Yes, agree. The history of the forum was what made it unique. There was a wealth of information and discussion about topics rarely, or never, seen in other publications or books from a very knowledgeable base. Martin would bring up some very interesting posts on the chemistry of holography; don't know if he looks in nowadays. I used to talk about the physics of holography. Petr, you and I talked about the eye as an electronic/computing machine. My interest in this was brought about by thinking of the hologram and the viewer as sub-components of a machine with their response functions. You may remember I asked if the eye was bandwidth limited and we carried on this discussion for a while. We talked about colour in holography, about the characteristics of exposure and how to get an idea of "enough exposure".lobaz wrote:This forum has a long history, that's why it uses quite old school backend. The best property of this forum is exactly THE history - almost everything concerning holography has been discussed here, and you can still find it here. I am not sure if it is possible to make e.g. reddit holography corner and transfer old posts there. Without this rich history, the forum means nothing.
The problem I had with Facebook (no longer have a Facebook account) is that all the older display holographers simply talked about other display holographers. They all seem to wallow in the knowing of some "famous" holographer, and whatever information these display holographers had was always justified by an "expert" and "famous" holographer. To me, this was not talking about holography, it was simply name-dropping.Just because someone is "famous" does not mean that this person is all-knowing! Also, in Facebook, I found people would simply fan their ego.
For example: Is there any artistic merit in a display hologram, simply because it's a display hologram, vis-a-vis classical art appreciation? To what do we compare it: Paintings? Sculpture? Can we transcend 3D and create "extra-3d" illusions? Is there an Escher equivalent of a hologram?
Does anyone have any interesting or creative lighting methods. Danny Bruza gave a talk on lighting at PCGG2, where he used a broken lightbulb as a diffuser.
Can you record a fractal? I don't mean the image of a fractal, but an actual fractal. Given a semi-random light field, is it possible to create a hologram that will reconstruct such a semi-random pattern.
I don't suppose any of these questions will be answered (although I hope that if a discussion does prevail, it will be ordered and amicable). But, I offer these suggestions to actually debate holography, rather than simply bring up old holographers and genuflect to them in print.
