FinePix REAL 3D W3 | Fujifilm Global Two small lenses (+ two small sensor) is different compared to the panasonic approach. Interchangeable 3D Lens | Press Release | LUMIX | Digital Camera | Panasonic Global Two in one lens and: - One bigger sensor What is good? Who will win?
Thanks Joep, I'm interested in 3D. I may stay with the mft Pan camera to move into 3D. What I need is the Pan 3D lens.
And a camera to support it. . . . . . . And a television to watch it. Don't you prefer making pictures? But about the technology and application: - Effective distance between the two sensors is required to create good 3D effects, Fuji approach looks more straight forward, and simple is always better (at least that is what a big Dutch company slogan tried to make clear to me). - Post processing will be good for the computer industrie!!! But it will take time before you and I can do this practically ourself, don't you think?
So how's this going to actually work. I have an old Stereo Realist and a stereo opticon. How does it work digitally?
Looks like it takes two separate photos simultaneously from different angles. The camera has those lenses at the top that are separated by the width of the camera to create the offset in the perspective. Seems a bit similar to human vision actually. They have a demo on their site that demonstrates the final photo.
In Korea I saw a 3D show being broad casted on a normal television, it projected two 50% less wide images next to each other, but that might be just an artifact on how that television read the signals wrongly... Pansonic seems to use only one sensor, curious how the split the signal: Optically in lens [*]Spatial, see above [*]Time domain, moving shutter in lens??? At sensor [*]Spatial, see above [*]Time domain: [*]With shutter in lens, no special electronics needed in sensor [*]Angle dependet shutter in sensor Warning: I am just guessing
Joep, I get it but don't get 3D on a screen. The stereo opticon relies on each eye seeing slightly off center from one another. It's how we see, those gifted with 2 normal eyes. Back in the 60's I would understand this immediately. Now at 60, My mind is in a different place.... But I'm looking forward to learning.
Simply put, your brain uses the distance between the eyeballs to give us depth perception..hence 3D. I actually saw a production sony 3D video camera which had two lenses and two sensors. It was rediculously expensive. The way this camera worked was that the lenses and sensors were seperated by the average person's inter-pupilary distance. Because of that, the size of the lens becomes a problem without using complex prism systems which could degrade the image. The darn thing was close to 100K dollars. One of the problems with this approach is that if an individual has an IPD that is really wide or really narrow, they might have issues watching the 3D movie. http://www.photoclubalpha.com/2009/10/01/sony-invent-3d-movie-hdtv-camera/ This is the camera. It uses a main lens with a twin lens grouping after the light path is split. LOL, looks like a binoviewer.
DJ, Thanks for the explanation. Now I see the light. The brain thing.... My brains on vacation so that's why I don't get it.
In the Pentax folder the also have something 3D. - It is screwed on top of the lens and has two entrances. So should work a little like Panasonic, but 90% of single lens is used. Hmm, difficult to explain. Look here: Pentax Stereo Adapter for SLRs Can you rotate camera 90% and take pictures in portrait orientation?
With the fuji, I don't think you could. In esscence, this puts the two lenses on top of one another, and the only way we'd see 3D is if we saw the image with our head at 90 degrees. I think the only way to get a portrait orientation is to just crop.
