color temperature I just recently purchased a canon 10D, which has a color temperature feature on it. I tried to read the book to see how this feature works and the effects of using it, but it was not very clear. Can some one please explain color temperature to me. How to use it, and the effect it has on the out come of the photos. Thanks!!!

I don't understand all the technical parts of temperature as it relates to photography. Temperature refers to the "coolness" or "warmness" of colors. If you use Photoshop, you have the opportunity to adjust the temperature of the colors in a photogrph. See the article at "http://www.apogeephoto.com/july2004/jaltengarten7_2004.shtml" for more info. I assume the camera allows some color adjustments in-camera.

Here's the technical things you need to know about color temperature: It is measured in Kevin degrees, with 5500°K considered normal sunny noontime daylight. 2900°K is the color temperature of incandescent household bulbs, which are very "warm" or yellow in color. 7000°-8000° is a very overcast day, which, as you probably guessed, is blue in color. In a nutshell, any degree less than 5500 starts turning more yellow, and any degree greater than 5500 begins turning more blue. Noontime sunny daylight is considered "white." Most cameras have icons to choose for sunlight, cloudy, indoors, and fluorescent. You would simply select the icon that represents your current lighting condition, and shoot away. Most cameras also have a "custom" white balance for customizing how the camera "sees" the light color (very helpful in a studio situation with strobes). Your manual will instruct as to how one sets up a custom white balance.

So if I am already using custom white balance, then I really don't have to worry about color temp. Is that correct?

You do if you move to a differently-lit scene. A custom white balance is only really appropriate for the scene in which it was set up.

I shoot a wedding last Friday, and I noticed that even though I did a custom white balance, my pictures were still kind of dark. I made the appropriate adjustments to my f-stop, but the did not help enough. It was not until I adjusted the color temperature that I got everything just right. Did that adjustment over ride the white balance???
