Taping 3-D films
Any "3-D" style film will be a fuzzy image unless you take measures to filter the stereoscoptic nature of the projection. The reason these films are 3-D are due to the projection of two "out of registration" images show concurrently. The function of the glasses you are given to wear is to either filter out the left eye or right eye information for the appropriate eye. The difference between the images show are what the visual cortex will put back together in your brain to preceive depth. Usually the more out of registration the images are with each other the greater the depth that is preceived. This can be accomplished as simply as placing one of the glasses' lens over the camera's lens.
While annoyance of fellow guests is a consideration, I suspect the annoyance factor of taping these or other attractions isn't Disney's main concern. Removal of screaming/crying children from shows has never appeared to be a concern to any CM running a show I've observed since I began visiting back in 1976 - AND LET ME HASTEN TO ADD - nor would I ask any family member to do so. I raised two girls myself and have two grandchildren and sometimes you don't know all the facts of why someone would stay or go in a given situation. I suspect the concern is either a copyright issue of the film or has to do with the "magic" factor of the attraction. By magic factor I can understand the reason in for example Alien Encounter. So much of what went on in that attraction was in pitch darkness and depended on the psychological effect more than the special effect that had the show been done with the lights up you would have wondered what the big deal was. There really wasn't much in the darkness to tape. But an annoyance factor concern by Disney. Please! If the concern is annoyance then don't sell those twirly lightup things at Fantasmic!
As for copyright, not all Disney flim driven attractions are created equal. Most of the presentations don't tape well due to the frame rate of projection difference between the film and your video camera. It's what causes those bars across the screen. An exception would be the film in Timekeeper. While not a 3-D film it is very much a high definition film that is projected at a higher rate that will video tape quite well. You may know how vigilant the CMs there are about policing taping.
There is a real Disney's overall policy disconnect on when it is always not premitted and where. (CM oversight?) How can the Disney Magazine publish ads for zero light features of Sony handicams and sell overpriced Kodak video tape and yet say you can't tape an attraction?
A safety issue? There you have my agreement. What happens when you are taping a ride like Body Wars, it shakes the camera out of your hands, then it goes flying and hits someone, (and believe me, you have no idea how much that ride moves around unless you've been on the Behind the Magic tour). Disney is fully justified to restrict loose objects.
As for the annoyance of additional lighting, visible lighting is an annoyance to other guests and often destroys the theatrical lighting effects. The "skin" of AAs is very shinny under harsh external video lighting. As for IR, there are some instances where the ride has it's own IR lighting/cameras the CMs use to monitor the ride and guests. Usually it's enough to just use the existing IR. To fire up additional IR only blinds the monitor cameras. In some cases IR just doesn't work.
At Voyage of the Little Mermaid they take a more intelligent stance. The wrong kind of lighting destroys the magic and is a danger to the preforming CMs. However, low available light taping is welcome. How reasonable is that?
---SPOILER AHEAD---
DON'T LOOK FURTHER UNLESS YOU ARE AWARE THIS WILL REVEAL A HAUNTED MANSION EFFECT.
In the graveyard scene of the HM there is a "scrim", (a thin cheese cloth-like material), between the doombuggy you ride and the graveyard set. In some parts of the set it is used to project flying ghosts upon as you enter the scene. Otherwise it gives a hazy/foggy look to graveyard. If you blast it with external IR you just light up a spot on the scrim that the camera can't see past to the AAs. You are better off going to manual exposure settings and dialing up as much gain as you can get out of your camera without it going grainy.
