LRC Changing graded photos to nasty yellow grade one by one

Just an update here in case anyone else is a stupid as me...🤯

The 'Screw Autosync' plugin that was suggested by John seems to require a manual keystroke for every photo you want to revert. From the plugin text: '...click the 'Screw Auto Sync' button, then wait for a dialogue box - once for each adjustement to "undo."' So even if the plug-in did work, you'd have to manually click for each image to be corrected. So no go there...

I've just tried out the Apple Automator using its 'Watch Me Do' & 'Loop' functions to record and play back an endless loop of me correcting the 'Paste Settings' action and then stepping to the next image in the library. It seems to work pretty well, and has corrected one hundred or so images in a test run.

I'll be leaving it on overnight with the replay speed cranked to x10 to correct the entire catalogue. Then all I'll need to do is find the images that I've already corrected and adjust their individual histories accordingly.

Hopefully, that will be the end of it. Thanks all.

"If I navigate quickly to an image that hasn't been yellowed, it's already got the paste settings in the History panel, and it then goes yellow before my eyes. I guess in LR's catalogue, all the images are yellow, and it's only prompted to update the preview of them as I look at them."

Right. When you paste or sync settings to a large number of photos, it completes quickly, since LR is just copying the settings themselves to the catalog entries for all the target photos. Then in background, it starts regenerating previews for all the changed photos, which can go pretty slowly.  It prioritizes the regeneration for thumbnails that are currently visible on the screen.

While it's certainly possible there's a LR bug that did the Paste Settings, like Per, I don't recall a bug like this ever being reported in the past ten years. So Occam's Razor suggests that it was an accidental Paste Settings on your part. Though the -100 Green Sat setting is indeed wierd.

I agree that it a good course of action is to backup your current catalog, try Screw Autosync, and then if necessary re-upgrade from your previous version (from mid-January).  

When you get this sorted, you should invest some effort into making sure you have at least weekly backups of your LR catalog.

John,

I considered the 'accidental paste' scenario, but I'm not sure it explains why the app would keep applying the Paste Setting after restarts and resetting the preferences. Or does it? Would LR continue to do something like this after being shut down and restarted/reset etc? If I pasted settings accidentally, quit and then LR backed up, would this happen?

Maybe this is it. As a matter of fact, if I navigate quickly to an image that hasn't been yellowed, it's already got the paste settings in the History panel, and it then goes yellow before my eyes. I guess in LR's catalogue, all the images are yellow, and it's only prompted to update the preview of them as I look at them.

I'm now thinking that the 'accidental paste' might be correct. I've pasted to the entire library, quit and accepted a prompted backup. Then, next time I opened it, boom. You think? Or no? I'm still thinking that the -100 Green Sat setting is very weird. Not something I'd ever do when working normally.

If I understand correctly, LR created new version of my catalogue when I updated to the latest version in mid January. So I have a current version and one from back then. 

But maybe my first course of action should be to backup the catalogue and try the The Screw Autosync LR plugin? If it does work with this version of LR, I could just select all photos and go back one step in their histories. Then all I'd need to do would be to find the handfull of photos that I've already corrected by hand (which should now be yellow again) and fix them again.

Thoughts?

Perhaps you accidentally pasted develop settings (keyboard shortcut Ctrl/Cmd + Shift + V) while all the photos were selected?  LR would then rebuild the previews for all the photos one-by-one, in a manner consistent with what your observing, and that would account for Paste Settings in the history panel for each photo.

Whether the Paste Settings was accidentally done by you or by a bug in LR, it appears that it has been applied to every photo. I think it's too late to try an Undo, since you've restarted LR.  Options that come to mind:

1. Revert to the most recent backup of the catalog proper (if you have one).

2. Manually go through each photo and move back one history step. (About 10 hours of clicking :-<)

3. Use a keystroke macro utility like Autohotsync on Windows or something similar on Mac to repeatedly go back one history step in Develop and then advanced to the next photo.

4. If you're technicaly proficient with SQL databases, you could try this SQL script to move back one history step on every photo:

5.  The Screw Autosync LR plugin was written specifically to move back one or more history steps on selected photos (esentially doing what's described in 4). But its author passed away five years ago. The plugin is still available here:

but I don't know if it works with LR 9 or not.

Make sure you make a backup of your catalog before trying anything!

I've never come across anything like this before.

But it seems that settings are being pasted automatically.

Open an image Develop, and compare the positions of all sliders before and after, and make note of the changes.

Then see if you have a preset that contains these settings.

But even if you do, what happens is still a mystery.

And the histogram doesn't seem to be displaying correctly either, there should be some red spikes at the far end for the glove picture. Does the histogram change when you go one step back in History from Paste settings?

In any case, I would try resetting the preferences.

Please post a screenshot of the entire Lightroom window, showing the Library with yellow photos.

Please also post a screenshot of the entire Lightroom window with an image open in Develop, and make sure that the History panel, Histogram and Basic panels are all visible and expanded.
