Why are photos turning all white or black when I edit?
When I try to edit a photo in iPhoto it turns all white or all black.
When I click undo the photo goes back to normal.
Initially I thought it only happened on photos from my iPhone but it is now happening to photos from other camera's.
The issue is not specific to any type of edit I am trying to do, it happens with all methods of editing.
I am using iPhoto 11 version 9.4.2
Can anyone help?
