Hi, I just got a new D90. Had a D80 before with no problems. I have found that most of the pictures I take of my children have a green tint to the faces area, noticable where there might be shadows. I am using the SB600 bounced off the ceiling, and have tried 3 different Nikon lenses: 17-55, 18-105, and 50 1.4. For test purposes, I set the camera to auto, set all lenses to 50mm, and took 3 pictures. All 3 show a greenish/yellow tint in the face area. I never had this problem with my D80. Any ideas on how to fix this? I cannot return the camera, as I have over the maximum allowed shutter activations for a return. Thanks.
