P: Increase Supported File Dimensions

Please allow LR to at least 'track' large PSB/TIFF files so that they can be previewed within Lightroom. I do large panos, and run up against this limitation a lot. I don't mind going to PS to edit them, but I'd at least like to be able to see them in Grid view, be able to zoom into them, and just as importantly be able to export them from LR (as smaller files for web, etc.), as otherwise I need to create a smaller (duplicate) file that LR can read to be able to visually keep track of them, which creates confusion regarding whether a given file is the original file or not. It's also odd that some PSB and larger TIFF files can be read by LR, and some cannot; I have not been able to figure out why this is.

Make limitations same as PS ; doing anything else seems arbitrary, especially the 'long dimension' limitation.

Stitched panoramas are getting quite popular, and I'd think that this will become mroe important to fix as time goes on.

"But I would take an interim compromise for PSBs larger than 500MP: allow us to import them into LRC but not Develop/Edit them. At the minimum, being able to store the big PSBs in my LRC database to print and edit in PS would be very, very helpful. Right now I have to save a flattened version down-sized with notes in the filename that tell me where the original giant PSB is."

You might consider the Any File plugin, which will automate this process for you, letting you more easily manage these PSBs within the LR catalog while editing in PS.

Adobe defintiely needs to increase the 500MP limit. Anyone shooting medium format digital and stitching will quickly run into that limit. LRC should handle the same size files PS does.

Yeah, too sad. 

"Is it possible for Lightroom to fully take adavantage of Gigapixel panoramas, psb format, when???"

Unfortunately, Adobe almost never indicates if or when they'll implement a new feature.

Hi, so another couple of months gone by and still not arrived into the 21st century concerning size limits? 

Is it possible for Lightroom to fully take adavantage of Gigapixel panoramas, psb format, when???

You should definitely report those issues as bugs, possibly providing file samples.

If we use a singleshot/pixelshift convention, many camerass today are 50/150, 100/400, and 150/450 (lots of these in development). The FujiGFX100s is 100/400 and at $6000 is become increadibly popular. I've been using the GFX100 (more expensive varient) for several years and was involved when the Pixel Shift beta when that technology was first coming online. At the time my first thought was "good grief, that's a ridiculous amout of resolution I'm not sure I want" but once you use it, you want it. It's like switching to an 8x10 camera with fine grain film. There's so much more true photographic information and it's such a joy to zoom in and look around, and it's hard to decribe how this actually matters and translates into better prints even at realively small sizes like 11x14s. I'm using the GFX100 almost exclusively in an Art Documentation context working with museums and private collectors and the results are truely impressive and lift a lot of eyebrows. And when there's a long and skinny artwork that must be documentated in sections, we wind up with gigapixel images really quickly - and all the problems that go along with large files.

And that's my point. With an all-Adobe LR/PS workflow, working with combined images from modern ~400 megapixel cameras really has a lot of challenges I think Adobe could help us with.  These files don't work well in LR and many features fail or crash - like Photo Merge. "Unable to Merge the Photos. Please try a different projection option" LR says.  The same problems crop us when you use "Enhace Details" from ~100 megapixel fiels. Photoshop performs Photo Merge on these same files just fine but once we have a giant file our only option for saving it as a PSB (Large Document Format) that we can't take back into Lightroom. I'm always saving low res proxy files just to have as a reference in LR which is a pain. Our beloved Lightroom is crippled in so many ways. It can't even import downresed JPEGs saved in Photoshop near the pixel count limits. 

There are a number of other existing and proposed file formats for gigapixel imaging but Photoshop and Lightroom don't support any of them yet. Other apps and websites are supporting formats like SVS, NDPI, SCN, VMIC, ZIF, ISYNTAX MRXS, SZI.   Easyzoom.com is a website that allows us to view super high res files online quickly but getting our Photoshop files saved into a format for this website is a road block.  I'm sure Adobe will make a smart decision about what to support and possibily even propose a new open format that offers greater flexability for gigapixel imaging. I can't wait. Adobe, help us manage this transition into the age of gigapixel imaging!

I agree LrC should support larger sizes.  I was just wondering what cameras did single shot this size.  400 megapixel is a LOT of overkill for my needs or wants.

There is no excuse for Lightroom Classic to cripple the full PSB support found in Photoshop. None IMHO.
