Now that sensitivity is as flexible as shutter speed or aperture, you need to define and operate 2x2x2 = 8 distinct modes (manual or automatic for three parameters). Rather than remember a three-dimensional matrix of modes, and which user interface control does what in each mode, I want to simply set the desired value for each of the four parameters, via dedicated controls.

What determines the auto parameter(s)?

fix shutter & aperture; auto ISO
fix shutter & ISO; auto aperture
fix aperture & ISO; auto shutter

-exposure compensation modifies the auto

-leave two on auto & the camera has to guess the priority of the remaining two.

I've not even tried the P mode but isn't that supposed to let you adjust shutter & aperture at the wheels, alternately? Does that effectively switch between shutter & aperture priority? I suspect program mode is too clever & I wouldn't know what it's doing. So your system would put it in manual unless one control was set to auto? And two set to auto would turn off the previous leaving the most recent control on auto?

Or like auto ISO, you'd set a trigger level for each control. ISO increases if the aperture is already wide open; aperture opens to keep the shutter above the minimum speed. Too many options to keep track of perhaps.
