I have been using this version of Lightroom without difficulty for one week. Today, I imported some new photos from my camera to Lightroom 5. When I was finished, I planned to edit some other photos I have stored in my catalog from previous dates, however I discovered that every photo in my catalog (about 22,000+) has been automatically darkened without any action on my part. It almost looks like someone lowered the brightness on all of them
Needless to say, I am very concerned about my 22,000+ photos, they were not dark prior to today. How do I get them back to normal?
