Capture One v7.0.2, the latest version of Phase One's image management and Raw conversion software, includes support for Fujifilm's X-Trans cameras. Given the trouble this non-Bayer design has caused for third-party Raw converters (it remains to be seen how many will ever offer support), this has caused a lot of excitement in the Fujifilm community. So, just how well does Capture One do, and how significant is the problem , in the first place?

To provide some context, the vast majority of digital cameras ever made perceive color using what's known as a Bayer Color Filter Array, named after the late Kodak engineer Bryce Bayer. For its recent cameras, Fujifilm has developed its own color filter array pattern, which it calls X-Trans. The idea behind X-Trans is that its pattern repeats less often than the Bayer pattern, rendering redundant the low-pass filter that usually protects against moiré.

The disadvantage of creating a non-standard color filter array (especially one that took two years to develop the demosaicing algorithm for), is that third-party software makers have to do a lot more work to provide Raw support.

Adobe Camera Raw support

Adobe was one of the first third-party software makers to provide Raw support for the Fujifilm X-Pro1, but the results have not always lived up to the standard set by the camera's JPEG engine, when it comes to rendering fine detail.

In the ACR-converted files, the foliage files takes on something of a 'watercolor' appearance, and the white text of the sign is 'filled-in' green. However the differences in detail rendition aren't pronounced, even at 100%. They become more apparent at even greater levels of magnification but the degree to which this is relevant is arguable. It's interesting to note that this brushstroke effect is exaggerated by applying more luminance noise reduction to files in ACR.

Capture One v7.0.2 - default settings vs Camera JPEG

As you can see, Capture One's color response is much closer to the camera's results than Adobe's default profile. The default results are also substantially more sharpened than the JPEGs are. In comparison with the camera JPEGs, there are hints of the same brushstroke effect that Adobe Camera Raw produces, though not to the same degree and mitigated, perhaps, by the better color response.

It's noticeable that Capture One is less prone to color errors than Adobe Camera Raw, but struggles with the moiré that Adobe appears to be trying to avoid.
