He has always been clear and unflinching in his reviews and comments, so I trust him as much as any online-authority I am aware of. Although he is now an ambassador for Hasselblad, that is relatively recent, and I have followed Ming Thein for years. This article also appeared here.Quote from: Michael Erlewine on January 21, 2017, 06:26:40 am For me, the handling of color is more important than most of the rest of the physical differences between the X1D and the GFX, this early out. You can find more of his work on his website, Instagram, and Band Camp.

However, Darktable is not interpolating around the phase detect pixels as it should for this sensor technology, although these single-pixel errors are unlikely to be noticed by all but the most critical viewers. Iridient applies some additional post-processing which cannot be disabled (or is perhaps using a joint-demsoaic/denoise algorithm), while Darktable leaves absolutely all noise reduction, sharpening and other filtering to the user’s discretion. The algorithms employed by Darktable and Iridient produce extremely similar output (so similar, in fact, that they may even be the same underlying demosaicking algorithm). This image was then post-processed through Darktable, applying the same color profile, basecurve, and sharpening (none) as the other images to permit pixel to pixel comparison.ĭarktable’s output was generated by processing the RAF file directly with the Markesteijn demosaicking algorithm (3-pass mode), 2 iterations of false color smoothing (chroma median filter-this amount selected to match the appearance of false colors in the Iridient image), and no sharpening.

Iridient output was generated by Iridient X-Transformer (which produces a demosaicked RGB DNG file, not a re-mosaicked Bayer image as is commonly believed) with the following settings: Detailed, Sharpening Off, Luma NR Off, Chroma NR Off, Lens Correction Off. Visual acuity varies as widely as does opinion on the significance of detailed image analysis. Have a cup of coffee (double espresso for me, thanks).Įven with these prerequisites, I’m sure some percentage of you will be squinting at the screen and wondering what the heck I’m talking about. Note: Darktable, dcraw, UFRaw, RawTherapee, and perhaps other Free RAW processors, all use Frank Markesteijn’s algorithm for demosaicking X-Trans images, so similar results can be achieved with any of them, but we’ll focus on Darktable here because it is, in my opinion, the most capable and mature, and the program I use the most personally.īuckle up and get ready for some crops! Put on your reading glasses if you need them. In this article, we will explore the differences and similarities as they relate to image quality, in particular the quality of luminance detail. I don’t have access to Lightroom and therefore cannot provide my own example of its output, but a simple Web search will provide you with more than you need to confirm this assertion. Iridient has become a popular alternative/adjunct to Adobe’s Lightroom for FujiFilm X-Series camera users who wish to process RAW files, due not so much to Iridient’s excellence as to Lightroom’s inadequacy in desmosaicking X-Trans images. Several commenters suggested that I could get better results from a commercial software product called called Iridient Developer (which, it should be noted for those yet unaware, cannot be installed into your FujiFilm camera’s firmware in order to improve its JPEG output). (I also pointed out the compromise between color detail and false color/moiré inherent in X-Trans) I showed how, specifically in terms of color detail, Darktable was able to do a better job than FujiFilm’s own processing. In my previous article on the difficulty FujiFilm’s X-Trans sensor has preserving fine color detail, I used the free software Darktable to process the RAW examples.
