I was going through my library, trying out some of the new stuff like Faces. I happened to run across this odd problem among some test shots I took back when I first got my D700. I haven't touched these photos at all in Aperture 3. In my Aperture 2 library both of these images look similar, but Aperture 3 did something weird with the second one (along with several others in this set) when it imported the old library. Note that the second image is a TIFF, while the first one is a version based on an NEF file. Addendum: Apparently it's a problem Aperture has with these TIFF files - I just added them to the library straight from disk and got the same odd color. Both Preview and Photoshop display them correctly.
