Clouds

My first attempt at a timelapse video of natural phenomena: clouds over my patio on Saturday morning. Click on the photo below for the video (0:18).

The video is composed of stills taken at 15-second intervals played at 15 fps, for an effective speed of 225×. Next time, I'll pick a shorter interval (and hopefully, more interesting clouds and scenery).

Several aircraft appear in the video, some only for the space of a single frame (less than 67 milliseconds). Still you can spot them if you look real carefully, e.g. near the end there are two specks in the 1st quadrant and a white streak in the 3rd quadrant.
