Now let's take a look at the color controls over here on the right-hand side of the dialog box. Now the moment that I clicked with the White Balance Tool, I modified the Temperature and Tint values. And the Temperature and Tint values basically allow you to compensate for the lighting that you use to shoot the photograph. So for example, if I change the White Balance to Daylight, I am going to increase the Temperature value which trends the image more towards yellow because it's compensating for the blue light of Daylight.
So now it's sort of hard to keep track of these two guys. Basically what we have with temperature is a slider that either makes the image yellower or bluer, and then below I will sort of trend that more towards the center here so we get a more neutral image. Then we have the Tint Slider bar which trends the image more toward magenta on the right-hand side or green on the left-hand side.
So you need to remember that you have a blue-yellow control for Temperature and a green-magenta control for Tint. Still though you may have problems keeping track of which direction does which. Well, here is something to bear in mind. Think of the Temperature and Tint control as sort of being controls on a stove. When you crank them up what happens to the stuff on the stove? It gets warmer and so you are warming up the image. You are trending it towards yellow in the case of temperature or you are trending it towards magenta in the case of tint and when you take both values all the way up, when you really turn up that stove, you are making the image more red. Alright, because yellow plus magenta gives you red, so you are really trending the image more towards red. If you take those values down you are cooling the image down, you are going into refrigerator zone here, either more blue or more green or both together to make the image more Cyan if you will. Right now it's looking more green for us but that's because of the inherent colors inside this image.
Now the simplest way to just fix this image as I was showing you before is to use that Gray Eyedropper Tool, that White Balance tool, but you can also adjust these controls directly. I am going to take the temperature value for this image to about 5000 and I am going to raise the Tint value to 70. Now this is very unusual to take the Tint value this high. Usually you are going to want to take the Temperature control somewhere in the 4000-7000 degree neighborhood, this is measured in degrees Kelvin for what its worth.
But Tint you typically keep in the -10 to +10 range, in the case of this image, it's so far off, the colors were so widely-imbalance that I really needed to crank up that tint value. And you may know that you have scrubable controls in many portions of Photoshop CS2 and that means you can scrub directly on the word for example tint, as I am doing here, or if you want to scrub in larger increments at a time, you press the Shift key and you will either raise the value in increments of 10 or lower the value in increments of 10 while that Shift key is down.
Alright, I am going to take it back up into the – well, more or less 69, 70, + 70 area here which is what I want.
