One of our holiday traditions is to go to a Trans Siberian Orchestra Concert. While I saw many folks pulling out point-and-shoot cameras, I didn't think my DSLR was going to be permitted. But, I did have my iPhone (6+).
The quality is not what I'd normally like to achieve in low light, but I try to remember that this kind of thing was impossible just a few years ago.
Oh, and the concert? It ROCKED! "TSO! TSO!" Anyone know how to get me a press pass so I can take real photos next year?
