My camera has dual SD cards. I have it set so that card 2 is a backup of card 1; ie when I take a shot, a raw file is saved on both cards.
When I import into Lightroom it sees both cards as one source and, unless I manually uncheck each alternate file, Lightroom will import two copes of each file. I have do not import duplicates checked but this seems to only apply to images already on my hard drive.
Is it possible to get Lightroom to either allow me to import from only one of the two cards or not import the duplicate in some other way? I could take the cards out and use a card reader but would rather not.
