A long exposure as the fight started created this impression of movement and color.

As folks got underway in the fight, their movement created the illusion of fighting while caught in a fierce wind.

Caught in a moment of swing, this woman exhibited the expression of sheer joy at the feeling of pelting others with pillows.

A fellow with American Eagle on his chest had just completed a swing, and his smile was about to vanish as another pillow swung toward his head.

A woman had just swung her pillow as her expression of joy was captured despite being surrounded by mayhem.

Seen from above, the fight looked like an angry sea, the waves of which were a raging of pillows.

A wide eyed fellow had just targeted the camera as he was frozen by a flash. Unseen to his left (our right) another fellow was poised to hit him.

Another photographer wore mouth and nose protection and focused on a brightly colored pair pounding on each other.

One beefy fellow swung overhead and hard downward on top of someone unseen by the camera.

As the fight progressed pillows began to burst and feathers began to be spread into the air.

At its peak, the pillow fight this year filled Justin Herman Plaza to almost capacity.
