Kelvin Temperature

  1. The lowest Kelvin color temperature reading on my Canon 7D is 2500 Kelvin. That matches pretty well with a 40 Watt incadecent bulb. However, the color temeperature for sunrise and sunset is 2000K and for candle light it is 1850-1900 even lower is match flame at 1700K. Now some of these are pretty common shooting situations. Anybody has any idea why Canon stopped at 2500K ? Are there any Cameras in Canon's line up, or any other manufacturer that have a lower preset color temperature than 2500K ?
     
  2. In situations like fire light, sunrises or sunsets, I would normally want that warm glow -- maybe that is included in whatever logic they may have employed.
     
  3. For what it's worth, Lightroom allows adjusting as low as 2000K.
    I suspect the reason there's a lower limit is that there's basically no blue light at all in those temperature ranges, and therefore no way to get white.
     
  4. Canon's DPP also allowed to go lower on the °K scale than previous cameras (I used to set the 20D at the lowest setting for in-camera JPGs when shooting low-light scenes in theater plays, and then get even lower when converting the RAWs). Still I never had the need in the 7D, don't know if the camera range was expanded, or if I stopped needing that color temperature.
