Re: Yes - all models since D70

It seems that the D90's RAW, for example, at all ISO and speeds, has soem extra black clipping applied, compared to the D300/s. Have you tested that (I think Gabor did some work on it)?

I haven't looked at the D90. The D300 in 12-bit mode does clip a few DN above zero, but it behaves well in 14-bit mode.

See the last link in my initial post here:
The D90 does hot pixel NR starting at 1sec.

I don't see what black clipping has to do with it, since the filter is applied to all tonal levels, not just those near black.
