      In my opinion it’s like saying why are all old movies so good? The thing is that isn’t true. Out all the hundreds and thousands of movies created back then. Yet some were so good you watch them today. Same here. There were probably lots of videos created back then which were pretty hard to understand, but this one was so good a guy uploaded it many years later

    Rhystic Studies sent me here - I've always wanted to know more about holography and his video "The Shimmer" used this as an early reference.

    Thank you for sharing this video with us. I met Dr. Jeong, and attended his holography workshops, back in 1991, at Lake Forest University, near Chicago. He ran this very film for us, during the one of the lectures. Very cool. I really miss being able to produce holograms. I live in a house which is on a wooden foundation, which won't permit holography, due to vibrations.

      You could definitely make holograms with our kit! Just need a solid table. I've actually made holograms at a local Starbucks on one of those little tables there! That's one of the advantages of our kits, you don't need a whole elaborate set up to get holograms.

      @@LitiHolo Indeed. If I'm not mistaken, there's neoprene under the component holders? If that economic package goes through, I'll certainly put it to the test here. I no longer have the 3,000 pound concrete slab on inner tubes, but I still have all my spatial filters, and mounts, along with a 40mW HeNe. But I'd still want to test your kit in it's stock presentation. :)

      @@ruthann3190 Don't know about that, but there is an experiment, in which one can hold a reflection hologram over a steaming cuppa, for a few seconds, and the coloiur of the hologram will shift from green, to red, as the film emulsion swells, and defracts the light at a lower freqency. :)

    I had trouble understanding why it is able to record parts of the object that aren't directly illuminated by the object beam. The reason it is able to do this is because it captures the entire light field. There is some diffusion of the object beam once it meets the object, and some of the light will bounce around the entire area, with each contact of any side of the object or objects causing further phase change, which is how it obtains and records the spatial information of those angles. Obviously getting to the far end of the sides of the object will have reflected a lot of times, unavoidably losing some of the intensity each time. This is why during playback the image tends to get darker the further to the side the viewer is looking at the hologram from.
    All of the light eventually ends up at the holographic medium where the reference beam is shining and forms the interference pattern. I say eventually. It's light. For all practical reference of speed it's instantaneous.

    i am finding it hard to understand the part where it is said that a piece contains the whole...
    that one piece contains the view from that one point of reference is the more accurate statement correct?
    the dice hologram example is certainly a better example but i will keep looking for an even more pronounced example.
    Thank you for you historic and modern examples.
