Hello, new user to LR and have a problem with one pic i imported. After import, and when I'm starting to do some post prod work, the picture shows up with a multicolored box that covers up about 40% of the picture on the bottom right. I think I might have hit a key accidentally when i opened the raw file and it came up but I don't know how to get rid of it. I opened the same raw file in PS with no issues. Can someone help? Thanks
This is always a hardware issue ... some piece of hardware has malfunctioned, causing the file to be corrupted. There are many threads on this. You need to try using different hardware to transfer the photo to Lightroom (different card reader or USB cable/USB port, different hard disk) and see if you can isolate the culprit.
Ok sounds good - thanks so much.
I've been having USB 3.0 issues so that might be it right there.
