Lightroom: 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.

This reply was created from a merged topic originally titled Lightroom: What is the largest file Lightroom 3 can handle?.

I have a client whose studio I set up with Lightroom 3 who regularly deals with very high-resolution drum scans of 8X10" film. She has tens of thousands of scans and other files that need to be organized, and I was hoping that I could use LR3 to do it. However, when I attempt to import the scans into LR3, I repeatedly get a message that tells me that some of the files are "too big." The error dialog allows me to locate the problem files, and they are always TIFF scans form 8X10" film done with and Aztek.

I called Adobe tech support about this, and was told that there is a 65K X 65K pixel dimension limit in LR3 and PS CS5. All of the files in question are below that limit. When I mentioned this to the tech support rep, he became confused. After muttering about 2GB file size limit for a while, he told me that I should use "professional software" such as Bridge. I asked him directly if there is a 2 GB file size limit, and he said there is not.

Since that time I have done a great deal of research online and in various textbooks, and there seems to be some disagreement about the maximum file size limit in terms of actual, practical applications. I would be very interested to hear from those in this forum on this topic.

This reply was created from a merged topic originally titled Size Limitations for Panorama in Lightroom CC - Feature Request.

Feature request: This note is to encourage Adobe to expand the size limitations of panoramas in Lightroom CC. I understand that this limit is a maximum long dimension of 65,000 pixels or a maximum pixel count of 512 megapixels. Such a limit makes it impossible to obtain wide angle panoramas with long focal length lenses to obtain extremely high resolution. For example, a 100 mm lens on a 24mm x 36mm sensor turned to vertical orientation (24mm wide) requires approximately (ideally) 26 frames to make a 360 degree panorama. If a 50 megapixel camera is used (e.g. Canon 5DS), this image will be approximately 150,000 pixels wide or almost three times the present limit. It will also have approximately 1300 megapixels, again roughly three times the present limit. This means that a Canon 5DS cannot be used to make even a 180 degree panorama using a 100mm lens in the vertical orientation. Another use for panorama is very high resolution art reproduction using panorama to merge a mosaic of separate images of one artwork. The size limit constrains what can be done to a significant degree. Panorama creation in Lightroom CC is fantastic because it is easy and results in a RAW image. But the present size limit is a real constraint! My recommendation would be to quadruple the linear dimension and make the pixel limit ~10 times as great. One additional point: When too many pictures to merge are selected, Lightroom should return a statement "Panorama is too large - limit is a maximum long dimension of 65,000 pixels or a maximum pixel count of 512 megapixels" instead of some thing like "Panorama failed - try a different projection". This would save many people a lot of time. It took me several hours of experimentation and finally a Google query to figure out what the problem/limitation was. Thank you for your attention.

This reply was created from a merged topic originally titled Files are Too Big error importing to Lightroom.

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

This reply was created from a merged topic originally titled 2018 Lightroom Panorama file limits?.

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.

This reply was created from a merged topic originally titled Giga Pixel Panos.

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.

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

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.

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

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.
