In a previous post, I has mentioned the existence of a "new product". Well, AccuRaw is now in a closed beta. AccuRaw isn't of course aimed at the X-Pro specifically. AccuRaw is, as its name suggests, intended to deliver technically accurate raw conversion rather than the "Hollywood colors" conversions that most current raw developers deliver by default. But one part of what AccuRaw does to to give very fined grained control over the internal operation of the demosaic process. Specifically, it has sliders that control artifact suppression in luminance and chrominance, and post-demosaic chroma filtration. So you can tune the demosaic to suit your camera, the nature of the subject, etc, rather than have the one-size-fits-all of the mainstream raw developers.

Of course, this makes AccuRaw potentially useful to owners of camera with X-Trans sensors. So here's a quick comparison showing AccuRaw vs the other guys:

ACR and SILKYPIX versus AccuRaw

In the first crop, set for maximum resolution, AccuRaw gives very good results on the red letters, but has some artifacts. However, with AccuRaw, you can tune the result to what you want. The second crop shows moderate artifact suppression settings - still nowhere near as much chroma smearing as the other raw developers, but much reduced artifacts.
