Even for their regular tests there scenes and lighting have changed again and again.
Oh boy here we go...
* The Imatest DR test is performed using a step chart. It has nothing to do with Imaging Resource's scene tests.
* "Normalizing" has nothing to do with photographic DR and does not change it in the least.
* You, I, or anyone else can personally verify Imatest results by simply looking at a transmission step wedge shot.
* DxO measures SNR which does NOT directly translate to photographic dynamic range.
* We cannot verify DxO's results because they are run through a 'black box' algorithm.
* DxO's results generally do not correspond to results obtained using a transmission step wedge. Put another way: you can see with your own two eyes that a 70D yields more DR then they claim, and that an Exmor sensor yields less.
Put another way the 1/3 stops difference between 70D and aps-c exmor sure doesn't match what ones sees with their own eyes when out taking photos or the huge difference between D810 and 5D3....
