I created a second catalog in lightroom 4 and imported a number of photos. the photo id number i.e. the name of the photo was not imported so the second catalog has an entirely new set of identification numbers. this is not helpful to me as I have references/notes to the original numbers. how do I indicate that I want the original names/numbers to transfer to the second catalog? can I fix what has already happened?
Also: now that I have the second catalog, I want to delete some photos with out deleting the photo from the original catalog. so far, when I delete a photo it gets deleted from both catalogues in lightroom.
