Lens correction

Boley
I have just recently migrated from Lightroom to C1 Pro and as such have saved a lot of my raw files as DNG. I noticed that when I try lens correction to any of these DNG files that I unable carry out the lens correction yet there is no such problem with lens correction on a NEF file. Is this this the case for DNGs or am I doing something wrong. If this is correct is there any way that I can perform lens correction on DNGs.

Thanks,

Robert

    Robert,
    Nothing you're doing wrong.
    The DNG files you've converted are likely an Adobe Variety that standardizes all the information. As such, the Lens information is not delivered in the way that the Manufacture of the camera intended, and this is the way we have built Capture One to recognize and read Lens Correction information.

    Thanks for your prompt response Drew. Just a couple more questions regarding lens correction and LCC.

    1. Is it recommended or preferred to do an LCC even if you have performed a lens correction. Why is it necessary to use a semi transparent filter to create the correction as suggested in your tutorial.

    2. I have a lens for a profile that I created with Adobe Lens creator for a manual 85mm Ai Nikkor lens that I use. Can I import this profile into C1 and use it it to perform lens correction for this lens. I have noticed that this lens is not in your list of profiles as was not in Adobe's and hence the need to create the profile. If it is possible where are they stored and if not compatible can you recommend a solution.

    Thanks

    Robert.

    You will not get the level of lens correction that you can get in Lightroom and Photoshop with Capture One.

    I also don't see how you could import Adobe lens corrections into capture one as the tools are different or missing.

    Above all you cannot make custom lens profiles as you can using Adobe's free lens profiling tool.
    Your better off doing lens corrections in Adobe, especially for legacy lenses.

    An Adobe Variety of DNG????

    DNG is an Adobe Standard.

    Seeing it standardizes all the information it should be simple to use... or am I missing something

    There are some variations out there, but the Standard one is Adobe.

    Thank Fred, that's interesting I was under the assumption that C1 provided a better lens correction. The comparisons you provided was that a Manual focus AI-S 85mm, F1.4 lens. Did you create your own profile as Adobe does not have that lens in their list. Do you use the LCC function in C1?

    I am interested in your workflow do you do lens correction in LR and then export as RAW or Tiff into C1 and then perform all other editing?

    So again, the standard RAW from the camera delivers the Lens information in a manner we can/expect to read. The DNG does not.

    Thanks Drew,

    Ok, I understand that I need to import files into C1 as raw files if I want to apply a lens profile which is not a problem for future files but what if I have a lens as I stated earlier and it is not in the C1 database. Is there any way to create a profile for this particular lens. In LR I was able to create a profile with Adobe Lens creator software and then store that profile in the database with all the other profiles and then was able to apply it in the LR. Can I do something like that with C1.

    Unfortunately no. the DNG files do not support Lens Correction.

    What sort of corrections are you thinking about Robert?

    For optical corrections where the manufacturer correction values are not available or other test values have not been measured and made available you have the generic facilities in the Lens tool set plus the potential for creating some test files and collecting colour and vignette (etc.) adjustments that can be stored and re-used.

    If you want very specific optical corrections for automatic application at different lens settings as recorded in the EXIF data for a file then there is as yet no obvious way to do that 'at home'. Or at least none that I know of.

    Thanks Grant, I was after automatic correction for vignetting and distortion. I am aware that I can manually adjust this and save it as a preset but I was after something more precise.

    In LR I was able to create a profile with Adobe Lens creator software and then store that profile in the database with all the other profiles and then was able to apply it in LR.


    It would be handy if I could add this profile into the C1 database and apply it there but it appears Adobe and P1 profile files are not compatible.

    For this particular lens I will try importing into LR as a RAW file and do lens correction and then export as a RAW with the profile correction into C1 and continue with editing. Extra steps that I would rather not do.

    Robert,

    You should be able to create an LCC profile for vignetting correction and lighting/colour anomalies in general and that for your specific lens(es) rather than whatever has been tested by a lab somewhere.

    For distortion ... it sort of depends what type of distortion and how pixel accurate you think it needs to be. I think if you are using some of the smaller compact systems where the lenses are designed to rely in software to fix the optical deficiencies then yo might indeed have a problem.

    Fixing an OEM RAW file in some other software and then writing a new version of the RAW ready for a different RAW converter to work with the file in its own way is a new concept to me. Can you point me to a description of how this is done? It's not something I need now but may be useful to read up on for future reference.

    Many thanks,

    Grant.

    Hi, Drew

    I am a new user for C1 pro. I met the same issue on my RICOH GXR system.
    After checking my GXR, i can just choose DNG for raw.
    Does it mean that i can't use Lens Correction function over the raw photos outputted from GXR?
    As i know, the raw file of Leica M9/M240 is DNG type also.
    Thus, this function is unworkable for Leica M9/M240??

    Why C1 pro can't provide manual distortion correction for lens undetectable case?

    As rule of thumb, if the supported camera shoots DNG* as a native format, CO will fully support the dng from that camera (say for the M240 and so on).

    Hi, Christian

    Thanks for your explanation.
    Based on my understanding, it seems that C1 Pro 7 can support Lens Correction function over some types of DNG file.
    But, how i can clarify whether a camera's DNG file meets the requirement of C1 Pro 7 before i buy the camera?
    Can you provide me more information about this?

    This is miss leading.

    DNG files do contain lens information and as such do support lens correction.

    It is Phase One that does not support lens correction with certain DNG files.

    We support it on cameras that are supported and have DNG as native format.

    Hi, Ulf

    As i know, the DNG file of Ricoh GXR camera (with A12 M-mount module) is supported by C1 Pro 7.
    Can you assist in checking why the Len Correction function can not be applied over such DNG file?

    Thanks.

  • Ulf Liljegren
    Just tested GXR with A12 module and this works just fine.
    If it can't be applied it is not a DNG coming of the camera but instead a derivative in some fashion.
    This is constantly one of the issues with the DNG format; you cannot trust that a DNG file is a "Digital Negative" which the name imply.

    Hi, Ulf

    Thanks for your information.
    Under my testing, i found that the Lens Correction can be applied to the DNG outputted from my A12 50mm Macro module.
    But, this function can not be applied to the DNG outputted from my A12 M-mount module.

    Do you have any idea about it?

    I don't know much about the Ricoh system but what I have read suggests to me that the concept of the M adapter is that is will be used with all sort of unknown and unidentified lenses for which Ricoh have no correction information and are unlikely to create any. (A 1940s lens is hardly likely to be able to identify itself for example ...)

    However do they provide some facilities in the M-Mount to make and save settings as you choose to create them? If so is it these settings that may not be applied or for which the, lens identification information is not used?

    This may not work for you.

    I tried this and DNG files exported from Lightroom (with or without embedded original RAW file) do not open correctly in Capture One. Camera is not recognized, colors and exposure are way off beyond correction. Even manually assigning the camera profile does not help at all. Nikon d800 file.

    The Exported DNG file however does open just fine in several other RAW converters I have installed and all recognize both camera and camera settings etc. Also checked the file in an exif editor and it's all there.

    Hi, Ulf

    I don't have any experience of issuing a support case.
    Can you guide me how to do it?

    Thanks.
