I would like to import my Aperture library to Capture One.
Importing the Aperture library is only supported by Capture One for macOS as Aperture is the macOS-only application created by Apple. Consider that Aperture Library has to be updated to Aperture 3.5.1.
What is imported?
Before you migrate your Aperture libraries into Capture One Pro’s Catalogs, you need to know what Capture One imports, and how to preserve the information Capture One does not import.
Image files and versions
Capture One Pro imports all the images in your Aperture Library as referenced images. If your Aperture Library is “Managed” (the images are stored inside the Aperture Library), you need to relocate the original images to a referenced location outside the Aperture Library before migrating to Capture One Pro. You do not want Capture One Pro to reference images stored inside the Aperture Library package directory. Capture One Pro also imports all the image versions as Capture One variants.
- Aperture Project -> Capture One Project
- Aperture Folder -> Capture One Group
- Aperture Album -> Capture One Album
- Any Aperture Projects which directly contain images have a generic sub-album created in CO to contain the images.
Smart Albums, Books, Light Tables, Slideshows, Web Journals, and Web Pages are not imported.
Aperture local adjustments (brushed-in and brushed-out) are not preserved. You will have to recreate them in Capture One using Layers and Layer Masks, which are far superior to Aperture’s brushing in and brushing out. Each Layer with a Layer Mask can reflect multiple adjustments using almost all of the Capture One Pro adjustment tools. Recreating your local adjustments in Capture One Pro should take less time than it took to create them originally in Aperture.
Anyway, here is the list of adjustments that will be imported to Capture One:
- Crop (if not Straightened)
- Black & White
- Enhance/Definition -> Capture One Clarity
- Enhance/Saturation -> Capture One Saturation
- Exposure/Exposure -> Capture One Exposure
- Exposure/Brightness -> Capture One Brightness
- Highlights & Shadows (Mid Contrast ignored)
Everything else is ignored.
- Star Rating
- Color Label (note: Ap Grey becomes Capture One Purple, while purple is imported as pink)
- Applied Keywords (flat, not hierarchical)
- IPTC Core Contact: Creator Name, Job Title, Address, City, State/Province, Postal Code, Country, Telephone, Email, Website
- IPTC Core Content: Headline, Caption, Keywords, IPTC Subject Code, Caption/Description Writer
- IPTC Core Image: Intellectual Genre, IPTC Scene Code, Location, City, State/Province, Country, ISO Country Code
- IPTC Core Status: Title, Job Identifier, Instructions, Provider (Credit Line), Source, Copyright, Usage Terms
Importing Aperture library to Capture One
Relocating your originals to referenced folders outside the library is very important. Capture One does not copy your Aperture originals. It imports your Aperture originals by reference where they currently reside on disk. If your Aperture library is “managed” (I.e. your originals are stored inside the Aperture Library), Capture One will reference them there. If you later delete your Aperture library, you will remove the original files Capture One is referencing. Relocating your originals to referenced folders outside the Aperture Library may take some time if your libraries contain a lot of images. You will need to think through the folder structure you want before relocating them. A good starting point for your referenced folder structure is the organization you use inside your Library. You probably put a great deal of thought into that structure.
As Aperture Library is a catalog, you have to first create a new catalog in Capture One. It is not possible to import Aperture Library to a Session.
Then go to the main menu and select File -> Import Catalog -> Aperture Library.
