To master something is to:

1. gain control of; overcome

Photography is rarely under your control, unless you are shooting in a studio. Ask any landscape photographer, street photographer or journalist. No, you are always at the mercy of the elements.

2. acquire complete knowledge or skill in (a subject, technique, or art)

While there's some knowledge and skills involved in photography, knowing how to use a camera or how to print doesn't make you a good photographer.

In fact, technology has made photography much more accesible, exposing what has always been the most important part of this art: seeing.

No, I don't think photography can be mastered.

You can master your camera, or the printing process. But not the art. That is inside you, it's the way you see the world. You can't master yourself.

Take a look at the early work of the "masters" of photography. Yes, their images evolved over time, but their vision was always there. You won't find a point where they "became" a master.

I believe photography is a lifelong journey, there's no finish line. There's no "I've made it" in sight. No 10,000 hours.

No mastering. Just practice.
