Most powerful photos of the year

As the year winds down, it's not exactly unique to look back on it via photography. Doing so here, though, is one of my more rewarding tasks. It's a chance to be a little more personal, write in my own voice and give readers a sense of what moves me when it comes to images. 

It's also overwhelming — in the best possible way — to spend weeks editing a cavalcade of stunning photographs. 

Here, then, is this year's post. (And here's last year's.)
