When marking a photo with a Reject Photo or pressing the Delete key, Lightroom only deletes that photo from that collection. But what about the other collections and what about really deleting that photo?

  1. The hard way? Switch to the collection All Photographs, you will keep your position and Lightroom will highlight the photo that you want to delete and press the Delete key.
  2. The easy way? Stay where you are in the collection and press the following key combination, for Windows: Ctrl + Alt + Shift + Backspace or for the Mac: Command + Option + Shift + Delete (I can do it with 2 hands and 4 fingers).

What about the smart collections?

Pressing the delete key means nothing, since the smart collection is created according to your selection criteria. Either the photograph matches the selection criteria or not. But was about deleting a photo, in a smart collection, from the catalog?

  1. The hard way? Switch to the collection All Photographs, you will keep your position and Lightroom will highlight the photo that you want to delete and press the Delete key.
  2. The easy way? Stay where you are in the smart collection and press the following key combination, for Windows: Ctrl + Alt + Shift + Backspace or for the Mac: Command + Option + Shift + Delete.
