    I am migrating my photos from C1P to Lightroom. I am exporting at 16 Bit TIFFs. Problem is Preview won't show them. They display as white, or sometimes black. How can I export these photos as 16 Bit TIFFs for Lightroom?

    My photos are on my old 2013 MBP and I am moving them to my new 27" iMac. So I am trying to export them to my MBP desktop and then copy it to an external drive, which I will then move into Lightroom.

    I am running 10.12.6 on my MBP.

    My settings in C1P are these: File Format: TIFF, Uncompressed, ICC Profile: Adobe RGB, Resoultion: 300px/in
    Scale: Fixed.

    Anyone know of a fix?

    The "fix" is to ignore Preview. Lr can handle 16bpp TIFFs just fine.

    I know Lightroom can handle the 16 Bit TIFFs. The problem is when I export from Capture One I get a blank or black file on my desktop. Will Lightroom read that file? I need to get these photos out of Capture One.

    How do I ignore Preview? I don’t have it set to open Preview. I even tried exporting to my external HD. Still got a blank file on the external HD.

    Haven’t put them in LR yet. I am waiting for my new 27” iMac. So I am back on my old MBP which doesn’t have LR on it. Long story short, I returned the one I had to get a 1 TB SSD.

    Karen, I had remembered C1 and a handful of other tools had the sort of behavior you’re seeing back in the 10.11 and even 10.12 days. This was the workaround they suggested then and which worked for me at that time. Give it a go since you’re still on 10.12. Hopefully it will work,

    Edit: I should add that the "Tiling" option is itself under the compression option in the TIFF recipe.

    Don’t worry if your Mac OS is unable to read the files to display a preview or thumbnail. Just know that the files are there where you put them and that Lr will be able to load and read them when you’re ready.

    Tip: Depending on the total number of images you’re migrating to Lr and the size of the files, don’t put all your exported TIFF files into one folder to import all at once. Break them down into sub folders of a few hundred images each to make the import more manageable for you and your Mac.

    How do you know it is "blank"? If you are judging solely by how it looks as a thumbnail or in Preview then you don't have adequate info. Open the file in a real "professional" tool (read: Not Preview or Finder) and see what it looks like there.

    Thanks for this! It works. Now I can see my thumbnails.

    The way I have my C1P Library set up, I have Collections. So, for example, I take a lot of flower photos. So I have Flowers and then I break it down my year... 2018, 2017, etc. I will import to LR by a year at a time. Thank you for the tip.
