My knickers are thoroughly untwisted.
I was just asking for clarity. "MFD" covers at least 100 makes/models of back; everything from a 6mp Lightphase from the 90s to an 80mp IQ180.
So you meant the P25 you shot showed less detail in the shadows then your D800. Thanks for the clarification.
Nope I did not say that at all, but the D800 does have better shadows... and I had a P25+ with a claimed dynamic range of 12+.
The IQ180 according to phase one has a dynamic range of 12.5 so we are not talking about a massive difference.
In tests I did the detail in the blacks especially where there is little color is visibly better with the D800 putting the D800 right up there as far as this goes with the newer Phase One backs.
I have also found ... as have others.... that there is a bit more detail in the blacks with the D800.http://www.circleofconfusion.ie/d800e-vs-phase-one-iq180/
In this test the D800 showed a bit more shadow detail...... and this test was done by an IQ180 owner.
A landscape photographer and instructor. I'm sure he has a good grasp on dynamic range being a landscape photographer.
The IQ180 is the newest MFB from Phase One.
From the article.
Not all of them weighted in favour of the medium format camera, though. For instance,
the D800E produced much more pleasing shadow areas on the prints of the photographs produced to test dynamic range.
Anyway let me repeat that the difference is not very big, but the important point is that you can now get great dynamic range without the heavy investment
in a medium format system and have this great dynamic range in an agile and fast system.
I live in Southern California and we get a load of crisp sunlight and I like to shoot on the beaches and in the deserts.
having great dynamic range is so helpful. Even more helpful is shooting fast exposure bracketing so as to be able to blend multiple frames
to blend scenes with say one model slightly in the shade and one model in more direct sunlight. or shooting a black and a white model in the same shot.
Fast frame rates coupled with the great dynamic range is very useful.
Even highlight recovery is bloody great with the D800. I often shoot on location which is an added cost to the cleint so it's important to bring back the elements of the background that are over exposed when using diffusion on the model.
Here is a quick test I did that shows just how much can be recovered.
Interesting if you take into account effective ISO.
