Aperture is reseting all my curves! HELP!

I have never seen this happen before. It looks like Aperture were reprocessing your images for an upgraded raw processing.

What is your Aperture version and your Mac OS X version?

How did you apply the Curves-adjustments? Are they part of a plug-in package with predefined adjustments, that you installed as an add-on? Or did you define your own Curves-presets?

Have you upgraded Aperture recently? Installed any plug-ins? Moved your Aperture Library? Did you have any crashes or needed to force-quit?

Do you shoot raw or in another image format? Where is your library located? Is it referenced or managed?

And do you have a backup or vault, where you could restore your library from? If not, I'd recommend to make a backup asap, before you touch, edit, and currupt any more image versions.

I've had this exact thing happen to me (https://discussions.apple.com/thread/4772531). The bad news is that I don't have any "fix" for you. I restored my library from a backup but now I will always be afraid to rebuild my library in any future troubleshooting efforts.

I don't recall if an initial rebuild triggered the problem. I just remember opening Aperture one day and watching it change photo after photo that I'd select in the viewer. I don't remember what I was working on or if I was troubleshooting something else. But I can say that I proved to myself that a rebuild will repeat the problem; I just can't confirm if it was an initial cause.

I used Time Machine to recover my library to a pre-curve-disaster state. Once restored you don't have to rebuild the library. The only thing I lost was metadata entry (keywords, location, etc) but my curves weren't screwed up.

The ONLY thing I saw change were the curves adjustment brick. Each of the other adjustments remained the same for the pictures. Metadata remained unchanged as well. Did you happen to read through the past discussion I linked? The article from apertureexpert.com described what the curves changed to. Essentially it replaced my s-curve adjustment with the "old" style curve adjustment. And it happened to any photo I had adjusted in the library, not just a few certain projects, but any and all photos that had a curves adjustment applied. Ouch.

My library is referenced so it was a little less painful for me to restore but it ticked me off nonetheless.

No, knowing won't help fix it as far as I know. I got lucky in that I had a recent Time Machine backup & I didn't lose tons of work. I hope you're able to find an answer because I've looked around the web a bunch & couldn't find any relief.

Here's the article:

My bug was like I option-clicked the auto button in the curves brick, as he described.
