P: Local Adjustment or Synced spot removal to a cropped copy not sampling from the same as in the or

I'm seeing easy-to-reproduce shifts in the clone source when copying from virtual copy to original:

Yes I am aware 🙂

Thank you for your comment.

Just to make sure: are you aware that you can manually move the clone source to get the best possible result? Using multiple VC’s and then syncing the best result to the original sounds rather cumbersome to me compared to just moving the source to where you want it.

The biggest concern for me is that sometimes without involving a crop, synchronizing the spot removals to a copy also leads to some kind of modifications!

Before V10.2 I sometimes did different attempts of spot removal by using virtual copies and then synch the best result to the original. Now I don't trust LR anymore.

This behavior changed from LR 10.1.1 to LR 10.2.  In LR 10.1.1, copying a Spot Removal > Clone to a cropped virtual copy doesn't change the source of the clone, while it does in LR 10.2.

Here's the original and the cropped virtual copy in LR 10.2:

Note that the source has changed considerably.

For comparison, here are the locations of the target and source in the original and the virtual copy in LR 10.1.1 -- they're exactly the same:

Note that in both LR 10.1.1 and 10.2, the source of the clone is not within the crop of the virtual copy.

“Expected - spot removal over the same part of the image and sampling from the same part”

When you sync a spot removal, Lightroom will resample. The reason is that you would normally not sync between two identical images, but for example a sensor spot in a series of similar, but not identical images. Because the images are not identical, the best sample spot may not be the same place for each image. Sampling from the same spot will only take place if you manually moved and replaced the sample point on the first image.

Why don’t you simply create a second virtual copy of the first virtual copy, and then crop that?
