I've taken photography classes since I was in high school. And I was interested in photography long before that. Let's say I've been shooting for 15 years, all of them amateur at best.
For a while, my high school courses were the only formal training I had. Easily, those were one of the more useful high school classes I took. I use that information on a daily basis. Whether I'm shooting or designing something at work, I use skills I gained from photography class every day.
One of the most important skills photography taught me often has nothing to do with photography at all. It taught me to look back. In the context of photography, they're specifically talking about the act of turning around to see the image that is behind you. There might be two sides to any story but there are many sides to any photograph.
This concept of looking back is one I try to apply to my entire life. It's a concept of self-reflection.
Thinking back now I, ironically, don't remember how they taught us to get in the habit of doing this. I just know it stuck and most of my best work has been done when I remember to look back. Whether I'm looking back at my writing and making my red pen do a lot of work or figuring out how I could've handled a particular situation better, I credit this photography habit.
Even if you're not trying to capture the perfect moment through the lens of your camera, take time each day to look back. I find this especially useful when it feels like I'm stuck in tunnel vision and not actually taking in what's going on around me.
When's the last time you looked back?
