Short how-to video on how to set the WB (white balance) manually on the Leica M9 digital rangefinder camera so you have the correct color temperature and colors (also known as Kelvin).
With manual white balancing you shoot the i pictures "right in camera" and you are done - instead of fiddling with the files in Adobe Lightroom or Apple Aperture to find the right colors.
In the video is used a WhiBal card which is a 12% grey card that is neutral in colors (the point is not that it's grey but that it's white; and it's not the same you use for light metering, which is a 18% grey card).
You can also use a piece of white paper, grey concrete, a white wall ... anything close to neutral colors so the camera can "read" the light temperature and adjust it to daylight white white balance.
