I connected my camera (Canon T5i) today and Lightroom did not see any photos, although other import utilities do see the photos. after a few reboots and other checks I notices lightroom is not see any photos in the import preview panel. For instance if I select any drive and navigate to a folder with photos in it.
I installed LR a few weeks ago and have had no problems until now.
My next step is to reinstall lightroom. But obviously I would like an easier solution.
After more fiddling around I clicked on the arrow to open the "destination" panel and miraculously the source files showed up.
I haven't had to do this before and based on watching several training videos, I shouldn't have to do anything with the destination to see the source. But, I'm back in business.
