Is it just me or does the iso 6400 photo look less noisy?

Im not sure how this can be a solution for anything, when shooting at iso 100 the image turns black so reviewing the image after the shot will be difficult.

Jimmy, this is beyond me to explain (you need to discuss with Nordstjernen, I know he can explain).

The answer is simple: There is going on some more in-camera noise reduction when using high ISO settings (and also some highlight clipping) before the raw data is written to the memory card. When using base ISO/low ISO you need to compensate for this at the post processing stage. When the noise level is pretty much the same, also the finest detail look almost identical.
