I just got my Whibal white balance card today and tried it out. I used the whibal to get a test shot... then shot this image using auto white balance from the camera. The auto white balance didn't do a horrible job... but as you can see, the Whibal brought the real colors out. Auto tends to be a little on the warm side here. I didn't do noise reduction or sharpening to the auto balanced image so don't look at the softness and noise as related to the whibal shot... just to be fair. The only thing to judge here is the white balance.
First is the auto white balance... then the whibal balanced corrected image.
