This is the answer. My work tablets are android based and taking pictures isn't supposed to be part of the workflow, but sometimes by using random button presses, you can accidentially bring up the camera/gallery (its supposed to be locked out, but our IT dept didn't do a good job of totally locking it out).

The easiest way to do it is from the lock screen, if/when it's enabled. My own gallery is full of black pictures taken of the inside of my pocket.
