I just downloaded three random 5DmkII samples from photographyblog, and imported them into darktable-1.1.x which has the same temperature code as git master. I got the following three Kelvin values for shots that seem to have been shot in plain daylight: 6173K 5768K 4638K So that seems like a very sensible range. Do keep in mind that all RGB->Temp conversion are basically guesswork to begin with... So it's there little point in expecting pinpoint accuracy here...
