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.
