So this may be a very stupid question but I am looking for a greater understanding of the process in creating 3d content that works with 3d vision 2.
I know of the more modern films released on 3D blu-ray are recorded with 3d equipment, some older ones are re-mastered?
is it the same with photos? are special cameras used to create the images? or can 2d images be re-mastered into 3D?
I know there are a lot of tutorials on converting video and photo for the older style anaglyph 3D. But how are full stereoscopic 3D images made?
There are two ways to make stereoscopic photos. The simplest way is to just use a 3D camera. For example, the Fujifilm W3, which simply has two offset cameras that operate in sync. The other option is to rig two cameras together, or take two offset photos with one camera. After that you can use a program like Stereo Photo Maker to put the two together, with options to automatically align and adjust the two photos so that they match up as best as possible.
For existing 2D images, I don't know of any good option to convert them to 3D. Tridef software has the option, but the results aren't any good from what I've seen. When they convert 2D movies to 3D, it's high level CG work, going frame by frame building 3D models and such.

Might as well put something useful in here:
There is a really good app if you have an iPhone, not sure if there's an android version/equivalent or not though.
Currently $2, but it does drop to $1 here and there, and was free once (that's when I got it, but I do highly recommend it for messing around with 3D pics)

There's also a lite version:

2D images can be 'converted' with simple photo editing software like GIMP but it isn't an easy process by any means, it's extremely tedious. You have to 'cut' the image into sections/layers and shift them L or R, varying degrees depending on where they are in the scene. Basically the same method as used in games that fake 3D, Crysis 3 for example.
In the Left eye version of the image anything 'into depth' is shifted left and anything that pops out is shifted to the right. Generally, however much you shift a certain section or layer one way you have to mirror that shift in the opposite eye. So for example say you shifted the background 10 pixels to the left on the L version, then on the R version it would be shifted 10 pixels to the right. As you can imagine this leaves gaps in the image which need to be cleaned up.
I'm sure there is some software out there, like what they use professionally, where you 'paint' over the image in varying shades of 'grey' (from white to black) to create a depth mask but I haven't looked into in a long time, and the bottom line is I don't even know if it's worth it. A 2D to 3D conversion that's going to be viewed on a big screen takes less separation than one that's going to be viewed on a small screen, a 1-3" gap on a 27" screen is going to be really hard to cover up.
As far as making your own 3D images from scratch without 3D equipment, it's not complicated at all. The easiest way is to take a picture and then shift the camera and take another picture, personally I made a slide to hold the camera on a tripod. There are stereo base calculators to help you figure out the separation between shots.

Once you have the 2 images you can easily combine and save them with Stereo Photo Maker [url]http://stereo.jpn.org/eng/stphmkr/[/url]
