Lightroom Classic: Support cataloging PSB files (files larger than 2 GB PSDs and 4 GB TIFFs)

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.

Updates to Lightroom Classic, were released yesterday and contain initial support for PSB files.   Please install the appropriate update. You can read more about the updates here.

Note: Lightroom pixel-dimension maximums (65,000 Pixels long edge or 512 MP - whichever comes first) continue to be a limitation but the team is looking into expanding this range in a future enhancement for the PSB file support. 

Thank you for your patience.

Can we, perhaps as a stopgap, have large PSB render/edit in an Enhanced Smart Preview? This preview would be a DNG proxy that differs from a Standard Smart Preview in that it trades out speed for quality. It would be the same sort of smaller render but without a ton of compression/degradation (slower).

(Typical Smart Preview is a heavily compressed, downscaled, lossy DNG proxy, right?)

MANY of my files are gigapixel - I'm looking at a smaller one just built that's 55732 x 23346 px (1300 MP). I don't need 100% zoom on this file, but could use the flexiblity of LR edit tools like adjustment brushes/gradients, etc. Export would apply the edits to the full-res PSB.

You can implement that stopgap yourself. Create your own proxy file in PS, add it to the catalogue, then in Finder/Explorer replace it with the big PSB.

negative. LR throws up its hands.

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.

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.

Thank you, Adobe!  This is THE feature I needed most in LR... the ability to catalog all of my images.  I was losing faith, but you came thru.  Thanks a million! - Jim

Well, it would be great if I actually COULD catalogue all images, sadly the size restrictions are still there... :(

To clarify for others: LR restricts all images, of any format, to be no larger than 512 megapixels and no larger than 65,000 pixels on a side. The addition of PSBs to LR doesn't relax that restriction, but it does allow files larger than 2 GB (PSD) and 4 GB (TIFF).

The size restrictions affect a minuscule percentage of photographs.  I suspect most  photographers photos will be well under the limits and they will happily welcome the addition even with the restrictions.

What’s is the minuscule percentage and how was that percentage value produced? 
It’s odd Adobe can’t fully support their own file format as designed. I’m not going to suspect why that is; I don’t like suspecting.

I hit the limit with the first image I tried. Thanks for the explanation.

This is not enough... try harder Adobe and give us NO restrictions. This is not professional !

Thank you! Took a while, but hey as we say "Ende Gut alles Gut".

As for the 65'000 pixel limit I think this really only affects a very small hand full of people. This converts to 5.5 meters (18 feet) @300 dpi. Modern fine art printers can upscale images up to 4 times which would convert this to be 22 meters (72 feet). So technically you could work on a 22 x 22 meter image (printed) in Photoshop and Lightroom now. Besides that there's no printer that can print this in one go, that's plenty considering the viewing distance rule onto this print in real world conditions.

Off course there might be people that are, rightfully, exceeding this limitation in their work. But hey, that's why we're all called creatives.

I am extremely happy they released PSB support with size restrictions now instead of waiting to accommodate the larger sizes.  They can take their time to remove the restrictions if they choose but this present feature is useful NOW.

They shouldn’t take their time. The new support is great, but for my work I still can’t use Lightroom to get all my images catalogued. Especially since starting to work with the IQ4150 and GFX100 I easily reach the size limit on nearly all of my panorama work.

Yeah, there's always pixel peepers. In life as in photography I always suggest to them to relax and take a step back. I'll do the same here.

Off course I agree that with growing sensors and more and more niche techniques a tool should not limit us. Give Adobe 8 more years and they'll figure it out :)

The viewing distance rule comes from shortcomings in our eyes not our equipment or images. Good eyes can resolve around 60 line pairs per degree. At 12 inches that works out at 572 ppi and at 24 inches 286 ppi.  If you have a printer and driver capable of 1200 ppi (not dpi which are the printer dots which make up those pixels) then go for it, but only the very young or the very close are going to see it.  :-)

That doesn't mean I don't support those folk who want Lightroom to handle bigger pixel sizes. It would be great if we could catalogue all images.

Correct, large prints and close viewing under 12”. Printer is a commercial large format HP ink. (Bumblejax for example).

Now that PSB is supported it's time to add it to the External Editing options
