It's a short demo of what are the capabilities of the 250MP prototype with a very long lens. Apart a lingering doubt about the very issue of the so large number of photosensors (and the capability of current lenses to resolve them), it's an interesting testbed: landscape details from very long distances (about 20km). You need a crystal clear air, but then you have turbulence. Now, there's the mention of a "turbulence remover" facility made by Canon.
I'm very curious about that. I know that there is existing software, used by specialised astro-photographers, to get rid of atmospherical artefacts - typically they use multiple frames, they evaluate the quality in some way, they auto-align frames and do averaging to improve the quality. It's the first time, AFAIK, that such a software is advertised for general purpose photography. Also, there are a few things that are puzzling: AFAIK, this post-processing is extremely CPU intensive and doesn't run in real-time (unless there's ad hoc hardware); but the final video with the woman waiving hands from the Tour Eiffel has such a low impact of turbulence that it should have been processed in some way...
What do you think?
