Photos import then go black until I apply Auto tune in the Develop Module. This is new behavior to 6.2.1. It did not even happen in 6.2. How can I get them to appear without this step?
There is a bug in 6.2 and 6.2.1 when you have "apply auto tone" set in your preferences->presets. It will Apply a -5 exposure adjustment upon importing. Turn off auto tone or roll back to LR 6.1 for now.
