Just had a thought: To read a curved focal surface with a flat sensor...

If the image was "scanned" by the sensor-read process in a circular fashion as the sensor moved towards the lens during the shot.... This would be easy with a liquid-crystal shutter near the focal "plane"
The process starting at the centre as a circle and then becoming an anulus as it radiated to the corners, we should have compensated for our curved field.

The camera could be equipped with the curve parameters of any lens. The sensor moving by piezo or moving-coil actuation may be a limit to higher shutter speeds.

Is this an equally silly idea or the germ of a better one

Simpler - curved focal-surface - lenses enabled by curve on the sensor? Cheaper lenses for novelty-fun photos maybe. However with the advent of in-camera processing able to compensate for barrel, pincushion and chromatic aberation, AND the ability to make non-spherical lenses, this seems a bad move. Swallowing a spider to catch a fly. Sure our eyes are spherical but the brain enables us to see the side of a house as a rectangle. The curved sensor, only appropriate for a given lens, limits interchangeability. It looks like a strategy for cheapness. A rush to the bottom. Pezval's lens was fast but unsharp and passed into history - so should this

On Surf's Up: Clark Little's incredible wave photography article (55 comments in total)

There was an Aussi film called Crystal Voyager made in '73 and with pink floyd as soundtrack. Shot mostly in California, it featured similar spectacles, tunnels of green glassy water rotating about the moving viewpoint and was a breathtaking experience in a big-screen cinema. The cinema had the aroma of exotic smoking mixtures floating in the air to add to the atmosphere. Despite the difficulties of hauling (what I guess was - based on the limited definition) a watertight 16mm film camera on a board the results were unprecidented and great. It's on youtube if you're keen.

Q: I wonder who this is aimed at...

A: No photographer. An air-head with no taste and excess cash - hoping to impress similar idiots.

Old man Hasselblad would turn in his grave at the absurdity.
Since when have Italians been at the forefront of camera design anyway?
Bencini, Gandolfi, Ferrania all gone long ago. This is an own-goal. Such a shame.
