Capture One Pro 21 14.4.1.16

Permanently deleted user

Hello,

I have been using Capture One Pro for many years now, having migrated from LR.

I have many images shot with Pentax 645Z from before; I don't have the camera anymore. Capture One Pro 14.4.1 opens some DNGs from the camera, but others do not even show up on the import window and hence, unable to catalog and work on them.

I can't figure out the reason. Would really appreciate any leads on how to fix this problem.

Cheers,

Senthil

    Senthil,

    If you check the Release Notes you will find that there are some constraints about file dimensions that MIGHT be relevant, although if the files are of a typical size I would doubt there is an issue. 

    The other constraint might be images without an RGB colour profile - for example, monochrome images.

    If none of the limitations apply to your image files I'm not sure what to suggest UNLESS the Pentax files changed DNG versions at some point and, perhaps, some versions are not supported?

    Thanks a lot for the comment.

    Yeah, the files are all the same size DNG RAW from Pentax 645Z, with sRGB color profile.

    I looked at the camera firmware. Files from earlier and later dates work but not in between. To give an example:

    Folder 1: Date: 11/12/15 Firmware: PENTAX 645Z Ver. 1.00 ---> Works on Capture One Pro 21

    Folder 2: Date: 2/25/16 Firmware: PENTAX 645Z Ver. 1.22 ----> Doesn't work on Capture One

    Folder 3: Date: 5/9/16 Firmware: PENTAX 645Z Ver. 1.22 ---> Works on Capture One Pro 21

    Camera firmware version 1 files work; with ver 1.22, some files work and others don't. I have no idea what the difference is in the file structure that causing the problem.

    As a workaround, I save the DNG files that don't open on Capture One Pro as TIFF files on Adobe LR, then import and work on them in CoP, but it is a pain, takes more space and organization becomes a problem.

    Any fix would be great.

    Thanks again.

    Cheers

    Any fix would be great.

    Then you should probably talking to Capture One, Senthil:

    Thanks a lot, Keith. I was looking to message Capture One, but wasn't sure how to.

    Cheers,
