DNG export problem

Bernard28
I am quite new to C1, using the demo version at the moment.
I exported an image in DNG format and opened it in Lightroom. It looks flat, dark and greenish. I noticed it was a DNG version 1, don't know exactly what it means but looks quite old.
In comparison, the JPG export is perfect.
Do I do something wrong, or is there a bug in C1 ? I think I noticed a similar remark in the Mac forum ??

Windows 10 , C1 V11.

    Did you export from Capture one using a process recipe or the edit with tool? How did you get it into Lightroom?
    I must admit it I cannot replicate your problem.

    I exported using a process recipe, for DNG there are very few parameters : only DNG format, open with and target location. You cannot specify an ICC profile, but I noticed in the recipe summary an ICC profile is mentioned which I think is the one from the previous recipe. I tried different times but no change.
    I tried once with 'open with Lightroom' and confirmed the import in LR, and once with 'open with none' followed by a normal import (synchronize folder) in LR, all results were identical, ie rather dark, low contrast and greenish.

    Note : I am looking for an alternative to LR, and trying to keep a raw workflow if possible, the reason for exporting in DNG format. I am trying also DXO PhotoLab. I did exactly the same test, the same image, exporting as DNG and the result in LR is absolutely OK, the same as the C1 export in JPG.

    Oops, sorry I must get new glasses I read DNG as PSD for some reason. 🤭
    I am not sure but surely when you export as DNG you are simply copying the original RAW file and making a DNG copy.
    Anyway I did just that and the image that ended up in Lightroom (new to me that open in Lightroom opens the lightroom importer thanks for that tip 😄 ) looked very similar to the unprocessed RAW that was already there.

    Thanks David for spending time on my problem.
    I thought as well that export as DNG could be just a copy of the original raw, but I looked everywhere and could not find a way to export the processed raw, as DXO PhotoLab does.
    I am not familiar with the different variations of the DNG format; I noticed that the DXO exported DNG (Version 1.4) is twice as big as the C1 exported DNG (version 1.1).

    I think it may be because the DXO exported DNG has the original RAW file embeded in it.

    Bernard, I do not think you did anything wrong. This is how it is.

    Out of curiosity, what is it that you like to achieve with the DNG processed into Lr workflow? I asked this because sometimes (former) Lr users are doing this only because they are stuck into the DNG habit (no offence).

    Hi Paul, and thanks for answering my thread.
    As I said, I am looking at LR alternatives, C1 and DXO, and trying to keep a raw workflow as far as possible. I am experimenting, I don't know yet how I am going to switch.
    I don't like the DNG format, I have never used it before, but now this is the way I found to exchange with LR, instead of Jpg or large Tiff.

    Coming back to my questions, you said this is the way ... I don't understand why a process recipe (for DNG format) is just a copy of the unprocessed raw.
    Is it documented somewhere ?
    Is there a way to produce a processed DNG (like DXO) ?

    I have been trialing C1 several times (yes !) , and I like it so much, but every time I find some strange or undocumented behavior that prevented me from switching.
    Thanks for your help,
    Bernard

    Hi Bernard,

    First, when exporting to DNG with CO no adjustments are added to the DNG file. This is by design and the exact reasons are best asked for at Phase One in case you like to know.

    When working with CO, please forget all about DNG. Do not try to attempt to exchange with other raw software on raw level. CO may has it quirks but my advice is to use the original raw file from the camera and put your effort in understanding the whereabouts of CO. There are several great resources on the web.

    Once you are blown away by the image quality that CO delivers there is no way back! 😁

    Forget about exporting to DNG in Capture One.

    Importing DNG is OK if it's the camera native format (Leica, Pentax, Apple, etc) or it's a raw file converted in Adobe software. Other programs like Phase One create DNGs that have no use, IMHO. Last time I checked Capture One DNGs had no white point? So you get that weird green cast that raw converters can't white balance out.

    If you want to roundtrip Capture One with other programs a 16 bit TIFF is the better option. it maintains maximum compatibility and highest quality. Downside is the larger file size. When you send an image from Capture One to another program for editing test to make sure it saves the TIFF in a format compatible with other software you use. TIFF has even more flavours and options than DNG 😄 .
