Watched Harry Potter IMAX 3D, only 20 minutes of which are 3D and once again the 3D process was hardly perfect. Our last 3D experience was The Polar Express, that was entirely 3D, it worked, and it was 50% cheaper 2 years ago. Decided it was worth making some more anaglyphs.
Anaglyphs can recreate more of what it felt like to be somewhere than 2D alone. They are a matter of luck and rely more on 2D techniques to simulate 3D than the stereo pair itself. Someday we may make anaglyphs from Vicacopter.
Lacking 2 decent cameras, we have built up notes on making anaglyphs with a single camera.
Use narrow depth of field to enhance depth.
Use slight camera movement for nearby objects, even less than the distance between human eyes. Use large camera movement for distant objects, over 5ft.
Align objects to point in and out instead of sideways.
Make it as bright as possible.
Objects which are to protude in front of the 3D image need 2 B fully enclosed in the borders.
Use Cyan/Red to retain color.
All images must B rectilinear. Fish eye doesn't work.
The stereo pair needs to be lined up vertically as much as possible.
