I did a search of the forum and did find a mention or two of Thomas Fitzgerald's LightRoom presets for X-Trans sharpening but no separate thread, so I thought I'd start one. http://blog.thomasfitzgeraldphotography.com/2014/02/updated-x-trans-sharpening-presets-lightroom/ I have no affiliation with Thomas or anything like that, but romi.gilles here on the forum had posted a link to his site a while back where Thomas discussed various sharpening algorithms and the improved results he was able to achieve in Adobe products with X-Trans files. I finally got around to trying out the LightRoom presets and I'm finding some very positive results on my own files so thought I'd put up some feedback. The basic gist is that Thomas suspects the X-Trans processing artifacts that show up with Adobe products has less to do with the demosaicing process as most people have assumed, and more to do with LR's default sharpening not doing a very good job with X-Trans files. In fact, according to the blog post, he's seen similar issues with LR default sharpening on A7R files and suggests it may be more of a generalized issue working with cameras that have no AA filter. At any rate, Thomas has been able to achieve much improved results by setting LR sharpening to 0 and doing the sharpening with a more complex process in Photoshop. The presets for LR aren't quite as good of a final result, but are designed for users that want to stay in LR without adding in PS (you can count me in that group, I dislike needing a multi-step editing workflow when I can avoid it). I tested the presets on some photos of my own and I can definitely see *much* sharper resulting images, without hitting ugly artifacts like I would just using my standard sharpen presets that I use for other cameras. Very pleased with the results so far, and would love to hear feedback from anybody else that gets a chance to try them as well.
