How is the first one done? It seems like the cartons would fall faster than you could manually capture 2-3 images? (super cool all around, thanks for sharing)

I believe there have been camera specifically designed for this, where they have multiple horizontally spaced lenses that all take a picture at the same time, or literally just holding several cameras right next to each other and triggering them all at once

It's tech from the 80s. Look up the Nishika N8000 and Nimslo 3D.

Basically it's multiple lenses next to each other, each capturing a small slice on the 35mm film. Every lens has it's own shutter, which is triggered at exactly the same time.

This wasn't too involved and quite cheap to implement with analog tech in the 80s/90s, but if you want to do the same thing with digital there's quite a bit more to consider. Here's a cool video of someone building a digital stereo camera: https://www.youtube.com/watch?v=_aofxbH0elo

The hard part with digital boils down to: Cheap camera modules are hard to calibrate to the same parameters and sometimes impossible to set focus, so pictures look the same. And taking pictures takes quite a bit of processing power, so if you want to take 4 pictures at once it gets a bit tricky with just a cheap raspberry or similar.

Somehow the extra motion seems to reduce the illusion of depth, it just seems like a disjointed animation to me.

Intresting, I have a weak eye so rely less on stereo; these pop as much more 3d then a photo.

Same. I have amblyopia and I'm really appreciating the effect. I think people's brain with "only one" eye rely a lot more onto perceptive and parallax effect for 3D perception.

https://github.com/jyjblrd/wigglegramLens This is one option, trading ease of use and low cost for lower picture quality and less light.

Ah, might have to try that. I've been getting adverts for "proper" versions of these (eg the Dispo Parallax) but no-one seems to sells them in a M4/3 mount (and I'm not keen on using adapters.)
