Question on exported DNG files

    I'm curious why you are exporting DNG and re-importing it? Always work from the camera native RAF file.

    I'm curious why you worry about that rather than about the issue. I wanted to import the dng in Lr to compare against the RAF Lr processing. That turned out unbelievably ugly colourwise, so I naturally thought of finding out what happens on re-importing in Capture One instead. That wasn't much better, hence my post. I hope that satisfies your curiosity.

    The exported DNG will not be representative of the same data that Capture One processes. Opening the DNG in LR won't provide a proper comparison.

    Does LR support the Fuji X100VI camera native RAF files? If so, open that in LR instead.

    LR historically has a reputation for bad processing of Fuji raw files. That is why so many Fuji uses prefer Capture One.

    Regarding the DNG view in Capture One, go to the Basic Characteristics tool and see what ICC profile is assigned. It may have the Generic DNG profile assigned. If possible try to assign the correct Fuji profile?

    Thank you for your reply. I am aware of the Lr/C1 differences in processing Fuji raw files, which is why I'm studying the question, also with other image processing software. I had already tried assigning a Fuji X100VI profile, but none of the the four or five choices given (DNG standard, DNG Tone Mapped, etc) helps: Colours are badly shifted in all of them. Let me add that the Lr-generated dng looks perfectly fine in C1.
    Besides, I think it would interest users to know why exactly C1 produces some exported files that, when re-imported, look grossly different from the original. This certainly doesn't happen with any other sofware and is thoroughly baffling.Another (different) example is with TIFF files.  Here are two side-by-side 200% crops of the original RAF (left) and C1-generated TIFF (right).

    It seems to me that there's a substantial difference in (at least) sharpening, despite the TIFF sharpening being set to zero and the RAF to 160 by default 
    As a side remark, while I understand and appreciate the pedagogic intent, I think it is counterproductive to divert focus on the user's workflow when it is not doing anything wrong.

    Did you check the sharpening setting in the Export Adjustment tool?

    Yes it is the same in all cases.

    So, did you sharpen the TIFF on export or is it set to no output sharpening?

    Thank you for your hints. I hadn't noticed that the TIFF was exported with "Output sharpening for print" (is that the default?). If I set "No output sharpening" the TIFF looks indistinguishable from the RAF, if I set "Output sharpening for screen" it is almost negligibly sharper than the RAF. I guess that settles the TIFF question. Thanks again.

    Hi there, I would like to add similar question to this roll. Why there is a difference between RAF and DNG file (not treated at all) when opening them in C1 22? Original RAF is just taken to DXO PureRaw3 to clean dust. The results of DNG and TIFF compared to RAF look much different. When seen as a preview in Finder TIFF and DNG look same, RAF a bit more saturated. In C1 RAF looks same as in preview, so does TIFF, DNG is much over saturated and shifted in colours. Samples attached. Any suggestions?

    View in C1

     

    and view in Finder preview

    One more question... why is so that TIFF in C1 does not take any lens profile?

    Regards

    Lens profiles are only applied to raw files. That is the way they designed it. DNG files exported from DxO are not raw files. They are linear RGB files.

    Thank you Walter for your answer, I just started to compare them a bit deeper and realised that TIFF and DNG are as you said linear, they do not take any "fuji's" profiles. Just wonder how to put PureRaw3 in the workflow and not loose benefit of having original RAF file (colours, profiles, simulations)? Topaz, which I also have, makes similar changes... have to think about it. Do you have any ideas, did you use PureRaw with C1 and fuji files?
