As far as
I know, this is the first picture of an analemma with an eclipse--at
least, a proper one, not an illustration. I
call it a "Tutulemma," a combination of analemma
and tutulma (pronounced to-tool-ma), the Turkish word for eclipse.
Analemma photography is a
difficult sport. At least a year of careful calculation and positioning
of a camera at a good position is necessary. And the long duration and
narrow windows of available photograpy time with many other technical
problems make it very difficult. So, I decided to make a composite.
At this point, I have to express my respect to single-film, multi-exposure
achievers of the image, starting with Dennis DiCicco and ending with
Anthony Ayiomamitis. Or should it be apologies?
My house is in Bursa, Turkey.
But the total solar eclipse of 29th March 2006 would not be visible
from home, but about 500 km south, from Antalya. So I had to calculate
the exact position of an analemma containing the total eclipse visible
from Antalya. So the aim was to find the time of day that an analemma
in Bursa would be positioned exactly the same angle as an analemma in
(or around) Antalya at 13:56 local summer time.

The solar eclipse would be
total around Antalya between 13:55-13:58 GMT+3. The calculations pointed
14:26 GMT+3 or 13:26 GMT+2. I constructed a styrofoam formwork on a
chimney on the rooftom of our apartment block, for the digital SLR to
be positioned at the intended part of the sky. And I started photography
on 17th July 2005. I took 26 pictures of the Sun from the rooftop on
these dates: 17, 28th July; 3, 14, 23rd August; 1, 11, 20, 25, 30th
September; 9, 20, 27th October; 8, 22nd November; 3, 13, 21, 28th December
2005; 9, 18, 29th January; 4, 21st February; 4, 19th March 2006. A good
spread of days, especially in Fall months. And then came the total solar
eclipse... It was my second totality, again in Turkey. (The first one
was in 1999, of course.)
After the eclipse, my day
job came in the way. I temporarily moved to a jobsite (as a civil engineer)
away from home; so I could not take any more sun pictures. What would
happen to the project? Fortunately, after the eclipse, I did not have
to take any pictures for about 3-4 weeks, as I had taken a good picture
of the Sun at the crossover point of the analemma, on 1st September
2005. Then another idea came:
My brother Cenk could take
the remaining pictures from the same spot. That he did precisely: He
took 5 pictures on 23rd April; 9, 28th May; 16th June and 2nd July.
The intervals were longer, but still good for me.
Then came the composite.
It was a time-consuming process with Adobe Photoshop 7. After that process,
the distorted images nicely fit each other. The analemma over Bursa
was ready. But my aim was the Tutulemma over Side, Antalya. So, I put
the picture that I had taken in the first minute of 3-minute-46-second
totality, at 13:56 GMT+3 to the background. After some nip-tuck, here
is the result: Tutulemma. Analemma with the beautiful total solar eclipse
of 2006.
This long explanation of
the composite is why I have to pay respect (and apologies) to analemma
photographers.
