Imported photos come up as missing On LR4
I imported images from an SD card but the import was almost instantaneous. I normally use 'Copy as DNG' which takes a few minutes and so wonder if the 'add' was highlighted in error, as the images only seem to be on Lightroom if my SD card stays in its reader. They do not show in the 'Previous import' figures or in folders underneath my last successful import. When I tried to import them again, the images came up as greyed out and the import failed. This second time, I had the dialogue set to 'copy as DNG'. It says they are already imported !
I get the missing photos symbols on all these images if I remove the SD card - but cannot find them on my computer, after trying the process to locate them.
How can I reverse whatever I've done ? - so that I can import them correctly into folders in my library, as I can't leave the SD card plugged in all the time - I need to use it for new images.
I would appreciate your help please
