![]() The main reason the DNG file will be larger (assuming same bit depth) is that the processed DNG will contain full color, 3 channel RGB data. "the DNG images produced by Iridient X-Transformer are still quite "raw" and do preserve a great deal of the original RAF image information."Ĭould you talk a little about what is lost in the linear DNGs that are produced, I know you claim that exposure type adjustments can be as effectively done but I am trying to wrap my head around exactly what I am loosing. I have registered the program and it will likely become part of my standard workflow but I do have a question. Depending on personal preferences for sharpening and noise reduction you may want to adjust these settings during the DNG conversion. This can be remedied completely by adjusting controls in the RAW processor in post processing in most cases. In most cases you should be able to apply additional creative sharpening and/or noise reduction to your tastes in later processing on top of this capture stage, but you'll likely want to make some adjustments to the defaults which will often assume no such processing has already been applied.ĭepending on the RAW processor and its defaults some additional sharpening and/or noise reduction may automatically be applied and the result can be over sharpened or have too much noise reduction applied. ![]() The levels of sharpening and noise reduction applied by X-Transformer are fairly mild on there and intended as "capture" stage processing. These processes also can't be undone or reversed without going back to the original RAF. Optionally based on adjustment settings in X-Transformer, some amount of sharpening, noise reduction and lens corrections are also applied to the image data. Assuming you keep the RAF you can always return to the RAF to start from scratch. When you open the DNG into another RAW processor you will get the Iridient demosaic processing and cannot then switch to the RAW processing provided by Lightroom or another program with the DNG. This processing cannot be reversed or undone. This is the process that converts the single plane CFA (color filter array) sensor data (X-Trans or Bayer) into a full color RGB image. Maybe DNG is just not an efficient file format or less suitable for compression.Īt the most basic level the RAW interpolation (demosaic) is "baked in". Seems the X-T2 files will end up at around 70 MB?Įven if the information is exactly the same it depends on the structure of the file. Even with sharpening and noise reduction completely disabled in X-Transformer due to inherent differences in core processing you may still want to make adjustments to sharpening and noise reduction that would be different from the settings you would use with a RAF image. ![]() Depending on your RAW processor you may end up with a case where the sharpening and noise reduction is basically doubled up as many RAW processors will by default treat the DNG images much or exactly as they would a RAF.ĭepending on your own personal preferences and RAW processor you will likely want to make some adjustments to the baseline sharpening and/or noise reduction in your RAW processor, in X-Transformer or both. By default some sharpening and some noise reduction is applied during conversion. It also includes a JPEG preview of the size you specify, for example Medium size of Medium quality.īe sure to take a look at the Help (F1) for details on what processing is performed and the adjustment options available. Stuff like extra sharpening, noise reduction, deconvolution results, color profile, etc., etc. There's more information in that DNG file than in the original RAW file. Probably because the DNGs are already lossless compressed by default, see under DNG options.īut how can a compressed file become larger than an original Fuji file which is uncompressed? ![]() The 7-Zipped DNG file however stays at its original size. This is what it looks like on my monitor (2560x1440, 100% scaling) It's in Settings -> Display -> Customize Your Display -> Change the size of text, apps, and other items)Īny clue why the file size becomes so large? I thought Fuji RAF files were already large by not being compressed, but 7-Zip can bring them down to about 22.4 MB. Seems to be something with your scaling perhaps? Do you have Windows 10 display scaling enabled? Try setting that to 100% as a test. Note also how the window is too small for the text. The actual Settings menu of this beta version seems to offer only resets to defaults, not the options described in the Help? Be sure to take a look at the Help (F1) for details on what processing is performed and the adjustment options available.
