- From where are you importing images, i mean the source of the images
- By the way try this, open LR
- Now open preferences of LR - presets and uncheck apply auto tone adjustments
- Restart LR and then try importing images again.
your solution works. many thanks
but why do you think this is, I have been using the preset in question without problem in the past?
Not particularly sure but this issue has appeared with new Mac OS X El Captain and LR 6.2, i believe it has something to do with the graphics of the new mac OS X, and we indeed are able to reproduce it our ends too.
Need hotfix ASAP. This is NOT GOOD.
There are many confirmed issues with LR 6.2 - you may try the steps here: Update on Lightroom 2015.2 / Lightroom 6.2 Release
Anyhow, you are best helped if you roll back to 6.1.1 as many users: http://www.lightroomqueen.com/how-do-i-roll-back-to-lightroom-2015-1-1-or-lightroom-6-1-1/
