I use a Nikon D70s. Been shooting in M mode with white balance on Automatic. This setting measures color temerature between 3500k and 8000k. I was reading about how this might not be adequate for interior photo's, which tend to fall closer to 3000k. Today I decided to try Nikon's setting for Incandescent white balance for a couple of my real estate photo shoots. All I can say is that I'm glad I shot a second set of images at Auto because Incandescent made everything BLUE I've noticed from time to time that my images can run a little warm, but I can't see how I would ever want to use that setting again... I shoot in Jpeg <ducks for cover>, so optimizing on the Mac isn't a great option. I suppose if I ask what the pro's do, the answer will be to shoot in RAW. Are there any other options for fine tuning on the camera when shooting in Jpeg?
