Along those lines, I'm really looking forward to the implementation of single shot HDR. If you could use digital curtains and pack 1/125, 1/500, and 1/2000 exposures into a single 1/60 shot, then you'd have a hand holdable (for most lenses) single click method of producing HDR images.
It doesn't sound that complicated to implement, does anyone know of a camera that does it already?
I'd go so far as to make use of the dual pixel architecture, just read the diodes with different amplifications, esp as. Canon doesn't have an de facto ISO-free sensor.
