P: Increase Supported File Dimensions

I would appreciate if LR would support images with 65k x 65k pixels (i.e. drop the overall 512M-pixel limit). I have several stiched images, that I can not handle with Lightroom, and I do not want to use two different Applications to manage my images.

P.S. and please make the limit 2^16 x 2^16 and not 65000x 56000.

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

      The Hasselblad H6D-400c produces 400 MP images (about $50K).  

       

      I think a somewhat more common use-case is a high-megapixel panorama generated from 50 - 100 MP input images.

        Which cameras are exceeding 400 megapixels per shot.

        As cameras are exceeding 400 megapixels per shot now I think it's time for Lightroom to start lifting limits accordingly. Lightroom's Photo Merge crashes on large files where Photoshop does not. Photo Merge limits appear to be much lower than Photoshop's so lifting these limits would really help and allow us to do more in Lightroom and less in Photoshop. Lightroom's 512 megapixel JPEG file size limit is particualrly frustrating to me and one that I'd love to see increased. Thank you!

          I agree with this. I normally do my panos in Lightroom. Sometimes, I do them in Photoshop. If Photoshop can do the stitching, then why can't Lightroom import it back ?

          Got it. You are right.

          "So, I am not sure of the point you are trying to make, sorry."

           

          I was responding to your last sentence:

           

          "It looks like a previous member reported a 512MP limit, but I think it is a 512MB limit. Please correct me, if wrong."

           

          Thus I corrected you -- it's 512 megapixels (MP) not 512 megabytes (MB).

          Sorry, I am missing something. First, I was wrong, the jpg did not import. I had created a "small" version that did get imported, but it was not the same resolution.

          You are restating the limitation that the OP originally requested to be changed, which I agree with. I understand the limitation, that is why I said that I agree with others in this thread that it be increased. So, I am not sure of the point you are trying to make, sorry.

          The good news is that it does open in Photoshop. The bad news is that it does not even create a placeholder in the LRC catalog so that I can remember it is on my disk (one of the reasons I use LRC to catalog all my photos). I'll rename the low resolution version something like "low_res_version full res is in same file folder-open it in PS.jpg".

          "It is a tif file, 55765 x 15769"

           

          That's a total of 55,765 * 15,769 = 879,358,285 pixels, or 879 megapixels.  LR's maximum size is 512 MP, with no more than 65,000 pixels per side. See the very bottom of this help article:

          FYI, it is a pano of the complete view of the Milky Way, if interested 🙂
