I am working with a huge photo library and from time to time I experiment quick editing on some pictures. Sometimes I also make uncontrolled changes which apply on a set of pictures I can't correctly see.
In these situations I would like to be able to exit
iPhoto without saving these unwanted modifications.
I didn't find any preference permetting to achieve this wanted behaviour. Hopefully I have this basic function on most applications which can modify files or libraries beyond what the user can see.
Is there any hidden
iPhoto which would give access to such a simple function?
I am actually running
iPhoto '11, but I'm interested by this function for any version running on Lion, Mountain Lion & Mavericks.
