Jan 15, 2015 at 1:44 comment added Iliah Borg @mattdm, Exposure Bias tag 0x9204 in EXIF standard is specified as signed rational, that is represented by 2 numbers forming a fraction. Nikon are using '6' as denominator. 1/12 is internal calibration by the way.
Jan 15, 2015 at 0:59 comment added Michael C Probably because the cameras that do it this way have exposure bias steps that are set at 1/6 stop. By stating it as 12/6, it is easy to see the photographer moved the EC dial 12 clicks. If the camera displayed it as 6/3, then we would know the user had 1/3 stop steps selected when the photo was taken.
