Canon 5D Mark III White Balance Test Raw Sample Images

Did some tests to check how well the Auto White Balance works on the new Canon 5D Mark III.  Raw sample images are provided along with JPEGs processed through DPP Ver 3.11.10.0.  Canon cameras always seem to have a hard time with AWB and looks like the new Canon 5D Mark III is no exception to this fact.  I tested three different bulbs (2 compact flourescent and 1 incandescent) with both a white and black background.  I tested AWB, custom white balance, and also tungsten for the incandescent bulb.  The CFL bulbs were rated at 2700K and 6500K for their color temperature.  All shots were taken at ISO 400 with the Canon EF 70-200mm f/2.8L IS II USM Telephoto Zoom Lens set to aperture priority mode f/5.6.  Shutter speed was allowed to adjust to whatever the metering system decided it needed to be since the bulbs were of different brightness.

It’s fairly clear from this test that the AWB has a tough time with a light source that’s a warm color temperature.  The cooler color temperature light source (CFL 6500K) it was able to get the colors close to the custom white balance, but for warm color temperature light it’s way off on the AWB.  Maybe one day Canon will come out with a camera that doesn’t have this issue.

  1. Thank you. This corroborates my experience. I was starting to think that it was just me or my copy of the camera. I tweaked the settings on WB Shift to B2,M1, and it seems to fix AWB, at least in my initial informal test.
