sessions and catalogs create duplicate images?

Ben Davidson
Hey folks,

I haven't found a clear answer to this question in some of the help, so here goes:

I just began using Capture One Pro for Sony 9.1.1

I tried to create a catalog and then a session of my full unedited photo library (which is about 3TB) but noticed that in both instances, my drive ran out of space. I looked and it appears that Capture One is duplicating all the images. To clarify what I mean- if I create a session of a particular shoot and import those images, then Capture One is creating a subfolder inside the shoot folder, and is duplicating all those imported images. I don't have to the room for that, and I'd rather that Capture One not make a duplicate image since that is a huge footprint. I often shoot 1,500 shots in a shoot, and these are 80MB RAW files. I end up only editing 20-40 images, so if I'm going to use Capture One as an organizing tool as well, I'm going to run out of storage space very quickly if it creates duplicate images.

Am I overlooking something here, or is there a way to create sessions or catalogs in Capture One where the content is not duplicated?

Other non-destructive RAW editors like Exposure X or Lightroom don't create duplicates AFAIK, but instead create sidecar files that store edits.

Thanks.

    In the 'Pro' (not Sony) it basically works as follows:

    You can use a session
    - to browse the folder structure on your hard disk without importing anything.
    - to import images by copying them to a new location of your choice. See 'Import To'.
    Session import has a 'Backup To' option. It creates an additional backup copy on a location of your choice when enabled.
    Sessions create a 'CaptureOne' folder in each image folder to store all previews, adjustments and information.

    You can use catalogs
    - referenced, images stay where they are. See 'Import To'.
    - managed, images are copied into your catalog. See 'Import To'.
    Catalog import has a 'Backup To' option. It creates an additional backup copy on a location of your choice when enabled.
    Catalogs store all previews, adjustments and information within the catalog itself.

    I think the Sony version works the same way.

    Yes. The only difference is that it supports only Sony cameras and RAW formats. Feature-wise it's exactly the same app.

    Just to add a little more information ....

    If you are shooting 1500 images but only wish to select 20 to 30 of them for editing with C1 then you have a few work flow options to consider.

    The Import processes (Session - recommended based on your description - or Catalogue) allows you to select only the files you require from the full set.

    You may find that doing that and actually importing the files as a new copy of the RAW makes sense for you, especially in the session concept. The entire original set can then be hived off to backup.

    Import in into a session also provides some options for setting useful file names and applying pre-sets and styles during the process. Also the possibility for creating dynamic locations if you can make use of it.

    There is a Webinar running (twice - select the most convenient time) tomorrow that will present the use of Sessions as part of a work flow. I reckon it should be interesting and you may find it really helps you to understand the possibilities and options. You can register on-line here:

    HTH.

    Thanks folks.

    I missed the webinar, unfortunately. I've watched a few tutorial vids but I've yet to find out how I can use Capture One Pro to manage the culling process (especially since it looks like it has some handy tools for finding shots that are properly focused) WITHOUT having to import/duplicate the images. I don't have the hard drive space to make duplicates of thousands of 80MB files.

    Can someone suggest the way to proceed using a session where I can view and cull my images in Capture One before I edit, where this duplication that occurs in an import isn't necessary?

    Thanks, and apologies if these are noob questions.

    If you miss a webinar, you can always watch it later on YouTube. Phase One puts them online a few days later on their YouTube channel.
