This week I am obsessed with anaglyphs.
Have any of you ever made one?

The anaglyphs article is interesting. I didn’t realize it was that easy. The thing that really grabbed me was the linked articles on phantograms and anamorphosis (3D trompe l‘oeil.)
I never thought about how this kind of warping and unwarping is the same as what happens with shooting and projecting “anamorphic widescreen” format film which is the same principle as digitally recording and editing at different aspect ratios in the same frame size.
I also didn’t know that anamorphic lenses replaced a really cool early format (Cinerama) that used 3 synchronized projectors on a deeply concave screen that formed the foundation for IMAX today. It also had multichannel audio that had to be mixed on the fly.
It’s also interesting that digital IMAX 3D will debut in the middle of this year that will “simulate” 3D and make it very inexpensive to produce and distribute. I’m curious about whether it will fake 3D from a 2D frame or shoot in a new format.
There’s a new single projector format out now (Real D) that projects 72fps and alternates left eye / right eye angles and uses polarizing lenses to filter what your eye sees. Apparently, this is how the vast majority of old school 3D movies were shown going back to the 50’s rather than the analglyph style, despite the old meme of a theater of people wearing red/blue glasses. Of course back then it was done analog with 2 projectors, lenses, filters, etc.
Polarization is still a concept I don’t totally grasp beyond light has different wavelengths and you split them up in order to filter the spectrum. It’s also how FM radio works, how to take a photo of water without seeing the reflection on the surface, how bees know which way is up in flight, how LCD displays work, how the date of the big bang is calculated, how some underwater creatures see, and how other underwater creatures make themselves invisible to them, and is being used in the development of things like invisibility cloaks for light and sound and creating wormholes for electromagnetic waves that could be used in everything from surgery to fiber-optic 3D tv displays with pixels that would look like they were floating in air.
Even though I spent half the day reading all this, it was fun to learn. Thanks for the link.
I’m glad you got so much out of it!
I hope I can keep posting stuff that inspires you.
