Can anyone help with this problem because I'm really stumped!
I'm using Lightroom 5.7 on a Windows 7 laptop & not had any problems up until now but images in Develop mode show large red areas as though they are over exposed (see screen shot). The same photos have previously been fine up until now & are fine in Library mode & if viewed in any other programme. I have tried uninstalling & reinstall but this has made no difference. Any advice would be helpful, thanks.
This is a highlight clipping indicator. Press J once or twice or thrice to make it go away.
Look in the top right corner of the histogram, there is a highlighted triangle which means you have selected the highlights indicator, the red areas are blown highlights. Click will turn off.
Thanks, I don't think I would ever have found this!
