The reasons for needing the first two (health and wealth) go without explanation. The third, stealth, is necessary for photography.  You simply can’t get pictures of people in public places if you make a big production about it, or (shudder) ask their permission.

To take this picture, I set the phone down sideways on the table next to me in a restaurant.  The gent at the table across from me was slightly below me, in front of a window, which was reflecting off my table (which I didn’t realize at the time).  Being such a fanatic about pictures with reflections, I nearly jumped up and down when I saw the exposure:  his head sandwiched between two reflective surfaces.

Minor enhancements to deepen the contrast and make B&W.
