If Space Odyssey 2001 was shot today, and considering its long stable shots, I think it can greatly benefit from 48fps 3D.
you're trolling . . . right?

This thread has thrown up a very interesting paradox.
On the one hand we have all the praise for what Jim Jannard and Red have done with their 4k cameras that is, justifiably imo, evident thruout these forums.
On the other hand we have the dislike and criticism of what happens when someone (Peter Jackson in this case) uses those cameras in a manner for which they were specifically designed and intended to be used, ie 4k and higher frame rates than 24fps.
Imagine the complaints if The Hobbit was not just shot at 4k / 48fps but shot and displayed at 4k / 48 fps or even 60fps, which the Dragon sensor can accomplish.
How much more fake and "video" looking would the sets, make-up, motion etc look then?
There is a very obvious and interesting ( to me at least ) contradiction here.
Do those who are unhappy with the way Peter Jackson has used his Red cameras intend to only shoot at 1080P / 24 fps if and when they purchase or rent Red equipment?
Is 1080P enough after all, despite what Jim Jannard claims?
For some people, praising the camera and damning the intended (intended by the filmaker and the manufacturer) results from those cameras is obviously fine !
Interesting.
There will be no need for RED if 24fps remains the standard, it does not take high end technology to record 8k at 24fps and i am sure that very affordable camera's will be capable of this very soon. What exactly will be the selling point for RED camera's?
Lightfield, HDR and chip size.
Add lightfield and you can choose your focus and depth of field in post. Let Autoiris handle exposure to keep the image within the goalposts and then process the lightfield so that you get a constant depth of field.
Add 120fps to the mix and you can shoot a 360* shutter and you could extract a 180* shutter (or less) at 24,30,48 or 60 fps depending on your deliverable from one clip.
And with the lightfield data + motion blur free frames you're able to extract a point cloud for 3D meshing.
Add in a 617 sized sensor and the lightfield and you can get all of the "normal" interocular distances from one frame for stereo.
The technique used by lytro is a dead end and i would not expect any real light field sensor anytime soon.
Diffraction prevents lytro's technique from ever producing high quality images. Effectively the way lytro works means that the images are computed from a bunch of images taken with tiny aperture camera's which are usually all focused on the wrong depth. No matter how many images you combine taken with the aperture set at F/64 you will still have the same diffraction limited resolution, if you use a much larger aperture lens you might have F/16 equivalent aperture sections but those images will be badly out of focus for most scenes.
Also you mention that it would be possible to extract 3D from a single lens on a large format sensor but it is the aperture of the lens that determines the range of positions that the scene is viewed from and large format lenses do not have larger apertures than full frame lenses. To have real usable results from lytro's technique would require something like a full frame 35mm F/0.5 equivalent lens giving an aperture of 70mm thus covering the interocular distance of most humans, this would likely be at least a 140mm F/2 lens on a 144x96mm sensor to allow the optical quality to be reasonable with the aperture wide open so i don't see this being a realistic solution in the future both because of the size and cost.
Instead of this I think arrays of large numbers of small camera's is a much more realistic possibility for computational photography. This would give a very large virtual aperture to allow for a large amount of motion parallax. The light from the multiple camera's could be accumulated in processing just like is done in lytro's technique, so for example 64 tiny F11 equivalent lenses can produce the low light quality of a single F1.4 lens with the depth of field of F11, it will also be possible to let all the lenses cycle through the depth range to capture sharp focus on the whole scene. I am very much looking foward to computational photography just like you are but just not using lytro's technique.
