Tutulemma: Solar Eclipse Analemma
If you went outside at exactly the same time every day and took a picture that included the Sun, how would the Sun's position change? With great planning and effort, such a series of images can be taken. The figure-8 path the Sun follows over the course of a year is called an analemma.
Analemmas created from different latitudes would appear at least slightly different, as well as analemmas created at a different time each day. With even greater planning and effort, the series can include a total eclipse of the Sun as one of the images.
Pictured is such a total solar eclipse analemma or Tutulemma - a term coined by the photographers based on the Turkish word for eclipse. The bellow composite image sequence was recorded from Turkey starting in 2005. The base image for the sequence is from the total phase of a solar eclipse as viewed from Side, Turkey on 2006 March 29. Venus was also visible during totality, toward the lower right.

That would be fun to try. Something like http://chdk.wikia.com/wiki/CHDK installed on a canon camera could make this a fairly automated process.
ReplyDeleteInteresting, thanks John.
ReplyDeleteNow I'm daydreaming about trying this. Needed another project, yep.
ReplyDeleteI've got the CHDK firmware on an SD Card somewhere, should experiment a bit more with it. There is also an app for SmartPhones called TriggerTrap which connects (via a cable you buy from them) to your DSLR (Canon, Nikon and others) as a cable release but can also do time lapses and motion, vibration, sound triggers and more

nice capture ！thanks ！
ReplyDeleteahhh, co-ordinated time lapse.....beautiful.
ReplyDeletevery cool!
ReplyDeleteGreat content..... Thank you..... :-)
