Many scenes have less than 11 stops of actual DR in the scene, in which case there's no 'deficiency'. Other scenes have more than 14 stops of DR, in which case all current dSLRs are 'deficient' and multiple bracketed exposures and HDR are the only way to capture the full scene DR, assuming you need to do so.
That is a very interesting perspective, never thought of that. Thanks.
I try to work with what I have, I am still far away from using my 5D3 to its limits.
