One of the weak sides of the 1Dx is noise in deep shadows at base ISO.
It seems that nobody is arguing about that any more.
DXO 1Dx measurement results also show that very clearly on their measurement curves.
And I believe that nobody would be arguing that performance in this area is very critical for not just few people but for many people - for landscape photography, evening/night city shots and other sort of photography.
Though it is easy to argue that that Nikon D800 would be the better choice BUT why not to see how we could get better deep shadow SNR from 1Dx.
In one of my posts I mentioned that 1Dx has a very nice feature that could be used for that.
I will not name it now (will do at SOME next post) but here is some magic - example how it works (snapshots from LR screen - noise reduction is totally disabled )
1. First image shows 1dX shot at IS100 with EV=(-3) the Data Color noise calibration chart which was used for Noise Ninja NR S/W and PS plug-in. Shot with manual Out of Focus to blur target texture so it would not interfere with noise
2. Second one is the same with Exposure slider in LR set to +3 - looks the same as normal shot with EV=0
3. Third image is 200% crop of shot with EV=0 showing normal 1Dx ISO shadow noise
4. Fourth one is 200% crop of the EV=-3 shot with LR exposure set to +3 to raise shadows to normal level.
Level of 1Dx noise at ISO100 at -3 EV shadows is very clearly seen
And next post is little bit of magic - the similar EV=(-3) shoot from 1Dx recovered in LR - 200% crop to see the difference in SNR for random nose with the previous shot.
