3D photography

Many years ago there was a device that attatched to your camera lens that split the subject into two separate images which then could be developed into a three dimentional photo which could be placed into a special viewer. Is there anything of this caliber for our modern day gigital photography?

Bud, I heard digital 3d cameras were being produced about 6 or 8 yrs. ago. Don't know what ever came of them, but I actually have an original film type 3D camera from the 70's. It uses regular 35 mm film, but I never been able to find anyone who can process the pics, though. It was so much fun back then.

Check out some of the 3D work that Uuglypher has posted. I've worked on some similar.

I believe Fuji makes (or did make) a 3D digital camera.
Hi, Budblack,
There are several ways to accomplish 3d imagery...ways to come up with two images that can be stereoptically viewed...it can even be accomplished hand-held (the "Cha Cha" technique) or even by 2D to3D conversion from a single 2D image.
Google "3D photography" and "Stereo photography" to find very informative forums on the topic.

Not the same thing. HDR refers to high dynamic range or the tonal value of an image; 3D is about dimension: height, width, and depth.

Lense add ons that let you take a 3-d image from a digital camera produce two images from a slightly different vantage point and so reproduce the stereo effect of two eyes focusing on an object from a slight different vantage point. Unfortunately, the only way you can view these two pics as a single stereo image is to use the cross your eyes method until the two images merge into one. You will see a stereo image, but your eyes will get tired. As far as I know there are no stereo image viewers out there yet. People have tried to create apps for vr headsets to view stereo pair images in stereo, but I haven't heard of any successful ones yet.

There are a couple of ways you can do it with colored filters there is a gimp script for manipulating a pair of images this does need the red/ cyan glasses.
There are the old stereoscope viewers and cards you find these on ebay from time to time. I actually have a basic 3d camera with terrible resolution but it does work. each image is only vga. You could set two camera's on a bar to get the separation. remote triggers might trigger both at the same time.
You can still buy stereo attachments for slr lenses usually not cheap.
there are 3d anaglyph lenses i found a few for pentax.

HDR has nothing to do with 3D photography (that does not mean that you can not take 3D HDR images)!
