ON1 2022, DNG embedded profile not used when opening

    RAW files, including DNG, does not have any colorspace assigned to them because there isn't any color in them. The profiles that are in them are for the jpeg previews.

    When you open an image for editing in Photo RAW it applies a Camera Profile to it. That is just a LUT applied before any of your processing. The Linear RAW option tells the program to not apply the LUT and display the unprocessed RAW data after assembling it into the color image you are looking at.

    Not having any Camera Profiles specific to the camera is one of the reasons I've stopped using DNGs and use the cameras native RAW files.

    This I understand - color space is different thing - a table. However in those DNGs (BTW Huawei phone) there is Camera profile embedded (describing not only how colors should be assigned globally to certain color space but even how they should be interpreted/processed based on their location in image). And this image profile is understood by LR 6 and Zoner photostudio but not by ON1. LR reports that input camera profile as Embedded. Any idea/experience with this type of info included in DNG? BTW Silkypix, Rawtherapee or Topaz studio do not understand it either.

    This is a question for tech support and the engineers, sorry. I don't know any more that what I've already said.

    There is a lot of leeway in what the camera manufactures can put into their EXIF data. When they start doing non-standard things it requires custom code in all the different RAW processing programs to handle that custom data. Not all software companies will be willing to put in the resources to handle each and every one-off thing like this.

    There are other discussions on both these forums and, if you're a member, the Plus forums, that discuss the program's handling of EXIF data that you might want to look up.
