I have been exporting 1 file at time each after developing a photo, for days from a large cataloge with no probelms, until recently. When exporting 1 pic..LR exports all recent imports from this same cataloge...In this case instead of 1 picutre file it exported 35 a time!...One hint of a problem may be?? the hero photo image is "grey" in the thumbnail..Corrupt or did I do something? After testing a new import things worked. Somehow does this 1 file tigger a mass export? I had to find all the duplicates and unwanted exports to delete...Killing my schedule...
Please share a screen capture of your Export window. At the top, it will say how many images are set to export prior to hitting the export button to confirm something is not an issue.
I believe what Joseph was requesting a screen shot of the "export dialog box" not what you provided.
A 'must watch' video about selecting multiple images in Lr-Classic:
Good video, but does not address my odd issue with multiple exports when only one image is selected. When scrolling through the thumbnails of my collection, only image remains "grey" even when exiting and re-opening LR Classic. Perhaps I hit some unknown keyboard shortcut or ? In anycase this multi-image export happens everytime I try to export this one image.
Thank you again,
SHOW US a screen capture of the export dialog box.
