If you compare color temperature and tint readings from the same raw file in different converters, most probably you will find the readings are different. This report is an approximation only, and there are multiple ways to derive such a report from white balance measurement data. However, white balance is not measured as color temperature and tint – it is only reported this way. In a lot of cases we see that discussions of white balance operate with color temperature and tint values. Somehow it is often forgotten that the methods of white balance calculation and application are also different between various converters, leading to differences in color renditions. When we say “render things differently”, we mean not just the obvious things like different color profiles (color transforms icc, dcp, or some other) used in different converters, and / or different contrast (tone) curves not (minor) differences in sharpening and / or noise reduction: we also mean how white balance is applied. Not just differently, in fact, but also incorrectly with certain hues.
