Silicon 2008 [Part 1]
Oct. 31st, 2008 01:11 amAs some of you may be aware, I put off white balance adjustment until I do post-processing — quite some time later. It is then, that I get to play the, "Which color was this originally?"-game. Sometimes I actually remember what the color of the light in the room was, but when I tweek the balance for that, the results look terrible. So in those situations I just tweek the knobs until things look good.
There are technical reasons for all of this, mostly with my camera expecting a black-body radiation curve, and getting monochromatic light instead. So, I get an overexposed red channel, and a way-way underexposed blue channel, or vice versa. (Neither of which is actually the original colors. And there are ways to work around this while shooting, but I haven't been doing it because it's labor intensive. (More precisely, I'd have to manually adjust camera settings, every time I change position. I've programmed my camera to do most of what I do automatically now, but this situations is a bit beyond my poor camera's ken.))
