I'm using Lightroom 6 -stand alone--and the program will not load my current photographs. I only shoot in raw and wonder if that has something to do with it blacking out my photographs?
This issue occurs when Auto Tone has been applied to your images.
For existing photos, select all your images in Grid view, and then click the Reset All button in the Quick Develop panel. Then, click the Auto Tone button to properly apply this feature.
To prevent this issue from occurring in the future, choose Lightroom > Preferences > Presets (Mac OS) or Edit > Preferences > Presets (Windows). Reselect Apply auto tone adjustments.
