I took a lot of great photos with the Sony 707. (I took a lot of bad ones too). The swivel back really allowed for convenient viewing when holding the camera at "interesting" levels. I do miss that feature.
I would be very proud to make such fine images. My only issue is that the tiny people on the horizon are distracting. Are these pictures about the waterfall, or the tiny people?
Is it a coincidence that they are 'round?
Good to see some actual innovation in the sensor arena. Far too much of digital photography hitherto has been in replacing film, but the opportunities in digital extend well beyond that. This is a great idea and I see no reason why they couldn't reset the pixels more than once -- just keep track of the number of resets and add enough bits to count the resets. Two bits gives you four resets, that should do it.
I would prefer one based on a helium dirigible platform.
