Does white balance really matter? I didn't always think so, but other people did. They don't mind telling you about it, either. After someone complained about the white balance being off in my former picture, I went and did a Custom White Balance on my camera. It's really easy to do!
Now my colors are true and my background is more acurate than before. Which only goes to show that sometimes your camera needs a little more help from you to do the job right.
