Lightroom Classic v10.2: Sync from previous photo crops the image

Hi everyone,

I've just noticed odd behaviour after recent LR update on my Win10 64bit - I'm processing photos from 1 photoshoot, using nikon d700 and 50mm lens for all of them.

As conditions are the same, my workflow is to apply settings to first photo and then sync across rest of them so if I'm selecting multiple images and then sync settings either from Library or Develop module - that's great, working fine and as expected.

However, sometimes I'm doing manual tweaks and then I want to apply those settings to the next photo so what I'm doing is: in Develop mode, go to the next image and hit "Previous" button next to "Reset" - when this is used the image is getting marginally cropped (probably by 1pixel) even when previous image wasn't cropped at all.

This change is only marginal but alters the aspect ratio without user's knowledge and only indication is a small crop icon in the filmstrip thumbnail.

Thank you
Marcin

Greetings,

Updates to Camera Raw, Lightroom Classic and the Lightroom Ecosystem products for Desktop, Mobile and Web, were released today and contain a fix for this issue.

Please refresh your Creative Cloud application and install your update when it becomes available. Thank you for your patience.

I know this because I'll export about 20-30 files to Zerene Stacker and it won't stack them because the first file (every time I export a series of files for a focus stack) is always 2 pixels larger and I get an error message that says the image file is a different size.  Looks like a NEW bug in Lr.  This has never happened to me before.  I'm using the most current version of Lr Classic.

Sorry.  Typo.  The first image exported is always 2 pixels larger.  So for my D850 the first image exported from Lr is 8256x5504. All other files in the same export operation are 8254x5504 pixels.

Bruce I just tried it with my images from a Nikon D850 and all 17 were 8256 x 5504 and Zerene Stacker had no problems  LR 10.2 Mac OS X 10.14.6

Wow.  So why is my Lr exporting on larger image and the rest the same size.  Frustrating!  So mine is exporting the first image the correct size and all the others 2 pixels shorter on the long side.

seems that way.  You can check the image dimensions in the metadata panel and see if they all start the same

Good idea.  Just checked that.  If I export the images without cropping all is fine.  If I crop the first one in the series then sync settings (incl crop) for the rest, the first image is different from all the others.  I thought syncing was supposed to make them all the same!  So the problem is not with export, it's with cropping and then syncing all the files in the series in the hope of making them all the same.  Hummmmmm.  Still odd.  Why is it doing that.  Seems to be a new thing for me.  I never had that problem before.  Just started about a week ago (just after I updated Lr to the newest version - I don't know if that has anything to do with it).

I am seeing the same thing!!!!!!!!!!!!!   It shouldn't be doing this.  Another unintended consequence is when you take a series of images into a focus stacking program like Zerene Stacker the program will not stack the series because the first image is a different size (just one or two pixels) than the rest of the images in the series.  It looks like a bug to me.

Can somebody write me out a step by step method to reliably reproduce the problem so that I can test it? My first attempt did not reproduce the issue.

Hi there, not sure what happened to my post but I did upload a screengrab from the LR: https://youtu.be/a7Lj_JE9lMs

the 0:19-0:29 are syncing without crop checkbox ticked and then next attempt is with the crop ticked.

At the end, there's an untouched pair of photos that shows the issue.

See my post above. I cannot tell what is going on in the video. I need step by step instructions.

  1. Using PC, current ver. Lr and Nikon D850
  2.  Shot a sequence of pictures using D850 focus shift feature for stacking
  3. Download into Lr
  4. First picture in sequence is 8256x5504 pixels (same with all the others)
  5. I make exposure adjustment to the first image.
  6. I use "Synchronize Settings" to copy that adjustment to all the other pics.
  7. I look at the EXIF data and the first image (source for adjustments) is 8256x5504 pixels for Dimensions and Cropped values.
  8. All the other images are Cropped value of 8254x5504.  Two pixels shorter on the long side.
  9. Having the source image with different dimensions than the rest of the images causes a problem with a program like Zerene Stacker.
  10. Zerene will only stack a series of images if they are all EXACTLY the same size.
  11. It happens like this even when you make adjustments other than size.  When I crop and Sync Settings the same thing happens.  The first image is always one or two pixels larger in one dimension.
  12. I hope this helps.

If you use the [ I ] key to turn on Info does Lightroom report the pixel dimensions the same as EXIF or different?


Using these instructions,  I was not able to reproduce the issue

Yes, using the "I" key shows the same dimensions as the EXIF data.  I shot and ran more focus stacks this morning and I'm seeing the same anomoly.

With your test files, I am not able to reproduce the behavior. After sync the images remain identically sized. 

A screenshot of your Sync dialog might be helpful.

Have you reset your preferences?

I reset preferences at start-up (Opt + Shft).  I cropped one image and then copied the settings to others in the focus stack and everything appeared correctly.  I thought that solved it.  However, I reset all files and tried it again and the first image was different by one pixel compared to all the images the settings were copied to.  I repeated this 4 times and the problem still persists.  The Synchronized Settings dialog box has all boxes checked except Upright mode and Process version were grayed out.

A screenshot of that dialog would be nice if you could provide one.

Ok, your previous post to the screenshot says you cropped: 

Your instructions earlier said:

  1. First picture in sequence is 8256x5504 pixels (same with all the others)
  2. I make exposure adjustment to the first image.
  3. I use "Synchronize Settings" to copy that adjustment to all the other pics.

Using your earlier instructions can you replicate (without the crop)?

New test:

  1. First picture measures 5504x8256 pixels
  2. Made exposure and vibrance adjustments to first image.
  3. Shift clicked last image in sequence.
  4. Synced first image settings to all others.
  5. Checked all image size measurements.
  6. First image 5504x8256.  All synced images measure 5504x8254.
  7. Reset all images and then ran this test again.  Same results.  The first image dimensions are unchanged.  All others 2 pixels smaller on the long side.

I tried again using your files and this recipe and I still cannot reproduce this. All files end up 8256x5504.

So the question is, what could be different from my computer or my Lr that would cause this?  And, is anyone else seeing this anomaly?

I've tried it on Mac (10.15.7) and Windows 10 and both systems behave correctly.
