P: Support cataloging PSB files

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.

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. 

Merging with existing topic

Please reference the new conversation here: Add PSB for external editing

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

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

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.

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 🙂

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.

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.

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.
