[QUOTE="J-see, post: 431367, member: 31330"] Just a reminder that ISO is not just about noise. It permanently affects everything in regards to quality. Everyone shoots as they like but it doesn't hurt to understand that the optimal performance of the D750 is at its native ISO of 100. The moment we start upping the ISO, we start lowering that optimal performance. If you look at tonal range as an example. At ISO 100 it can display about 9.6 bits which translates into around 800 distinguishable gray levels your RAW can display. At 1600 ISO that is 7.8 bits which is around 230 levels while at 6400 ISO you're left with 6.8 bits which is only about 110-120. [ATTACH=CONFIG]146670._xfImport[/ATTACH] The same happens to your colors and evidently your dynamic range. In the end it is up to us to decide what compromise is best for any specific shot but regardless which we decide for, none comes without a cost. [/QUOTE]
