Colin Rich's Nightfall is a lovely twist on the old time-lapse genre, capturing the urban sprawl of L.A. at a moment of transformation. Watch the city lights sparkle to life as the sun sets, over an over, to the strains of M83's "Echoes of Mine" -- and be sure to watch it full screen in HD!

Rich describes his creative process on his Vimeo page:

I shot "Nightfall" in an attempt to capture Los Angeles as it transitioned from day to night. As you probably know, LA is an expansive city so shooting it from many different angles was critical. Usually I was able to capture just one shot per day with a lot of driving, exploring, and scouting in between but the times sitting in traffic or a "sketchy" neighborhood often lead to new adventures and interesting places.

Nightfall in particular is my favorite time to shoot time lapse. Capturing the transition from day to night while looking back at the city as the purple shadow of Earth envelopes the eastern skyline and the warm distant twinkling halogen lights spark to life and give the fading sun a run for her money- this will never grow old or boring to me.

In this piece, it was important to me for the shots to both capture and accentuate the movement of light through the day and night and the use of multiple motion control techniques allowed me to do so.
