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.

I know that the vast majority of people don’t own a full spectrum camera like the Fujifilm X-T4 ES, but I have seen a growing interest in infrared since I started posting these Recipes last summer. The general rule of thumb was that extensive editing was required—including channel swaps—in order to achieve good infrared results, particularly for color images. Thankfully, with the right filters and camera settings, that’s just not true, and excellent straight-out-of-camera infrared photography can be quite easy. While the number of people who will use these Full Spectrum Recipes will always be small, I do believe it will grow significantly in the coming months and years—I suspect there may be a small infrared resurgence of sorts.

Also, for those who may have missed it, I added several GFX cameras to the Fuji X Weekly App. If you haven’t opened it in the last few days, you’ll likely notice some changes. There are many more improvements in the works, and hopefully those will be ready in the coming months. While the Fuji X Weekly App has come a long ways since it was first released, it will continue to get better and better.
