The Full Spectrum Infrared Film Simulation Recipes are now in the Fuji X Weekly App! If your phone didn’t automatically update to the new version, I recommend manually doing so now (Android, Apple). Because those Recipes are different than those for “normal” (non-infrared) cameras, a lot of little tweaks had to be made to the App in order to display them correctly. It was significantly more work to get these into the Fuji X Weekly App than I had anticipated, but I’m happy they are available there now.
So far, I have published six Full Spectrum Infrared Recipes for Fujifilm cameras: Aerochrome v1, Aerochrome v2, Aerochrome v3, PurpleChrome, Cotton Candy Chrome, and Agfa 400S. These Recipes require a full spectrum X-Trans IV or X-Trans V model. Converting a normal camera to full spectrum is an expensive and invasive procedure from a third-party vendor, such as LifePixel, Kolari Vision, or Spenser’s Camera (to name a few). Otherwise, the Fujifilm X-T4 ES (“Extended Spectrum”) is a full spectrum camera (is sensitive to light outside the visible gamut) 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. Additionally, these Recipes require specific filters.
