Any teacher will tell you–when you do something repetitively, you start to see patterns in what you produce. Maybe it’s a word or phrase you say often (for me, that word would be “evidently” Don’t ask. I have no idea), or maybe the first thing you notice about a person is their blank (insert, eyes, smile, arms, nose, etc.)
When I was in high school art class I almost predictably exaggerated my subjects eyes. I was so obsessed with the “window to the soul” thing that I made it the focal point of any artistic idea I was trying to represent. I did, eventually, make portrait eyes less alien-looking and much more natural, but that was always the area I concentrated on most. Back to fairies and unicorns. 
I graduated and left all the hippy-dippy stuff behind me. Ok. Not entirely. Just my paintbrushes. Mostly.
In college I probably went through 5 majors before settling on journalism, and I only stuck to that because I had been told I was a good writer (you English majors can stop shaking your heads now…ok, gloat a little longer. Ok stop). I took maybe one writing course before I threw myself into the photojournalism track. It wasn’t long after my first photo class when I started seeing a new trend in my “artistic eye”.
Feet.
God help me. Yes. Feet. I have some strange fondness of feet. A gesture or a slight smile can make a simple photo extraordinary, but I’ve found feet are so expressive and incredibly genuine.
Many people focus on hands, and don’t get me wrong, hands are beautiful, but feet are so honest and painfully unforgiving sometimes. I feel they make lovely photos.
Here are a few of my favorites. Feel free to tear them apart, offer advice, or comment as you please!
