I've been using Iridient Developer for RAW conversion to TIFFs. This has seemed to be the best alternative, as it was much better (to my eyes), than LR. However, I have been using Luminar more and more to further process the photos because of all the additional flexibility and presets. Tonight, I was playing around with an image that I want to print fairly large, comparing the TIFF from Iridient to a direct RAW conversion from Luminar. I have to say it was a toss up. I'm wondering if anyone has noticed a big improvement in Luminar RAW conversion of X-Trans files with the 2018 version of Luminar. I think I did a similar comparison awhile ago and thought Iridient was much better. Thanks for your comments.
