Impressive full-color hologram examples and democratizing holography.

Your full-colour example is very impressive! I see several opportunities for currently impossible costume designs. Personally, I’ve wanted something similar — but larger — for a…
ben_w on HNHi Paul, I'm a big fan of your work democratizing holography, and I love the idea of a small-scale hologram printer. If you need any assistance with a Unity, Three.js (WebGL), or…

Objections
Plates seem expensive compared with bulk film and hobbyist grain plates.

If I already have a setup for developing film, can I use the setup with bulk rolls of film? It looks like the self-developing plates have a lower premium than I expected (if it's…

Landscape and animated holograms.
From 2 comments
Is it feasible to do landscapes or is this more for macro distances?
smhinsey on HNYou could print many frames from a video, and then if you move them fast, you'll have the illusion of a holographic video.

How many angles fit on a film and what limits size?
From 1 comment
How many angles/slices/images/whatever you call them can you fit on a single film? What is the limiting factor? What limits the form factor size?
