Aperture 3 preview of raw file greenish
Just recently, perhaps after a Digital Camera Raw update, the previews of raw images Aperture 3.2.3 imports are dark with a distinctly green cast.
This happens when I let Aperture import direct from the camera, a Lumix FZ 150 with either of my two Lexar SDXC cards. During import, the thumbnail previews look normal. But during processing they turn green one by one. (The first time I saw this, I turned green. I thought there was something wrong with my camera or new 600x card.)
Double clicking the thumbnail produces a greenish full-sized image, which then changes to a normal image (I assume as Aperture displays the raw image).
If I drag the same raw files from the Finder, Aperture generates the previews normally.
This problem is easy to solve: select the greenish images, hold down option and choose Photos > Generate Previews. This forces Aperture to rebuild the preview.
(I found a few older discussions with similar-sounding problems, but none exactly the same.)
