P: Support cataloging PSB files

Lightroom should catalog psb files, just as it does psd files. I have many psb files that are not over the 65,000 pixels per side or 512 megapixel limits, but are larger than the 4GB limit on psd files, and it would be nice to see them in Lightroom.

    Can Lr team detect a PSB/TIFF that is beyond 512MP and automatically built a Smart Preview DNG linked to the PSB? I don't need any edit controls. Gray out the panel and add an [Edit in PS] button. Right-click the thumb/proxy and "show in Finder" brings me to the PSB. Is Lr/Camera Raw going 32-bit anytime soon?

    Agreed. The bug/feature request for increasing the megapixel limit is in that other thread.

    IMHO, LR doesn't (fully) support PSB and it should fully.Lightroom’s maximum dimensions (not greater than 65,000px long edge and no more than 512 MP). And that's an issue.

    You're hitting the 512 megapixel limit that LR imposes on all imported photos.  But this thread is about LR supporting the PSB format (which has been implemented).  Please add your constructive opinion to this feature request for increasing the megapixel limit:

    While waiting (perhaps a long time) for Adobe to implement this, you could use the Any File plugin to catalog these very large files.  (It's definitely not as convenient as having LR directly support them.)

    I stitch many (30-120 or more) 100mpix files in 16bit together to 5GB- 60GB (or much more)...

    My wish is to catalogue them in LR, not working on them.

    When will this ridiculous situation be solved?

    So here on my desktop (left column) you can see a 60k*40k PSB that I couldn't import into LR, but which I added to a 6k*4k PSD using File > Place Linked. And in LR I'm making adjustments to the PSB.


    As another approach, I changed the PSD's name and fixed the missing file by pointing at the PSB

    Now I have the actual PSB catalogued in LR, so I can manage it, but metadata won't save to the file and I can't adjust it in LR.

    I'd go for the first method, but I just wouldn't hold my breath waiting until there's no need for any stopgap.

    That screenshot was from where? If the proxy file (eg a jpeg, a linked placed file) fits in the size guidelines, it should import and you should then be able to fool LR by swapping over the files. But I am only thinking about managing these files, tagging them, not doing things like adjustments that process the image.

    negative. LR throws up its hands.
