Why are my presets greyed out?
Lightroom presets will appear in italics and be greyed out when the presets are only partially compatible with the image you are currently editing. The most common scenario is when you are editing JPG or PNG images and the presets are designed for RAW processing. In many cases, the presets will still work just fine.
If you are editing RAW images and a preset is still greyed out, it may be because the Adobe profile is not available for the raw files from your camera. All TPA presets currently use standard Adobe profiles that are compatible with all cameras that Lightroom can edit!
