    So are you trying to send the retoucher all the original RAW files or the resulting HDR combined files?

    If the combined HDR DNG files, have you already made edits to them?

    If you want to have the retoucher start at the beginning of the process then I would be tempted to make a session for all of the original files with their edits and send the entire session - assuming your retoucher knows C1 and has a version compatible with yours.

    What are they asking for and how does it relate to the work you have already done? I'm just wondering if there a might be a simpler solution for what you wish to achieve.

    Hi SFA, thank you for your insight. 

    I shoot artwork and exhibitions, so the color and tonal adjustments that I make on set are critical. I need to send my retoucher a set of HDRs from an exhibition. I've created a custom icc profile for the shoot and have made global adjustments correcting for uneven light and color casts. 

    I would just send the entire session, but depending on the project it can be in the 75GB+ territory. I need to just send the HDRs with the .icc profile and adjustments I made on set.

    Hi Gerald,

    I will start by saying that I have never looked into using icc profiles with HDR merge processes.

    My guess would be that the icc file for each image might need to be unique although that might depend somewhat on how the different merged frames have been created  - i.e. the way the different exposures have been defined and whether that would result in different adjustments for each image.

    If the question then becomes one of identifying how the merge might handle those adjustments or whether a single icc profile could be applied to the resulting merged DNG file. I suspect maybe not, but I am guessing when I write that.

    Most of the data size will be the original files, the DNG merged files and the .cop files. The .cos files are usually quite small. Have you used any layers and masks?

    I doubt there is a way to significantly reduce the size of the data set you need to supply. Sending the merged DNGs but not the original pre-merge RAW files would help for the size and, in theory, if retouching the DNG content the original RAWs are no longer significant. However, if the original RAWs actually offer some point of reference that the retoucher can use for comparing results  - such that having them available would help - then you may need to make them available anyway.

    Some sort of file-sharing service would be the way go despite the storage capacity required. 

     

    If you could, theoretically, do without the original RAW files would that make a big enough difference to the problem without compromising the re-toucher's ability to do what you need to do?

    Thank you again for your very generous thoughts on this, I appreciate your time. I am all set on applying the .icc profile to merged HDRs. It's a complicated process that I finally cracked after about a year of tinkering. I have very beautiful and consistent images throughout the shoot. 

    My retoucher has no need for the individual RAW files. They just need merged and adjusted HDR files. 

    For example I have a session with:
    - 100+ RAW images bracketed ±1 stop
    - 20 merged HDR files, processed and edited with layers + icc profile

    How do I get those 20 HDR files to my retoucher along with the icc profile and the edits I've made on set?

    I suppose this is maybe a bit unconventional but it seems strange that I can't pack the HDRs as an .eip. That would solve the issue.

    You write that you are working with Sessions (i.e. NOT a Catalogue) 

    In that basis you may already know that the all of the edit information is saved in folders within the session folder structure. Specifically the folder that contains the source image will also have a "CaptureOne" folder which then contains 2 subfolders ("Cache" and "Settingsnnn") which contain the necessary supporting edit instruction files, previews, and a few other things if used.

    The .cos files contain reference paths to to any .icm (.icc) profiles used since it expects them to be available somewhere in the system. Usually the color management options in the OS but potentially elsewhere if, for example, you have created you own and saved them. They will be saved in the "User Settings" related to the username you are using for that computer.

    So for the image (DNG merged file) and any edits made for it one can simply move it to its own folder within the session folder structure or a folder you create for all of the images you will send to the retoucher. The concept of the "Selects folder" with a shortcut key available, might be useful. The Image and all related files will be moved to the specified folder. 

    Once that folder is ready to send you should be able to copy the folder complete with subfolders and send it off. The retoucher, given a compatible version of C1, should be able to open that in a C1 session.

    Note that the default naming conventions for some of the sub-sub folders can be versions and even release number specific so if you and the retoucher have different versions you might need to check for compatibility. Backwards compatibility should be OK.  I.E if you have on older version of C1 than the retoucher. 

    It is likely that you will need to manage any .icc/.icm files that you have created if you use the simple "folder" provision method as outlined. Creating and addition folder and copy them in should work. Probably best if the naming convention helps to identify which file profile goes with which image.

    The eip creation would normally deal with that but I vaguely recall that there is some sort of techical constraint that currently prevents such packaging technique being applied to DNG files. 

    It occurs to me that there is a possibility that importing the "Selects" folder collection to a Catalogue might automatically add any local .icc/.icm files and everything else to the catalog (A Managed catalog would include the "original" DNG files) and might be an equivalent to an eip file in that respect - but without compression and some aspects of portability across machines with different operating systems. But I'm not sure about that and in any case, I suspect it would not be helpful for your file size concerns.

    SFA,

    Thank you again, that did the trick! I moved the HDRs to the selects folder, then copy/pasted the files from the selects folder to the capture folder in a new session. Then zipped the entire session and sent to my retoucher. Worked perfectly. 

    Much appreciated!

    I'm glad you have found a solution that works for you Gerald.
