I'd just like to automate my own workflow when setting exposure and get it
more accurate.
I come from a background of shooting slide film and with all that is
available with today's digital camera, it couldn't be easier for getting
proper exposure - simply look at your histogram and adjust as needed. Making
it any simpler would be an insult to my intelligence.

But I hear you that it would be nice to have the camera doing a more
careful metering based on the entire image, not just a small portion.
And to do that, essentially, in real time (as opposed to pre-metering,
which is what happening now)
Unfortunately, as far as I understand, today's computing capabilities are
not fast enough (at least for the expected price range of the end
product) to do the real-time metering and on the entire sensor.
I don't even know if the today's technology would be capable of doing
full-sensor pre-metering (in a reasonable time), while maintaining the
portable size of the camera and its battery(!). And that's yet before
the price discussion.
For my purposes, it doesn't need to be "real time". Use the current
metering to get the first approximation, take a shot about two stops under
exposed from that (to prevent clipping in most cases), as you read the
data from the sensor to the memory tally the data on each site into (16)
bins based on the top (4) bits. Based on that determine what percentage
would be clipping at that exposure.
It takes no more time than processing a jpeg and displaying the preview
and histogram, and I don't care if the process takes two seconds when I'm
doing static scenes, it takes me longer than that to look at the histogram
(which I wish was based on raw not JPEG data) and make the adjustment
myself.
I'd just like to automate my own workflow when setting exposure and get it
more accurate.
