Choose a Profile (3D LAB LUT)
Set monochrome character before fine-tuning the light.
Profiles are 3D LAB LUTs that apply a pre-conversion spectral and tonal response. Two colors that look equally bright in the source can separate differently after conversion. The useful question is not “which film name is best?” but “which response serves this photograph?”
The method
Step by step.
- Open Profiles and begin with None — Standard monochrome conversion. Establish a neutral reference.
- Choose a built-in response from the selector. The example uses Ilford FP4 Plus 125 on a dark classic car.
- Compare the body paint, chrome, road, foliage, and sky. Look for separation inside each material, not just a global increase in contrast.
- Keep the chosen Profile, then move to Light for exposure and tonal balancing. Recheck those adjustments if you later change the Profile.
- Use Library in the Profile card to manage installed LUTs. A default can be assigned in Settings → LUT Library; new images otherwise start at None.

At your own pace
Try it.
Compare FP4 Plus 125 and Green Filter on the same foliage-and-car scene, then return to None to check what changed.
Watch for
An infrared-inspired LUT cannot create infrared information that the camera never recorded.
