Anaglyphs
--------------------------------------Anaglyph? Let's just call it what it is, 3D. Photos that require those classic red and blue (or other combos) glasses to trick your eyes to see a 2D photo in 3D. Here is my (crappy) example:
The method is fairly simple, imagine each eye is a camera and take a picture. There are elaborate lens adapters with mirros that split and image in a single frame or use one camera to take two pictures a few inches apart (which is what I did). The real trick is to get the focal point to be right. For it to work there can only be one focal point in the picture which ends up being the center of both images. In my example above, the background works, but the glasses in the foreground are WAY out of focus. There should not be so much red and blue "shadow" in the picture.
What I'd like to do is get ahold of a couple of cheap digital cameras and rig them up so one button triggers both cameras which are spaced eye-distance apart. I'm sure someone has done this (as is the case with all ideas I seem to have) but I haven't found it yet. There are cheap digital cameras ($10) but they only seem to work on a PC, and I have a Mac. This probably isn't the place to get into it, but why are operating systems proprietary? It's like having a DC and AC electricity grid. Anyway, seems like a fairly simple project that I'd like to work on. Afterall, I did buy 150 of those blue and red 3D glasses.
Here is a simple tutorial by some people at NASA.
