BTW, I have a bunch of 3D images I've made on my webpage at http://www.jessemazer.com/3Dphotos.html , including some scenes from DVDs I converted to 3D (at http://www.jessemazer.com/3Dphotos.html#movies ) by taking nearby frames in scenes where the camera was panning sideways and using them as the left eye/right eye parts of a single 3D image.]]>Dec 19th 2005 2:26AMhttp://www.engadget.com/2004/08/24/how-to-tuesday-make-3-d-photos/http://www.engadget.com/2004/08/24/how-to-tuesday-make-3-d-photos/

I took some photos from the south rim of the Grand Canyon where I took the one shot, moved maybe 10 meters to the side, and took another shot. Stick the pictures next to each other, and have your eyes bring a common object together, and you've got a 3-D image. A stereoscope can help if your eyes aren't focusing correctly.]]>Dec 19th 2005 2:26AMhttp://www.engadget.com/2004/08/24/how-to-tuesday-make-3-d-photos/http://www.engadget.com/2004/08/24/how-to-tuesday-make-3-d-photos/
Alternatively, learn to cross your eyes for cross eye 3D.

Also, I prefer to not use regular cameras and use a Stereo 3D camera from the 50s, called a Realist. It has a unique look and is more fun. Here's a link to a recent roll I shot.

All it takes is two metal plates, four "arms", eight screws to hold the arms to the edegs of the plates, and a suitable screw to hold the camera to the top plate. The bottom plate should be drilled and tapped for the tripod screw. The whole thing when assembled becomes a parallelogram when viewed from the front or back.

I started Googling around and really couldn't find anything. So I started mucking around in Photoshop. I created a Photoshop action that would create an anaglyph from a single image. It's not perfect, but it does work (see link at bottom of paragraph). After running the action, you do need to nudge the Channels a bit. But, for a poorman's anaglyph creator, I think it does a decent job. If any of you try it, lemme know what ya think.

The latter is used for displaying them using two projectors and polarized lenses (see http://www.geowall.org) and for printing on Holmes cards.

You'll also find stereo pictures from various observatories around the country at the same site, but they're in twinview format

These were taken with a single digital camera and a bar, or two digital cameras synchronized with a single click, and then aligned with cheap ($100) software called Pokescope (http://www.pokescope.com). You can align, crop, and rotate stereo pairs with Pokescope, as well as effortlessly switch between anaglyph and twinview. I'd be curious to know if it actually does more than Callipygian.

Using Flash to transition between them was my idea, see Old Stone Gate on that page.

Wiggle is very cool but doesn't follow the "duh" convention of using mouseleft-mouseright to move the 'camera' and blend the images. The image should oscillate unless the user mouses into it.

When using the Flash technique, it's best to take 3 pictures (left, right, center) and blend between those. Unless you also want to do up-down.

Come on Wiggle!

