Aperture Library Import question

John Quinn
Hello, I'm a very long time Aperture user in the progress of transitioning to Capture One. I have over 10 years worth of images in my Aperture library and I'm working on my strategy to bring them over. In general, my Aperture lib has 4 kinds of files in it: JPEGs with no edits, JPEGs with edits, RAW (NEF) with no edits and RAW with edits. My plan is to export/import by year to keep the number of images reasonable at any given time.

I'm starting with my oldest images, all JPEG files with no edits. I created a new Aperture Library with just these 267 files. When I import this library into Capture One 20, several odd things occur.

1) One of my images (an old photo scanned in greyscale) will not import. No idea why. Other, very similar scans import with no issue.

2) Some of the imported JPEGs have the Red color label applied, this is seemingly random. No color labels are applied in the Aperture library.

3) Some of the JPEGs have the "read only" attribute applied. Again seemingly random.

Any ideas? I'd like to understand these issues before I continue my import work.
Thanks a lot!

    Capture One does not read greyscale images. Maybe other similar images are RGB images.

    2) Some of the imported JPEGs have the Red color label applied, this is seemingly random. No color labels are applied in the Aperture library.
    I have noticed that certain metadata can trigger a color label in Capture One. Not sure this is the case here as well. An annoyance, but easily correctable.

    3) Some of the JPEGs have the "read only" attribute applied. Again seemingly random.
    This may be related to the image size in pixels. Very small images are not editable and get the read-only attribute.

    Maybe you can import the images without edits straight into Capture One, not as Aperture library.

    Paul, thank you. That's some interesting information. Are these known "bugs" or "features" of Capture One? You're right that the read-only issue seems to be related to very small pixel dimensions - but it doesn't seem to be a hard or consistent cut-off. Most, but not all, of the small jpegs are read-only. Many of the other scans that were imported fine were also grayscale, so I don't know if that's the issue or not. As far as the random Red color label, as long as the software isn't trying to tell me something important, it is easy to change (especially as I don't use the color labels in Aperture).

    Thanks again and have a nice holiday!

    It is well known and documented that Capture One will not edit images which have any dimension less than 512 pixels long. Worse, Capture One will not even not even allow the user to edit the metadata - so you can't even add or change a color tag, for example.. I am sure that Capture One has received many comments on this over the years; however they have not changed this limitation.

    I have found two workarounds - 1) Apply a black border using Pixelmator to increase the smallest dimension to more than 512 pixels 2) Use ON1's interpolater to double the size of the image (ON1 trial version should suffice).

    The second limitation is that Capture One does nor process images without an Alpha channel. Many black and white scans do not have an alpha channel.


    Many of the other scans that were imported fine were also grayscale, so I don't know if that's the issue or not. As far as the random Red color label, as long as the software isn't trying to tell me something important, it is easy to change (especially as I don't use the color labels in Aperture).

    Hello,

    We are working on a software solution that will handle migration of Photos/Aperture/Lightroom libraries to CaptureOne. We set the bar quite high in terms of metadata and adjustments migration. Maybe it will be able to help. While in beta phase, we will definitely be interested to get feedback from people in your situation.

    Kind regards

    Matthieu
