I was happy with ACR only until I started using C1 on my X-Trans files. For me the difference between the latest ACR release and C1-8 is like day and night. C1 is sooooo much better, image quality wise. There is more depth in the image, more color variations in my landscape images, better noise handling, more neutral colors.
Hi Jaap,
Capture One is reported by many as in general providing superior Raw conversions, and also better than most for the Fuji X-trans sensors. There may be a few smaller converters that sometimes equal or even improve on the results for specific cases, but those may then then less full featured on other aspects, or only available for specific OS platforms.
I’ve read that C1 profile all the cameras the support so there is no need to color balance your images with X-Rite or something, only grey balancing.
Well, all converters need some sort of profiling, because reconstruction of color from a Bayer CFA mosaiced set of data is part art and part science, with many trade-offs. The X-trans sensors uses yet another type of mosaic, so many Raw converters struggle to get good conversions from that. Apparently the C1 conversion has been very well received by users of cameras with that sensor type.
Capture One uses a different type of profiling (more Scene referred ICC profiles, than output referred like Adobe uses). Both can produce reasonably good/pleasing results, although again it's not an exact science because a lot of subjective/aesthetic choices are involved, like more pleasing skin colors or more pleasing landscape colors. Phase One usually creates quite pleasing general profiles, sometimes even several tuned ones for each camera model. Capture One Pro then additionally allows to modify such a profile with its Color Editor, and save that as a new ICC profile for later use. This allows to tweak the color response for specific shooting scenarios where accuracy of some colors is more important than for others which might get less accurate. It's allway about trade-offs, so nobody has a perfect solution.
They also seem to do noise profiling so the default values are pretty much on par.
I think also others do that, but I rarely (if ever) use the defaults anyway. I typically start without noise reduction (saved as a camera default), and I then handle issues, if any, as they may present themselves. For certain uses of images it may even be better to not use noise reduction at all, because it tends to reduce resolution, and when you e.g. downsample if becomes much less visible anyway and helps to prevent posterization. There are some extremely good dedicated noise reduction alternatives that may be a better choice in general, although Capture One also offers e.g. single pixel noise suppression that may come in handy when alternative solutions do not have such capability.
Cheers,
