3D Pictures of the Lake?

[Jan]

After getting my 3D glasses to view the Mars rover photos I found that there are many 3D pictures available online from all over the world.

I think it would be great to see some of our beautiful lake too!

NASA provides some directions on how to create these 3D images from regular pictures here:

There are so many great photographers contributing to Photopost I was wondering if any of you could try converting a few of your photos to 3D? I think a few of dcr's pics in 3D would be awesome!

Any thoughts?

You missed one of the crucial points in the directions on NASA's website - you need to start by taking two pictures, with the camera moved to the side before taking the second one. The subject has to stay very still between pictures. Alternatively, you can use a two-camera set-up (or a real stereo camera) so you can take both pictures at once.

There are techniques to make an artificial stereo picture out of a single flat picture, but that's a much more difficult technique, and the results are nothing like a true stereo pair.

This means that it would be hard for people to make stereo pictures of the lake out of the existing pictures on the site, but I do think it would be great to have people taking some new 3D pictures, using the shift technique the NASA site talks about.

There were also many side-by-side 3D picture cards of the Lakes Region and the White Mountains published in the late 1800's, for use in the old stereopticon viewers. Maybe people could post some scans of these old pictures.

A great place to learn more about 3D photography is stereoscopy.com.

There's an easier way to take 3D pictures which turn out much more spectacular since they can be in full color and don't require photo color manipulation. The only issue is that it takes a little bit of eye training to view them since you must force the eyes to focus on two different images - either in parallel view or cross-eyed. Examples are shown at the enclosed link in the gallery section. It still requires two images taken several inches apart.
