Step 1: What not to do
I simply stood with my back to some neutral wood panelling (a door), held my camera at arm's length, turned the lens toward myself, and squeezed the shutter release. It was quick and it was easy, but it is sub-standard.
There are several problems with this photo. The camera angle is too much lower than my eyes. Because the camera was only the length of my arm away from my face, it is proportionally much closer to my nose than to my ears and my head appears to be distorted (nose too large, ears too small). My expression is not flattering. The camera flash left a reflection on my glasses and on the finished wood behind me. It also cast strong shadows on the background. Further, I am too close to the background. The photo would also be improved if I wore a white shirt, tie, and coat.
