I know HN rules don’t want simple “thank you posts” but I really appreciate your thoughtful response.
In my proposal I did know the real hologram (if it worked) would be “inside out”/“depth reversed” but I left that part out. These are very difficult concepts to try to visualize and when googling them I tend to come up with academic papers (like this very interesting article) or cartoonish representations of the concepts as opposed to say pictures/video of the specific hologram properties.
I did not know setting up the hologram using two lasers to mimic the original reference source (with one from the back of the plates would give both real and virtual from the single plate (though it makes perfect sense). It just creates more fascination and questions. I really need to get my hands on some master plates and start playing to satisfy these curiosities.
