I found it very strange that the announcement explicitly said that flash photography was okay when we went to the Lion King show at the Animal Kingdom, when that was pretty much the only place that people were doing things where the flash might put them off (night-time parades excluded).
I don't really buy the argument that says that performers will be put off by flash. OTOH, continual flashes going off can be very annoying from an audience member's point of view, and (getting back to the topic) a focus light could be similarly annoying.
OTOH, since in many cameras it's very hard to switch it off, I guess it just needs to be dealt with regardless.
Has anyone started doing IR focus lighting?
