I prefer it when the conductor follows me. It is more difficult to work with a conductor who does not listen - even if I understand that sometimes it makes sense when one person is ruling everything. But for bel canto, I have to have a conductor who listens and supports me.
When I started, my teachers told me that I had to sing Mozart, Mozart, Mozart. I said, No, I want to sing all the other stuff. If you do not push yourself, you will stay the same. Maybe some singers are happy with that, but I have to move, I have to do something new always.
I know what I want, and I know what needs to be done to make my performance better. So I do these little askings, about the lights and costumes. Its not the diva speaking. Its the artist who knows how it has to be done.
