3D TLR !!!

About 3D TLR !!!

This group is for those producing 3D 'Free-view' (Cross-view or Parallel-view) images using a Twin Lens Reflex (TLR), square format film camera...

No cropping of non-square images.
No digital images.
No digital post-production whatsoever (besides the obvious conversion to digital and combining the 2 square images in Photoshop, or similar).
No viewing equipment required other than binocular vision.

In other words, you can put two prints in front of me at the local pub and I will be able to see your 3D magic.

If you don't know already, researching HOW to produce these images is up to you and all part of the fun.

Here is some copy that you might find useful for describing the (cross-eyed, or 'cross-view') process to your audience:

This is a ‘free-view’ (no special viewer required to see 3D!), more specifically in this case, ‘cross-view’ stereo image.

To view this image in 3D, cross your eyes until you see three fuzzy images. Then try and focus the middle image.
In getting used to the technique I found I had a tendency to over-cross my eyes at first. Try moving your eyes slowly and relax as much as possible. The image will suddenly pop out at you! Once you’ve done it the first time it gets much easier to reproduce the effect.
When you cross-view a stereo pair, the virtual 3D image in the middle appears a bit smaller than the actual image.

The sister technique to cross-view is parallel-view. With that, instead of crossing your eyes (tightening the muscles), you stare at an imaginary point beyond the image (relaxing, or loosening, the muscles). The stereo pair has to be arranged specifically for either/or. The parallel-view technique has more limitations on it usually, due to restrictions on the distance between images that can be displayed (on the computer screen, for instance). I also find it more difficult to obtain the correct focus.
