Alan Taylor at In Focus has shared his list of the Top 25 News Photos of 2015.
As I have in past years, I'll share more lists of the year's best photos as they come in.
Update: The AP shares their Top 100 News Images of 2015. Very few of these photographs show anything good, so fair warning.
Update: In Focus has published all and three parts of a three-part series of 2015: The Year in Photos.
Update: One more from In Focus: Hopeful Images from 2015. A reminder that the good in the world vastly outweighs the bad...even if it doesn't often make the news.
Update: Nature has a collection of the best science images of 2015. The WSJ presents their Year in Photos 2015.
