I have a wedding of 800 images edited and ready for export and another 800 virtual copies converted to black and white. All virtual copies are tagged red.
When i came to export the copies, I clicked on Attribute and clicked the red tag. Lightroom tells me there is only 738 selected out of 1600! Er why?
Wheres the rest of my photos? Give them back!
The are probably hidden in a collapsed stack. Select all photos and execute Photos>Stacking>Expand All Stacks. Then reselect your Red-tagged photos and export.
