Need some help here...I'm quite undecided to use between ISO800 film or ISO1600 film to cover a musical. I've not seen the stage lighting yet (seeing it only one day before the event) so I don't really know how bright it is going to be. However, the musical is going to be held at the University Cultural Centre (UCC).
The musical does not have many large movements except for some dancing in some scenes.
I'm using a relatively slow telephoto 100-300mm zoom lens (f4-f5.6) mounted on a tripod. Flash is out of the question.
For those experienced in covering muscials/concerts before, would it be advisable to use ISO1600 or just stick to ISO800?
