If you compare pictures on a server volume, the pictures are removed and no longer available, unless the server supports a server trash folder. So you can get them back directly from the trash. How can I restore pictures that were deleted by accident?ĭeleted pictures are usually moved to the trash folder. First open the desired photo library, then use the button “Use as System Photo Library”. You need to set the “System Photo Library” in the preferences of the Photos App.

I do have multiple photo libraries – how can I select the one for comparison? On macOS 11 or higher, an AI based comparison can be used that works even better. That’s why false positive results cannot be avoided. Only some parts of the pictures are analyzed, for performance reasons. PixCompare uses color and contrast features to look for similarities.

Photos App support requires macOS 10.15 or higher. Any values below than 70% is probably already pretty different. Any score above 80% indicates a high probability that the pictures are also very similar. When pictures are identical, the score is 100%. When PixCompare compares two pictures, a difference score value is calculated, based on various aspects of the picture. Depending on your specific pictures, you can try to improve the results by tweaking some of the settings. These false-positives cannot be avoided due to the nature of a fast search. However, some pictures are recognized as similar, even though they’re not.
