How to lock versions to prevent inadvertent modification?
When I process valuable images in Aperture I like to use versions to capture different stages of the editing process. From such a version I may then derive one or more further variants either for different purposes or for comparison of different processing options. At some point I obtain one or more versions that I consider final. It would be very useful to be able to lock or "freeze" versions (not only the final ones) in that procedure in order to prevent them from being inadvertently modified.
I could not figure out how to do that, does anybody have a solution?
Thanks for any advice.
