Dear all

I have difficulties adjusting colors in my images, I am trying to adjust a specific hue, by selecting a color with the eyedropper (Adjustments-Color). Instead of selecting the desired hue from the picture, it always selects red color, regardless of the color selected in the picture (it actually selects the correct color when pushing the mouse button down, but then selects red when releasing the mouse button). I tried that with different pictures (jpg and raw), allways the same problem. I am using Aperture 3.4.3

Anybody with an idea? Thanks!


Aperture 3, OS X Mountain Lion (10.8.2)

    Do you have a "straighten" adjustment applied? Does this still happen on images that don't have a straighten adjustment?

    No, I didn't use the straighten tools on these pictures at all!

    That's odd, are there any other common adjustments being used on these images that are displaying the issue? Does it happen on images that have no other adjustments applied?

    I took a new picture without any adjustments (jpg and raw) without success. I even reinstalled aperture.. Did anybody try with Aperture 3.4.3?

    I just tried with my older MBA (instead the MBP Retina).. And its working on the MBA, but not on the MBP (with the same photo)! On the MBP, it does also not show the current hue value, when I move the eyedropper over the picture. As I allready wrote, it does take the correct hue value by pressing the mouse, but when releasing it switches to red..

     

    It seems to be a bug, Apple please fix that!

    Do you have any other user accounts on your Retina MacBook? Does the issue still happen in a different user account?

     

    If doesn't happen in the other account, the issue is likely with one of your preference files. There's instructions on how to do that in the middle of this article.

     

    I doubt that the problem is with your library, but you could try switching to a different Aperture library just to rule that out by holding the "Option" key when you launch Aperture.

    Your idea with the preference files helped.. It is now working! Thank you so much!
