Time Lapse of Full Moon rise over DC 2012

While I was photographing the Full Moon rise over DC yesterday, I tried something new.  I set up a second camera set to take a picture every 20 seconds.  I then used the timeline function in Photoshop CS6 to create this time lapse video.  With it, you can, in 5 seconds, watch 45 minutes of clouds moving across DC.  If you blink, you'll miss the moon as it was only visible for 4 or 5 minutes, the rest of time it was obscured by clouds.  Next time I try this, I'll use an interval of 5 or 10 seconds instead of 20.
