My dilemma is about editing a photo in the Develop mode in Lightroom 4. Why does the library now show two photos with the same file number, the original and the edited photo. The edited photo, with the same number, has the question mark above it. Sometimes I can find it in the process recommended. Sometimes the finder answer is You may not have two files with the same name. Help!
Did you edit the photo in Photoshop? Lightroom is a non-destructive darkroom and cataloging program, so if you edit a file destructively, it will save the edited version back in to the catalog while keeping a copy of the original file as well. This may be what happened.
This is functioning as designed and I am not sure what you are indicating is a problem that you are experiencing. It should be safe to remove either one from the catalog. There should also be an option to edit an image destructively without adding the result to the catalog, but I don't have Lightroom on my local machine to give more detailed instructions.
