David Newton, professional photographer and technical editor at Canon Professional Network, teaches you how to customize white balance settings on a Canon EOS camera. The EOS camera have 7 presets plus an auto and a custom white balance setting. You will be using the custom setting. The custom white balance will create a compromise between different types of natural or artificial light existent in the scene. You will need a white piece of paper or a paper with 18% grey color. The last one can also help you get the right exposure as well. Go to red menu after you've taken the picture and go to Custom WB registration. Choose option 1. Go to Register image on card. Next, choose white balance number 1 in the white balance menu. For RAW images it is indicated you have a custom white balance set up, so you don't have to spend a lot of time behind a computer editing the image.
