The bad news: I didn't pack my camera accessories bag, giving me a seven-hour, six-band concert to shoot with just one battery to my name.

The good news: I did pack my (15-ounce) charger and my tablet, into which I'd put a PDF of my camera's user guide.

The great news: I had bothered to read enough of the user guide to know that my camera is capable of on-board battery charging. So instead of "calling in sick," I simply looked up the instructions: all I needed to do was connect a USB/micro cable between the charger and camera between band performances.

Lessons learned:

1. Keep an extra (fully charged) battery, and either an extra camera battery charger or a USB cable and wall plug adapter, in another part of your bag.

2. Thou shalt know thy camera as thyself.
