The longest day of the year is today, clouds in time-lapse over Derby video.

Today 21st June 2010 is the longest day of 2010. I meant to set up my timelapse equipment to capture a full days worth of clouds in timelpase but I forgot, but you may enjoy the last video I made of clouds in time-lapse on the longest day in 2008. This video is on my Vimeo channel. Its recorded in HD, to watch it in HD you need to click on the HD is off icon then click the link that shows, fullscreen option is bottom right of the viewer....



The Longest Day, A full day of clouds in time-lapse. June 20th 2008 from Andy Savage on Vimeo.
The idea of this video was simple, I wanted to capture a whole days worth of clouds in time-lapse on the longest day of the year (20th June 2008). The sunrises in the summer are amazing but you tend to be asleep and dont get chance to see them. By means of "timed start" time-lapse I've managed to capture a wonderful sunrise which you can see at 0:23 in this video, this equates to 4.28am
I shot the sequence out of my front window in Derby, Derbyshire, UK. I did not notice the dirt on the window until after I looked at the images, oh well !

I set the software to capture and image every 14 seconds.
The first image was taken at 02:43, this is the first photo that you could start to see some daylight starting.
The last image was taken at 23:04 which was the last image with any daylight present.
The sequence is made from 5232 photographs, taken with a Canon Ixus 430.

To learn more about how the length of the day changes throughout the year see here :
http://en.wikipedia.org/wiki/Solstice

In 2010, at 7:28 a.m. Eastern Time, the Summer Solstice began, marking the first day of summer and the longest day of the year for those in the Northern Hemisphere.

The Earth, tilted on its 23.5-degree axis, is tipped closest to the Sun during the Summer Solstice while the opposite holds true for those residing in the Southern Hemisphere, for which today is the winter solstice. Today would be the shortest day of the year for them.

The Solstice does not always occur on the same day. The variation exists because our calendar has 365 days in a year, whereas an astronomical year has 365.25 days. The discrepancy is accounted for through our implementation of the leap year system, which adds an extra day to the calendar every four years
