However, for critical work this is not the case, as the following example shows. The subject is a black pile jacket, a faded nylon swimsuit, and a GretagMacbeth color checker chart, all sitting on a sythetic bedspread, lit by cloudy daylight. Each picture has been separately white balanced in Capture One LE using the medium grey patch on the color checker chart. The IR filter is a B+W 486. M8 firmware 1.092. Color profile is Leica M8 generic. The reproduction of the color checker chart is quite good. There is a pronounced color shift in the black pile jacket, a smaller shift in the bedspread, and no discernible shift in the faded nylon.
