Setting your picture’s white balance
White balance refers to the color of light in a photo. Different kinds of light—fluorescent or tungsten bulbs, overcast skies, and so on—create different color casts in your photo. White balance adjustment is done by adjusting the temperature and tint to bring the color back to what you intended. Click the lesson05_005 file, then click As Shot next to WB near the top of the Basic panel and experiment with the different white balance choices in the menu.
If you shoot in a raw format, you have more choices in the menu—the ones you typically find in your camera (they’re not available with a JPEG). Choose the one that most closely matches the lighting you shot in. You can also make your own adjustments with the Temp and Tint sliders.
If you don’t like the results, in the Basic panel, click the White Balance Selector (it looks like an eyedropper) or press W on your keyboard. Move your cursor over your image, and click an area that should be neutral in color, such as a light or medium gray (you can use the Loupe that appears to help you find a neutral color).
In this example of a picture that I took of the Golden Gate Bridge in San Francisco, I want to get rid of the yellow tinge that the original picture had. Once I get the white balance closer to what I want, I can go in and adjust the tint of the picture to get it where I really want it. The White Balance Selector tool doesn’t have to be a one-step solution, but it can certainly shave some time off the process.
