A Couple of 3D Favorites

Posted on April 14, 2011 By Tom No Comments on A Couple of 3D Favorites
Photography

I haven’t been doing much with my binocular camera setup lately.  Quite frankly, I find the dual camera system a bit awkward and clumsy.  There is a little carnival set up at Haywood Mall this weekend, and I’m hoping to take it over there for a few shots of the rides, etc. In the meantime, … Read More “A Couple of 3D Favorites” »

Cool 3D Tools

Dogwood Anaglyph

I’ve discovered a treasure trove of 3D tools. Japanese developer Muttyan has put together HUGE collection of applications for viewing and creating stereoscopic images and videos. These include side-by-side stereographs as well as anaglyphs using a variety of color and polarizing schemes.

Online since 2003, the site design looks like it’s stuck in the 1990’s, but the content is current and comprehensive, and that’s what matters.

I first stumbled onto the site looking for a way to create 3D views of Google Earth.  I had wondered if there was a way to create an off-set image that could be converted to anaglyphs.  I found Muttyan’s Stereo Google Earth page, and started exploring.

This page uses two instances of the Google Earth plugin to present side-by-side images of chosen locations.  I started with an overhead screen capture, such as this one of downtown Greenville…

Experiments with Stereo Photography

Pelham Mill Dam Anaglyph

Since I had been working some much with old stereographs and converting them into 3D anaglyphs, I wanted to try my own stereographs.  My first attempts were OK, but not great.  I was attempting to use one camera to create two images, but the results were often unpredictable.

I did learn a a trick with this process, though.  Fairly decent results can be obtained by first putting your weight on your right foot and snapping a shot, then shifting your weight to your left foot and shooting.  That gives just about the right amount of separation for a good stereo image.

Unfortunately, this process has some drawbacks.  First, it’s awkward if you want to get a shot that’s not easily taken from a standing position, say, a low show of flowers or a still life.  Also, it won’t work if there is any movement.  You need some way to snap two images simultaneously.

I did come up with a way to do just that.  I found a couple of VERY cheap cameras online.  My only criteria was that the cameras had to have at least 3 megapixels, have a tripod mount, and have a self-timer.  My solution was the Global Point Trekker camera, which cost me a little over $10 through Amazon.com (ignore the $34 price on their home website.)

Fun with Anaglyphs – Part 4

anaglyph still life

In the previous parts of this series I looked at ways of creating anaglyphs with Photoshop, both from old stereoscopic images and from a set of two images shot with a hand held camera. But what if you’ve already got a photograph and want to “fake” a 3D image? Well, I think I’ve worked out a method of doing that, too.

So far I haven’t found any tutorials online for creating fake anaglyphs in Photoshop. I did find Jim Long, who has done an excellent job of converting 2D images into 3D cyan-red anaglyphs. Jim as quite the gallery not just photographs, but also of classical art rendered both as stereoscopic images and as anaglyphs. Here’s his version of Da Vinci’s Mona Lisa:

I don’t know what process Jim is using, but he manages to maintain color on the images very well. He also has a link to a supplier of 3D glasses with one of the most extensive inventories I’ve seen.

Fun with Anaglyphs – Part 3

Photography

In the first part of this series I was stumped because I didn’t even have a pair of 3D glasses. This time I was stumped because I didn’t have a 3D camera set-up. In Part 2 I had mastered converting existing sterographic images into 3D anaglyphs using Photoshop, and now I wanted to try my … Read More “Fun with Anaglyphs – Part 3” »

In my last post I talked about discovering that the South Carolina Digital Library has a new collection of 3D images. They have taken old stereographs from the Civil War era and have converted them to anaglyphs so that they can be viewed using 3D glasses. As I was thinking about how they did this, … Read More “Fun with Anaglyphs – Part 2” »

Civil War. First Black Regiment, South Carolina 1st, Massachusetts 54th.  "Glory Regiment"

This week I was looking for some resources on the South Carolina Digital Library (www.scmemory.org) when I saw that they have a new collection online. The collection is from the USC library, and is a collection of stereoscopic images of South Carolina.

The images were taken with a twin lens stereographic camera during and just after the Civil War. Most of these are of the Charleston area, and many show the devastation of the war, with ruined buildings seeming to be a favorite topic.

These images were meant to be viewed with a stereograph viewer, similar to the one seen below:

The image card would be placed in the holder, and the off-set images merged into a 3D view in the viewer. When I was growing up we had one of these antiques and a collection of cards, and I loved looking through them.
