[QUOTE="J-see, post: 439539, member: 31330"] At the level of noise it makes close to no difference. The RT rendering of the 64 is a bit strange and I'll have to check why it is like that. But this isn't about noise. The main difference is data but it's hard to see that in an 8 bit JPeG. Even when the shots here look identical, the difference is in the RAW data. ISO 64 Dynamic Range: <14,76Ev Tonal Range: <9,83 bits Color Sensitivity: <25,7 bits ISO 800 DR: <11,67Ev TR: <8,28 bits CS: <21,8 bits The same shot, about the same effort and without ISO I can have 1.5 times more distinguishable gray levels and more than 8 times as many distinguishable color values. And my dynamic range increase. All I have to do is NOT use ISO. [/QUOTE]
