Migrating Apple Aperture Libraries To Capture One Catalogs

Walter Rowe

For those interested in migrating Apple Aperture libraries to Capture One I created this video that illustrates the process and details what metadata and organizational structure is migrated into Capture One. Here are some notes I made while testing this process over and over again in preparation to make the video.


What Aperture Library information is imported into the Capture One Catalog

  • Image files are imported into Capture One by reference
  • Aperture Color Labels import correctly to Capture One Color Labels
  • AA Color Labels – red, orange, yellow, green, blue, purple, gray
  • CO Color Labels – red, orange, yellow, green, blue, pink, purple
  • NOTE: AA purple translates to CO pink, AA gray translates to CO purple
  • AA Duplicate Versions become CO Variants
  • All keywords and IPTC metadata come over (flattened due to an Aperture deficiency)
  • All ratings come over


What Aperture Library information is NOT imported into the Capture One Catalog

  • Flags – suggest filtering for flagged images in AA and add special keyword
  • Custom Metadata – Move custom metadata field information to standard IPTC fields
  • Keyword Structure – Aperture keyword field does support nested keywords
  • Image Stacks – Capture One only stacks variants of the same image (Versions) – I recommend making an album of each stack if you want to preserve it. Aperture albums are imported as Capture One albums.
  • Books, Slideshows, Light Tables, Web Journals, Web Pages


Organization of Aperture Libraries vs Capture One User Collections

  • CO creates a top level Group (Folder) with the name of the AA Library that was imported
  • All AA organization structure is imported and placed within this top level CO Group
  • Aperture Projects become Capture One Projects
  • Aperture Folders become Capture One Groups (Folders)
  • Aperture Albums become Capture One Albums
  • Aperture nested Folders become Capture One nested Groups
  • CO creates an Album in each imported Project containing all images from corresponding AA Project


How do Aperture and Capture One Differ

  • Aperture associates images with Projects
  • Capture One associates images with Albums
  • Aperture Versions can reside in different Albums
  • Capture One Variants are kept together in all Albums
  • AA Stacks are not retained in CO does not have an equivalent
  • CO Stacks can only stack all of the variants of a single image
  • Selecting a Folder in Aperture WILL display all the images it contains
  • Selecting a Group in Capture One will NOT display all the images it contains


How are Aperture and Capture One Similar

  • Selecting a Project displays all the images in all the Albums it contains
  • Capture One Projects cannot contain other Projects
  • Changing Inspector / Tool Tab panels does NOT change browser/viewer

      Where I live I experience all the traffic of the Washington DC suburbs and the typical stress of large city commuting. I do my best to avoid it by traveling the back roads. Most commuters don’t see scenes like this because they drive the major thoroughfares, always in a rush to get to where they are going. I prefer taking my time and “smelling the roses along the way”. I think this proves it is worth the extra time. What do you think?
      This was taken with my Nikon Z7 + Nikkor Z 24-70/4S + a circular polarizer lens. I processed the image in Capture One Pro 12.
