How to record in a church with domes and arches?
I was doing some listening in a Ukrainian church that has a dome and circular arches everywhere. Some of these spherical walls act like sound reflector. In other words, depending on where I stand, the sound of someone speaking from the other side could appear to be right next to me. It's a bit creepy. Otherwise, the church has a nice reverb tail and no obvious undesirable resonance.
I'm about to record a choir singing in such a church in a month. How would you go about doing it? What are the things that I should watch out for? I'm thinking of a high ORTF pair angling downwards pointing at the choir.
