Now that LR 9.2 supports importing PSB files, it would be a little more convenient if you could specify PSB as the default format for editing in Photoshop (Preferences > External Editing > Edit In Adobe Photoshop > File Format). 

As it stands now, if you want to save an edited file in PSB format, you must remember to do File > Save As and select Large Document Format.

Very much agree with this!  When I saw the release notes that PSB files are supported I was shocked to see that it isn't an option to use that format for external editing in Photoshop.

Or ask Adobe to remove any need for PSB?

It may well support PSB but you try importing them a modest 4.5 gb comes back with a too big error message

Lightroom Support for PSB is currently limited to files whose long edge does not exceed 65K pixels or the entire image is less than 512 Megapixels and it must be saved in Max Compatibility. Photoshop is capable of exceeding these values.

It's sufficient for the vast majority of the small minority who are forced to save as PSB.

I don't think Adobe needs to spend valuable development time to support files greater than 65K pixels or 512MP in Lightroom.   I am sure the percent of people that need this is very close to zero.

There are two general use-cases for needing to use PSBs:

- Starting with a high-resolution image, well under LR's pixel limits, and adding many layers in Photoshop to implement a non-destructive workflow. 

- Starting with a ultra-high-resolution image exceeding LR's pixel limits, produced by a panorama merge or a specialized (very expensive) camera.

I believe that the great majority of LR users of PSBs fall into the first camp.  My belief is based on monitoring this forum and the community forum for a decade and on feedback from customers of my PSB Quick Look plugin for Mac OS.

A typical example of the first use case: The retouchers in an ad agency start with a full-frame DSLR photo of a running shoe and, responding to requests from their art director, end up with more than two dozen layers.

I think you're right about the two groups, but very few people ever set out to create PSBs - they do so only when they can no longer save their work normally. If you need PSB, you just choose it in Photoshop's save dialog and wouldn't need or anticipate making such a choice in LR.

I disagree.  With ultra high resolution cameras like the GFX 100 and the desire to composite 16 bit images in Photoshop I routinely run into the 4GB file limit of TIFF files. A side benefit is uncompressed PSBs, although can get huge actually save to disk much faster than compressed TIFFs so they always would be my preferred choice.

The "side benefit" being that compression takes longer than saving uncompressed?

Hi John, I think you misread. The side benefit is the uncompressed PSBs save much faster than compressed TIFFs on any large file sizes, not just ones approaching 4GB.

You need to compare uncompressed PSB against uncompressed TIF, Matt. I doubt you'll see any difference.

I think the point being made is that you cannot use tiff above 4gb so you either need to compress the file of save as psb and the psb saves and opens quicker than a compressed tiff
