Some Canon and Nikon daylight white balance colour temperatures and tints from the RawTherapee 4.0.10 User Manual. These daylight WB colour temperatures and tints are from camera input profiles: Some independent data is available in the RawTherapee 4.0.10 User Manual for comparison. RawTherapee underestimates higher colour temperatures.Īccording to the RT colorimetry document, colour temperature and tint should be reliable for daylight illuminants and above 4000 K. White balance colour temperature by RawTherapee 4.09 compared to Canon DPP 3.10 Colour Temperature WB. Findings for these two cameras were similar and for clarity of the presentation I will focus on results from the 400D. I tested both a Canon 350D and a Canon 400D. I subsequently performed Spot WB in RT version 4.09 and Colour Temperature WB in Canon Digital Photo Professional (DPP) version 3.10 for comparison. Fluorescent lamps warm white, cool white, 5000K and 6500K.įor each scene I took two photos: Auto WB and Custom WB.Daylight at sunrise, morning, noon, afternoon, sunset.I photographed the WB target of an X-Rite ColorChecker Passport in various lighting conditions: The colour temperature and tint white balance (WB) parameters in RawTherapee (RT) seemed to be unreliable and I thought some tests would help my raw photo processing. The testing methods can be applied to other cameras and other raw photo processing applications. It concludes with some advice on how to achieve a satisfactory white balance. This post presents results of some white balance testing for my Canon digital SLR cameras and RawTherapee version 4.09. A previous post introduced digital camera white balance.
