8069 is 1/3 stop more than 6400 (100 x (2^6.3333) This would be HI 0.3 on the D800 being 6 1/3 stops faster than ISO 100.10159 is 2/3 stop more than 6400 (100 x (2^6.6667) This would be HI 0.7 on the D800 being 6 2/3 stops faster than ISO 100I'm guessing your camera is set to adjust ISO in steps of 1/3 stop. Nikon may not be applying rounding to the numbers.My D800 shows HI 0.3 and HI 0.7 in both displays and in the info screens on playback when using these settings. I assume you are seeing this ISO in your post-processing software?
