Having a "GrayCard" reference is the best assurance that the digital pictures that you capture will have the ability to be properly White Balanced.

(Custom white balance uses an 18% gray card as a neutral reference.)

I am getting annoyed with carrying a small piece of white paper to do my white balance with. Can anyone recommend a good gray card and maybe a place to buy it online?

I find my white balance results to be excellent when using the Gray Card.

By pointing the camera at a white or gray card (angled so that it is reflecting light from the room) as a neutral reference, filling the screen completely with it, then pressing the White Balance button (or set it in the menu), the camera does its WB calculation.

To finish, we just need to move the Levels adjustment layer that contains the correct color balance over to the image without the gray card.
And so on.
