iPhoto 9.3.1 - Adjust Controls Messed Up
Has anyone tried editing (adjusting) their photos in iPhoto 9.3.1? I just tried it, and the sliders (e.g. white point, highlights, shadows) are giving really weird results. I'm starting to wonder if it's an incompatability between iPhoto 9.3.1 and the graphics card (ATI Radeon HD 5670 512 MB) in my iMac (21.5-inch, Mid 2010).
Here are two screenshot, showing what I see when I adjust the black and white point sliders. Look how unnatural the photo looks. This definitely wasn't the behaviour of these controls in iPhoto '09.
