P: Increase Supported File Dimensions

Replying to Robert Somrak who merged my thread... seems this request has been around for a while.

Nowadays, with a 60megapixel camera you can hit that limit in 18 images, and that’s just 2 rows of 9. Understand it’s not a majority issue but won’t be as rare as near zero and might be an easy tweak that will make the lives of some heavy users much easier.

I suspect many are just using PTGui and tolerating that it doesn’t output DNG.

The ability to merge panorama's using Camera Raw from Lightroom or Photoshop and output a DNG file is FANTASTIC!! It's something I've used and appreciated since it was launched, and particularly the continued controls for white balance that this allows after the panorama merge.

Now, with the proliferation of high resolution cameras, the recent performance improvements across the stack make the workflow SO MUCH easier to live with, but with those cameras it's also now pretty easy to go over the 65,000 pixel / 512 megapixel limits in Camera Raw, which impact Lightroom and Photoshop in the same way if you want to output a DNG. The automation will let you go over this in Photoshop, but only with PSBs or TIFFs as the output.

Is it time to try and increase these limits Adobe? I for one would be hugely appreciative and I'm sure I'm not the only one!

My point was that PTGui seems to hit its limit much sooner than that, and other programs may do so as well, when it comes to JPG specifically - creating the output in the first place, not getting it into LR.

I suppose the authoring app probably gulps a lot of resources computing the JPG compression and encoding a high MP image, which the far simpler TIFF creation would not consume.. even if the MP may be the same, and despite the larger saved file size of the TIFF.

LR imposes the same limits on all formats: 65,000 pixels on a side and 512 megapixels total:

One comment: there are pixel dimension limits when creating a JPG as pano output, e.g. in PTGui, which may not apply to TIFF.

A TIFF that's e.g. 8-bit and compressed, is not necessarily completely unmanageable.

I agree. As a partial workaround, the Any File plugin will let you catalog (but not edit) very large photos.

It would be a nice feature if I could catalogue and manipulate also Giga Pixel photos. I have all my different single photos for a Giga Pixel pano in LR, exporting all of them and creating the pano in PTGui. Unfortunately I can't import the pano back to LR because it's exceding the max supported amount of pixels.

Here here!!

Can we please get a boost to the file size limits for the Panorama tool in Lightroom CC? As far as I can tell it's been stuck at 65,000 pixels or a maximum pixel count of 512 megapixels since this function came out. 

Most modern computers can handle bigger files and it's messing with my workflow to have to leave the Adobe ecosystem to come back in. 

I ran smack into a problem importing a panorama file that is 46902x13200 pixels and 300DPI 39.3 MB in size and dimensions are 44" x 156.34" that I had just edited in Photoshop CC..  There should not be a limitation for files this size for the product. Especially if it can be opened in Photoshop. Using the latest builds/versions as of 7/1/2018
