It's worse than that; it uses the old fashioned red-blue glasses from the 1950s ('40s?) rather than the newer polarized glasses from the '80s (70s?). Of course, the polarized glasses will only work on a projected image so it's a good thing they used the old method.

separated images available? (Score:5, Interesting)
Does anyone know if they post the left and right images separately anywhere?
For those of us who don't have immediate access to a pair of red-blue glasses, there are other ways..
For instance, they could provide an animated gif of both images alternating, which gives you a 3D impression as if you're moving your head to the left and right. This doesn't require glasses and can be a pretty effective way to get an image to "pop out" without actually being stereoscopic.

General gripe about 3D formats. (Score:4, Informative)
So many places make these shitty R/B images available and not the seperate image pairs. There are many ways to display a 3D image, you've mentioned one. There's also free-viewing, where you cross your eyes and actually get a much better result than viewing with R/B glasses (no colour augmentation, no ghosting). And then there's my personal favourite, LCD shutter glasses (some ghosting, but no need to strain your eye muscles, and you can view a full screen).
Of course, you can create the R/B image from pairs, but not the other way around, at the very least, places that want to make 3D content available should provide both options.
I've noted the item earlier this week about a standard emerging sometime soon for 3D broadcasting. I can't wait.

Re: (Score:3, Insightful)
In the case of these images, the left image is entirely in the red bits in the image, and the right image is the sum of blue and green, so you can separate them, if you've got any image processing software. (Or did I get left and right reversed?)
Re: (Score:2)
Didn't think of that. Of course in general the above still applies to colour images that are R/B.
My photoshop skills aren't that great so the two sides ended up not having the same luminosity for some reason, whatever it works.
You'll notice the red channel (right for the left eye) looks quite full of artifacts when compared to the cyan (left for the right eye) image.

Leave it up. Work products of the U.S. Government (ie. any pictures from NASA) are public domain with a few exceptions that don't apply here. Just because someone sticks a copyright notice on something doesn't make it copyrighted.

You can find the raw images from the Surface Stereo Imager here:

Personally, my preferred method of 3D viewing is the oldskool Stereoscope [wikipedia.org].
Re: (Score:2)
I have the professional style of anaglyph glasses like NASA guys tend to use. I still have a lot of trouble making the images combine. Particularly the ones where there is a lot of seperation and thereby a lot of depth. Other ones with less depth and seperation work really well for me.

The second link in the summary leads to the NASA site, and it actually has the pictures. They're (of course) the old fashioned red/blue stereo pictures that you can use in a monitor or TV set, and not the newer polarized stereo glasses.

3-D works by using 2 cameras that are the same width across as the average width between the average human eyes (which may explain why some people can see them better than others).
So to flip it, you would essentially have to photograph both pictures again with opposite red/blue tints on the cameras.
If this was a photoshop file with 2 separate layers for each eye, you could LIKELY be able to re-color each layer (
Re: (Score:2)
In order for the 3D to work properly, the image from the right camera must wind up being viewed from the right eye, and ditto for the left. If the right image is seen by the left eye, and the left image is seen by the right eye, the perspective winds up backwards, and the 3D doesn't work.
It is the color that passes through the filter of the 3D glasses that determines which image the eye sees. Flipping the image horizontally does not change the color, so it will not
