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.

I've got a large number of photographers and retouchers using my PSB Quick Look plugin who regularly create PSBs with 15 layers or more (the recommended method of doing non-destructive editing with Photoshop). They start with high-resolution images and all those layers cause them to exceed the 2 GB PSD limit and the 4 GB TIFF limit:

50 megapixels * 6 bytes/pixel * 15 layers = 4.5 GB

I'd still love Adobe to implement this. It is LONG OVERDUE. Any compositing with more than a handful of layers with 30-50MP shots will hit the 2GB limit for PSD very quickly.

It is a shame Adobe won't explain why this problem hasn't addressed.

There is a work-around, however.  You can create a linked one-layer Smart Object file, save it as a TIFF and import the TIFF into Lightroom.  Sean Bagwell has a good video on it on Youtube: A BETTER Way to Save HUGE Image Files in Lightroom

This reply was created from a merged topic originally titled Please add PSB Large Document Format Support in Lightroom.

Higher resolution cameras are becoming more common. I layer my photographs from medium format cameras, resulting in files 4-17G. Lightroom's lack of support for large document format files means that I have to create complicated workarounds. Adding the ability to catalog the files would make my life much easier.

Thanks!

This reply was created from a merged topic originally titled LR Classic Can't Read .psb Files??.

Trying to add my composites and paintings to Lightroom Classic (latest version), but it won't read .psb files. Is this correct? Adobe can't read it's own files still, or am I missing something here (wouldn't be the first time)?

Correct. LR does not read large document files. It should, though

Yes, it should read PSBs, no question.

Grasshopper is patient, but would like to hear from Adobe that this feature is on their development team's roadmap.

They are not going to tell you, unless you work for them or test for them. When it's released, you'll know. Until then, be patient.

For a Radial/Zoom blur filter having realtime preview we are already waiting since 2004...

For those looking for a workaround, Sean Bagshaw has posted an update on his approach using Smart Objects.  This version uses a linked smart object -- a more effiicient approach.

nice, Adobe finally listened to their Lightroom users:
with today's Lightroom Classic release 9.2 PSB files are supported!
(and it really works (just tried it))

Like all files within Classic, the maximum dimensions are 65,000 pixels on the long edge or 512 megapixels. So it’s a start but it doesn’t fully support PSB.

Well the size limit is still there... not usefull for me at all.

You mean saving it to a PSD file? Yes, that is still limited to 2 GB. If you open a file from Lightroom, make it grow beyond 2 GB and then save it, you get an error message telling you the file is too big.

However, I just tested by opening a raw file from Lightroom. I copied the background into 40 layers or so and then saved it as a PSB file, amounting to 8.92 GB. Lightroom shows that PSB file in the catalog after the "Save As" action, didn't have to do anything like synchronizing the folder. So yeah, for me it works and I'm delighted.

No, I’m talking about psb files larger than 512Mp.....

I would be already happy, it Lightroom Classic did show up PSB files. If you must save a PSD files as PSB file because it's > 2 GB, this will yet never again show up in Lightroom Classic, even not after synchronising folder. And that's kinda ridiculous...

Hmm, I observe different behavior that appears correct:

1. In LR, select a raw and do Edit In Adobe Photoshop.

2. In Photoshop, do File > Save As and select Format: Large Document Format.

3. Observe that the saved .psb appears in the LR catalog stacked with the original raw.

If you're observing something different and undesirable, post in detail the steps you're taking and what's going wrong.

This  is definitely a step in the right direction, but I see some problems. Primarily, files must be saved with "Maximize Compatibility" checked. I guess this creates a layer that LR can read and use as the thumbnail and as something to edit in the Develop module. HOWEVER, this adds quite a bit to the file size. I the case of my 100MP captures, it's 2GB per file. I currently have around 200 psb files. In order to use this feature, I have to add about 400G to my storage capacity. Not a huge amount, but significant. Worse, I have to go back and resave every file with max comp. I'd much prefer if there was a way to read existing files - wihout being able to develop them

Using PSD files in LR has the same drawbacks, unfortunately.

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.

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.

Yeah that viewing distance rule is because of shortcomings in res. My 96” wide prints are at 1200dpi and customers view them at 1-2 feet because they /can/. It’s not upscale - it’s massive telephoto stitches.

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).
