There has been overwhelming response to the latest post about X-Trans RAW conversion; I thank you all for the support and comments!
Since a number of readers expressed interest in how X-Trans files would respond using other RAW Converters, here is an example using Lightroom, Photo Ninja, RAW Therapee and the "official" Fujifilm Silkypix converter. Let me remind you that I only use Windows; I have thus to apologize to almost 50% of the readers that use Macs, because I cannot test Mac-specific programs, such as Iridient.
RAW Therapee is a freeware multi-platform, open-source image processing software, which is making an impression lately. It certainly seems very promising in several respects.
Missing from this comparison, is Helicon Filter 5, because my trial version has expired and is now working with severe limitations. But, from what I've seen, this program is quite interesting in a number of ways and I'm looking into testing it some more. As a side note, Helicon Filter is the only third-party application that I know of, that can also successfully deal with Sigma Foveon files; which goes to show these guys are really trying hard to deliver.
The following is the same shot (with the X-E2 and 18-55mm lens) followed by a 100% crop, processed in series in different converters. Again, a photo with lots of texture and detail was chosen. Files from other programs have been imported to Lightroom (in uncompressed tiff format), in order to normalize for exposure and white balance. The Lightroom version, is directly from RAF, of course. No extra sharpening was applied, except in the case of Silkypix. As I mentioned before, I try to process files in a "real world scenario" kind of way, going for an "optimal" result. Color profiles have been left as each application implemented them, though.
So, here are the different versions, please take your pick and leave your remarks in the comment section. Thank you!
