I went to the CiC site and read up some. It agrees with 2wheeler:
"By far the best white balance solution is to photograph using the RAW file format (if your camera supports them), as these allow you to set the WB *after* the photo has been taken. RAW files also allow one to set the WB based on a broader range of color temperature and green-magenta shifts."
My problem is multi fold. I don't do a lot of pp. even though I understand the WB theory I am having a hard time applying that to my photos under the odd lighting scenarios. I guess it just hasn't 'clicked' yet. It is when I take a picture using the WB auto and I get some strange green or yellowish tone that I can't figure out how to fix it with the WB. Not often but it still bothers me.
I have started shooting in raw+jpg so that when I get something better than iPhoto I can do more pp. but for now I want to do it 'more right' when I take the photos.
Maybe I'm being stubborn! I'm no pro just a hobbyist trying to understand more of the basics I never wanted to know before now.
As always THANKS for the replies.
