I've noticed that if I use Lightroom to import photos from my iPhone, it fails to recognize that it has already imported them. I don't see this behaviour when imporing from my Canon. How do I get LR to recognize what it's already imported?
I keep all the previously imported photos in the catalog.
As a quick test, I did an import from the iPhone. It imported everything. I took one additional photo on the iPhone, imported again, and even with "New" selected, it wants to import everything.
I did the same test on someone else's LR and it worked differently - it recognized that it had previously imported all but the last photo, and "New" selected only the photo that really was new.
The difference seems to be the LR version. I have 4.3, the working one was 4.1.
If you copy the photos locally to your hard-drive and then import them, does it work any different? If you make a new catalog does it still work the same? Are your photos on an externally-attached drive running on USB like the iPhone is? Does it work differently if you have LR popup upon memory card insertion vs not?
Presumably these are JPGs, right?
Sorry it's taken me so long to reply. The holidays got in the way of trying these tests.
D'oh! Not that dumb of a question. I had it unchecked. It seems to be working properly now that I've checked it. I must have inadvertently unchecked it around the time I upgraded. Weird. Thanks for your patience.
