Thanks Jim I solved this in the end by choosing to start Sync from the Cloud icon in the top right of LRC in my master catalog, and was presented with a file name of the 'last-syncd' catalog, which I had been looking for of course. Once i loaded that into LRC, everything came rushing back from the past!! Sorted! ... View more

If you can I'd be moving this to InDesign for a more controllable work flow. ... View more

Can I ask if you have been to Adobe Support regarding this issue? ... View more

I do similar and use Transmit (Mac) for this and a few other sync processes. Very reliable. ... View more

There's a similar solution here which should fit with the issue you are having I believe. Another feather to JimHess I believe. ... View more

Thanks for posting you screen shot of your version details. It sounds like from your careful posting that you are wanting to use the same Catalog in two locations, and use Sync function, like I have attached below. . Can you post a screenshot of your expanded Folder structure from within the Library Module? BTW please use the "Insert Photos" icon in the post-reply window for easier forum viewing if you do so.   ... View more

Thanks for the extensive and detailed post, and I am sure this is frustrating for you. I had a look at your linked screen shot (BTW in future its easier for all to use the "Insert photos" icon if your could thanks) and am looking at you file naming structure for each thumbnail. Can you give us some detail about those (I cant see an import template applied) and perhaps camera model? You have probably tested copying to the desktop before the import, but could you confirm this for us? ... View more

Yep: Grid Mode activated by keystroke G (caps only shown here for readability purposes.) Maybe check your Zoom factor (functional for a single image in Develop panel -- keystroke D, and Loupe Mode -- keystroke E) and can be seen in the Navigator window on the left of those modes. ... View more

Hi there: I believe from your description that you are creating two separate books? Is that correct? A little is lost in the translating engine here in your post I think. Can you post a screen shot illustrating this and your LRC and OS version names/numbers? ... View more

Can you post a screen shot here? If that's possible, please use the "Insert Photos" icon in the post reply window and not the "insert/edit link" icon. ... View more

This is very frustrating for you considering you have taken steps to have good hardware. Like you Thomas (I hope that is correct), I have had similar issues with corrupt files and I have ended up lamenting the introduction of "lossless" production software and techniques over the years. I found that as that emerged on digital platforms, I dropped the ball somewhat on rock-solid backup strategies for myself. Somewhat recently I have taken back ownership of that aspect of my work and it is front and centre when I use any editing platform. I know this is of no help to you and I sympathise with your issue, as you are most likely a considered and experienced user of Lightroom Classic. I presume you are working in LRC with latest update installed? ... View more

Unfortunately this looks like you might be little stuck with is issue, Charlie. Can you post back as to where you stand so we might be able to close this thread if there are no further input with a solution for you? ... View more

Hi Daniel It will help us if you can have a look at the two links thanks.

I had a careful read through this thread and while I see Michael had the initial correct answer for the issue, I felt that johnrellis had one more step which may have better work-flow implications if followed. Maybe Zachary5C62 could post back with a perspective on this for the forum? I just don't want to miss giving respect to the original correct reply where possible but at the same time looking for comprehensive solutions that will benefit all end users. ... View more

Reading the information posted in the link by johnrellis, I'd agree with the sentiments in that set of posts on Lightroom Queen that your 8mm lens is the issue. Can you post back that you (maybe reluctantly) concur with those opinions / facts so we can mark this post solved? ... View more

You could try going back to LRC v10.0, but that may have Catalog implications. But if that works, that would at least get you to the point where you could successfully reimport? Would that be useful? ... View more

Thanks for posting your issue and yes its probably frustrating for you. But Can you post your LRC and OS versions thanks? Obviously you are posting drone shots. Is your drone software capable of setting  "aperture priority mode" for the panorama set? I have found this to be essential for better stitching of panoramas. Posting a screenshot of your Develop module in action on one of these images would be useful. When you do, please use the "Insert Photos" icon in the post reply window and NOT the "Insert/edit link" icon.   ... View more

Please post your LRC and OS version numbers. BTW, thanks for attaching your issue correctly with using the "Insert Photos" icon! Is this a sudden change to your Library module? ie: has it happened before? Are you images available to see in any other Module? Can you provide a little detail of your storage strategy? ...

Can you please describe in more detail your editing workflow? Many things can go on in the Develop module and a good description can help other users here see what you are doing. Can you also post a screen shot of the "files not found" problem? Are you seeing the exclamation mark (icon) in the top right-hand corner of the image thumbnail which is missing?   If you post a replyand attach a file here, please use the "Insert Photo" icon, and NOT the "Insert/Edit link" icon in the post reply window? ...

A couple of good links from WobertC to follow. I'd agree with him that YOU have more control over your images, and are not reliant on Adobe (or other) cloud solutions necessarily. I'm using a lossless NAS file system as well as another well-known cloud storage platform for storage. No sync issues ever. No drain on a smaller internal hard drive for space. Everyone will have moved to the cloud in 10 years I'd say though. (or Mars) ... View more
