andrea - that's really interesting. could you add the D3s to it? i'm surprised how "low" it's DR is as reported elsewhere considering how great it does in low light.
The D3s DR isn't "low" - it's right up there with the best of the cameras which were new in 2008. It's just that now things have advanced, so there are cameras which are better, largely due to trickery such as in the X-Pro1 where setting "Auto" or DR 400%" invokes the camera to reduce the sensor sensitivity (ISO) in the brightest areas and boost the sensitivity the darkest areas according to how the light hits the sensor. The result of this is some additional additional noise in shadow areas, in fact this can clearly be seen in my poppy field shot taken earlier the same morning as the shots above - just after the sun rose, only blocked by the flower itself, the greenery below was in the deepest possible shadow, which auto DR has boosted by effectively increasing ISO in those areas, and the resultant noise can easily be seen even on the web-size 1400px wide version.
The other thing I like with the Fuji is just how film-like the noise, where it occurs, can be - it looks more like irregular film grain than the usual regimented digital noise.
Without this trickery, short of doing an HDR bracket (not really possible because of the breeze blowing) this would have been rendered almost black. I know this because two years ago I tried a similar shot with the D3s and that is exactly what happened, with the sky and flower properly exposed, the shadows were all but featureless black, even after a valiant effort in ACR. The shot was OK all the same, but looked totally different to what I was after. That shot I turned into a dramatic silhouette
because lifting the shadows resulted in far too much noise, and exposing for the mid-tones to reduce that effect ended up really blowing out the sky behind the flower (bold type used to indicate that yes, I did that deliberately, and this is not an attempt to compare processing or how to do it), and is why this time around I chose the Fuji for a different result:
