color purple (for best results, use in sunny daylight situations). This Recipe requires two filters: Hoya G(XO) Yellow-Green filter and Tiffen Yellow 2 #8 filter. I don’t know if the order matters, but I have the Yellow filter closest to the lens, and the Yellow-Green filter furthest.
