Thanks for that. I converted one of the scans to RGB in Photoshop, but that's not the answer. Perhaps that step doesn't really convert, or CO is very picky.
Hi,
Well, as a Raw converter, C1 expects something that looks like a Camera Raw file, or a kind of simple TIFF. So no added layers, no transparency, no strange compression, 3 channels (not more, not less), etc.
So, I just ran a test, producing a scan with VueScan Pro and outputting to a TIFF with profile, one on Auto- and one on No-Compression, and both were read just read fine in C1 version 9.0.2 .
Not that I would normally do that, because TIFFs are huge and will slow down things a lot, and one can exceed the size limitations, or have other non-Raw metadata settings that could confuse the Raw converter. C1 is not an image editor, but it is a Raw converter. However, I can understand some need to produce a catalog that contains the lot, Raw + Derived result after photoediting and Retouching.
So I suggest you review your scan settings. see my settings as attached. Otherwise, open a support case with Phase One, but do read about the limitations for TIFF import first, to avoid wasting their time with something that was already mentioned elsewhere like
here . And don't expect them to have all applications on the planet to test for compatibility, so you may have to supply samples.
Applications that save TIFFs may add their own flavor of previews, transparency, change tags, etc., so it is not guaranteed that C1 will always be able to read everything thrown at it. TIFF is a very flexible format, and C1 is not primarily a photo editor (although it's getting better with Raw based source material).
Cheers,
