    MkIII
    6400 ISO
    Underexposed by 2EV, and then pushed +2EV in post.

    On the left is the original and on the right is the NRed one. Its absolutely amazing. Cleanest 25,600 ISO Ive ever seen.

    Just some food for thought.

    6400+2EV=25,600. Its the same thing that camera does on any 'expanded' ISO. It just underexposes its highest native ISO (On the MkIII this is 3200) and then pushes it however many stops it has to in order to get whatever ISO equivalent youre looking for.

    Google. Its pretty common knowledge. Same thing with expanded lower ISOs. 50 is an overexposed 100 thats pulled back a stop. Thats why you lose highlight headroom and cut DR when you use 50 ISO.

    I think you're pixel peeping too much. Just get a camera that suits you well and shoot with it. All of this ISO :mb: is starting to be :ugh2:

    So what's the PP technique for achieving these results? Could one use the same processing technique on a D700 or D3 to get usable 51200 or 102400?? :eek3:

    You mean expanding on a +2EV image? That might look a lot worse than this.

    Seems like the technique that Adam has been showing is more complicated than that, or uses a separate program. I think if it was this easy to get good high ISO noise results from the Mk III, which has been out for a few years, we would have seen this before.

    I guess the highest native ISO on the D700 is 6400, so this technique could get it up to 51200

    Not exactly.

    The same guy who did all the profiling for the MkIII sensor did output on the D3/D700 sensor and you end up with a lot of problems (mainly deep red pits of noise that are indistinguishable from detail when it comes to NR)

    You can see it here

    http://www.pbase.com/feharmat/image/113252690/original

    Those are the D3 files put through the same process as the MkIII files but, like I said, the red pits are hard to distinguish from detail for the NR action.

    So...Just take it fwiw I suppose. I come away with it thinking that obviously the Canon could do a lot more and the sensor reads/outputs a higher quality signal than the Nikon. :dunno:

    But Im just a measurebator

    I actually read through that clusterfuck of a thread last night. I'm impressed with what he's done with the Mk III, but I couldn't take him seriously after reading post after post of his calling the D3 sensor garbage and "pure noise."
