That idea could be useful
My camera does have a screen, I keep the dimness at it's lowest setting and the screen itself is smaller than any modern phone, but it's not completely un-intrusive depending on the situation. In this case, no one was near me as I sat in the back. I don't like to hold up my camera/phone. I'd rather not bother anyone.
I ended up recording so much on Saturday from the back because I knew I'd be going to see DT again, tonight, from the front row where I won't be capturing much if anything at all.
