Solar Eclipse that happened on 15th Jan 2010 was an annular eclipse. Scientists calculated that this is the longest annular eclipse of the millennium. The eclipse could be seen in its completeness from Dhanushkodi, the nearest place to Srilanka in India. It was a working day for me, and I went out to see if I can photograph the event. Since, the eclipse was partial in Bangalore; the sun was still brighter so that my camera could not get the actual shape of the eclipsed sun. It only gave the impression of a very bright ball in the picture. I tried with the minimum aperture and maximum shutter speed in my camera (Canon Powershot S2 IS). Still I could not get the actual view. Lot of people assembled there to watch the event. One guy came with an x ray film and helped me to photograph the event. Yes, it worked. I placed the X-Ray film on top of the lens, and adjusted the aperture and shutter speed. After two or three trials, I could compute the required values for aperture and shutter speed, and got these images. Dhanushkodi is an interesting place to visit, a big tragedy happened there long before. You can read about this place in Wikipedia in the link (Dahnushkodi)
