Documentation (hardware)

[videoking]

hello everybody,
as im using more and more different content on different screenies/Monitors
etc (even audioreactive ELtapes) i realized the hard way its not as easy as it used to be to document the work. So i'll need some advice, whats the best camera in your opinion to do some documentary shots, regarding really dark darkness and wideangel vs digital dust/noise, etc....i ve tried with my ixus, but for instance, some of the less ansilumen beamers output are hardly visible later, or the EL tapes are looking much weaker.....
examples: (i was a bit stoned, sry for the shaky hand)
