Acoarst that will work. If you allow only one variable to 

be controlled by the cameras, the cameras would both 

behave alike. It's if you allow the cameras to govern 2 

variables [or more] that they don't act the same.  

 

With only 1 variable controlled by the cameras all they 

need to agree on is the correct exposure, and that will 

result in the same choice on that 1 variable. 

  

But let the camera govern 2 variable and now they are 

deciding more than just the correct exposure. They will  

attempt to make "aesthetic" choices about DoF, motion 

rendering, etc ... which are subjective decisions and so 

different models may be programmed differently to get 

the same histogram via different combinations of those

2 or more camera-governed variables. 

 

The problem here is that a user wants to relinquish user

control of 2 or more variables. Clearly if the user allows

only 1 variable to be controlled by the cameras then the 

cameras would behave alike. It's a contrived complaint  

in that the user does not welcome the simple solution.

Surely the art of photography is that the photographer controls the camera and not the other way round. Otherwise one may as well set the camera to automatic, where it controls all parameters and one uses it as a point and shoot camera.I would take issue when you say 'Clearly if the user allows only 1 variable to be controlled by the cameras then the cameras would behave alike'. No, they should behave alike, but not necessarily.  One would have to test this, as the electronics of the two models may be different.

No. One does NOT hafta test for that.  

  

The electronics can be as different as fire and water, but if 

the histograms are to be alike then the two cameras MUST 

adjust that one single camera-governed variable absolutely 

alike. If OTOH both histograms are NOT alike, one or both 

of the cameras is malfunctioning.

"Surely" that is what led you astray. 

  

There is art. And there is photography. And they can even 

co-exist within the same endeavor. But they CO-exist ... as 

two separate things. Neither is a thing "OF" the other. It's 

not just a semantic nit-pick. Language shapes ideas. "Art" 

is in the mind of the practitioner. "Photography" is applied

physics and engineering. Controlling the machine is not an

an art. It's just a skill. Thaz why various machines can also

control themselves to a certain degree.
