I see no trace of information loss in that statement, nor do I detect any hint of a resolution loss. Resolution and information are not the same thing. A change in the resolution of your computer screen doesn't change the amount of information contained in your harddrive, merely the way it presents the information. At least, make your distinctions sensible.
I wonder why have you called those properties "fictional"? Surely, my speculations are a bit wild, I admit, but the basis of my speculations, namely, the "whole-in-every-part" property of holograms and the other aspects attached to that, are perfectly sound. If you please, I'd like to see some evidence (books, websites, images, etc.) against the basis of my reasoning, and not bodiless comments.
An adamant disbeliever in holograms! I salute to your obstinancy. It seems that I can't convince you; here are a few websites you might be interested in.

I also recommend that you read Michael Talbot's book The Holographic Universe. It's kind of old (1991) but the information isn't too bad.

Let me try to explain again.
You have cut the film plate into many small pieces. Each piece is smaller than the original film plate, right? In creating the hologram, you need to create an interference pattern; when two beams of photons interfere, they achieve superposition and quantum entanglement - which is the basis of quantum teleportation. All that information of entanglement and superposition is recorded in the interference pattern, which is recorded on the film plate. So there's your "whole in every part". Look at it this way: the information not only exists in that little piece, but all the information exists at the same time in all of those pieces, so when you cut them, information-wise, you haven't done anything. A smaller piece will - because it is SMALLER - offer a smaller target against which the third laser will bounce and into your eyes. There are fewer photons that will be bounced back using a smaller piece - fewer photons, smaller image. The total amount of information contained in that film plate has not been changed. If you so desire you can throw out the "less clear" part, but the "smaller image" part is physically sound. I hope that you understand now. If not, just go on Google and search or holograms - there are TONS of websites on that subject out there.
I thought I've clarified my wording but I'll be happy to do it again: you'll see a smaller image - and tehrefore less clear. You see a smaller image because you are using a smaller piece of hologram to generate the entire image. Smaller piece - less clear - same information, get it? The image has shrunk and therefore you can see it less clearly, just like in common sense (although physics is pretty much never common sense these days....).
A hologram has the startling property of containing the "whole in every part", thanks to the way it was made. A hologram is made with a laser, which is split with a lens, one beam goes to a mirror, the other goes to the object of which the image you wanted on the hologram. The two beams are then brought together by using mirrors and, where they meet and create an interference pattern (I see that information on that has already been provided), which is then recorded on a film plate. To see the holographic image, simply shine another laser on the film, and the laser will reflect back according to the gratings created on the film by the interference pattern. In ordinary photography, only the amplitude of the light is captured on film; in holographic photography, both the amplitude and the phase are captured on film - which gives holograms a 3-D image, instead of a 2-D image. When the two beams interfered, they achieve "superposition" (I think that the information on that has also been provided) and are entangled via the laws of quantum mechanics. See "double-slit experiment". So the information will be "smeared" across the eentire plate, with every piece of the image entangled with every other. When you cut a small piece off, you'll see the complete image, albeit smaller (and hence less clear), because you are simply using a smaller plate! It's like your computer - if you have a 1Gb memory, you can pull out much more information than you can with a 1Mb memory, right? But, my changing the volume of your memory, you haven't changed anything about the information that the computer contains - that is in the harddrive. So, even if you cut the hologram, you'll still have the entire information present in that piece - quantum entanglement - but the image is smaller simply because you are using a smaller piece! I see no problem with that, aside from my terrible wording of it. I apologize.
If you are interested, go on Google or Wikipedia, and read for yourself.
Hopefully you guys will have ABSOLUTELY NO problem with my nickname. I'm not a physicist; I'm only a high-school student with an interest in both physics and parapsychology, and I'd like to join the fray....
(Scientific American November 2005 and Michael Talbot's book The Holographic Universe, 1991) Holographic physics takes the idea of holograms and applies it to the entire universe as a whole. The universe can be regarded as a hologram, which can store pretty much as much information as you can in a tiny space using lasers and advanced optical stuff. If you cut a hologram of an apple into small pieces, you can still regenerate the entire image of the apple with only a single piece, albeit the image is much less clear - but you can still distinguish that it's an apple. Every single piece of the hologram contains all the informatioin contained in the entire piece of hologram. This way, a person (somehow) can tap into this reservoir of information in the space-time fabric and (somehow) gain information through what we call "telepathy" or "clairvoyance" or "precognition". So no information is sent from anyone to anyone else, and thus quantum entanglement is not required, and special relativity is not violated either. If you are interested, you can come to my blog at http://mtelepathic.blogspot.com/
Also, someone said that there's ABSOLUTELY NO evidence of ESP WHATSOEVER. Please; every single SAT review book says that "ALWAYS AVOID STRONG PHRASES LIKE 'EVERY' OR 'ABSOLUTELY'". If one hasn't checked all the information about every single experiment conducted in every single nook and cranny of the world, one should never say that there is no evidence whatsoever. That is a fumblerule.