Optimised color anaglyph is terrific, but most people don't have red-blue cardboard 3D glasses. It's almost an icon of geekness. For intuitive 3D impact, a stronger Wiggle can change the web.]]>Dec 19th 2005 2:26AMhttp://www.engadget.com/2004/08/24/how-to-tuesday-make-3-d-photos/http://www.engadget.com/2004/08/24/how-to-tuesday-make-3-d-photos/shifted from RED/BLUE to RED/CYAN, which facilitates seeing the full color spectrum better. This greatly improves skin tones. Paper
glasses have several serious shortcomings, the
obvious is that they get mangled in a few days!
They can't be cleaned easily, but less well
known is the fact that the red filter tends to
shift focus perception, due to it's different place in the spectrum. (Wave length in nm's)
With plastic glasses, it is possible to slightly correct this stressful mismatch with
a minimal diopter correction. When this is done the eyes of the average person can relax and
view for extended periods in comfort. A popular
line of "professional grade" plastic glasses,
called Anachrome provides glasses, so enhanced.
They also have a set of processing and shooting
protocols which help to make better color
anaglyphs. A key feature of these is the
advice to allways use less than human eye
seperation, (stereo base) in shooting or rendering CGI for stereo. The norm is about 1/2
the typical. This allows the overlaid images to partially "self-mask". In other words only a
very few pixels are showing the "carrier color"
which makes the pesky red outlines on typical anaglyphs. There are hundreds of image examples
on the website for these glasses and technique.
which is www.anachrome.com. Anachrome images
are so closely overlaid that most can be posted small on line as a regular color picture. When
a viewer wants to see the 3D detail better they
simply open the image to full size. There is a
directory of other sights that use the method in varying degrees with links. The site also
provides some tips and instructions toward
making broader spectrum, more saturadated
color anaglyphs with a series of corrective steps. To some extent, these more colorful
type of anaglyphs are being refered to as
"3D Anachromes", or A3D images.]]>Dec 19th 2005 2:26AMhttp://www.engadget.com/2004/08/24/how-to-tuesday-make-3-d-photos/http://www.engadget.com/2004/08/24/how-to-tuesday-make-3-d-photos/

These have excellent optics (front-surface mirrors,) and are simple, robust, and easy to use. I've had mine since you bought them direct from the original inventor.

All you do to make 3-D pictures is to take two photos from different angles with any camera, and then place one photograph 4 inches above the other (I tape them to a piece of paper, or just set 'em on a table.) You get stunning, photographic-quality images *in full color.*

Nothing adds interest and depth to your pictures like 3-D does. Details you'd never notice pop out at you. And you can produce effects you'd never be able to see with the naked eye. I have pictures of Mt. St. Helens taken from about 5 miles away. I moved at least 100 yards between taking pictures, and you can see the whole 3-D shape of the mountain and the crater. Really amazing stuff, and recommended for anyone who is a photo nut.]]>Dec 19th 2005 2:26AMhttp://www.engadget.com/2004/08/24/how-to-tuesday-make-3-d-photos/http://www.engadget.com/2004/08/24/how-to-tuesday-make-3-d-photos/Dec 19th 2005 2:26AMhttp://www.engadget.com/2004/08/24/how-to-tuesday-make-3-d-photos/http://www.engadget.com/2004/08/24/how-to-tuesday-make-3-d-photos/Dec 19th 2005 2:26AMhttp://www.engadget.com/2004/08/24/how-to-tuesday-make-3-d-photos/http://www.engadget.com/2004/08/24/how-to-tuesday-make-3-d-photos/"Picture Window's stereo transformation lets you prepare pairs of stereo photographs for viewing, either with red/blue colored glasses or with a standard side-by-side stereo viewer. The horizontal and vertical offsets between the two images can be adjusted for the best viewing while previewing the results on the screen."

P.S. I have taken stereo images, mostly with a Stereo Realist camera, since around 1970. You get spectacular images if you compose the picture correctly.

i've done parallel 3-D photography of a still subject (a messy room) with a *film* camera, simply stand as still as possible and take a picture with either eye, trying to keep the camera as level as possible each time.

though this method is perhaps not as solid, it does address the "human focusing" problem that twobits mentioned earlier.

dunno why you would need special software to create anaglylphs. why can't you use Photoshop's channels feature? basically, activate only the red channel and paste in the left image, then activate only the blue and green channels and paste in the right channel. with all channels active, the result should be an anaglyph. (an inverse of this method is also useful for convering anaglyphs back into two images for use as parallel/cross-eyed pairs.)]]>Dec 19th 2005 2:26AMhttp://www.engadget.com/2004/08/24/how-to-tuesday-make-3-d-photos/http://www.engadget.com/2004/08/24/how-to-tuesday-make-3-d-photos/Dec 19th 2005 2:26AMhttp://www.engadget.com/2004/08/24/how-to-tuesday-make-3-d-photos/http://www.engadget.com/2004/08/24/how-to-tuesday-make-3-d-photos/
