This GIF animation of Total Solar Eclipse 2010 is made of 99 pictures (
img_6662 to
img_6760)
shot by the author before and after 2nd contact by a Canon EOS 40D camera with a 500 mm
f/
6.3 mirror lens.
Processing:
The pictures of this animation have
3/
4 resolution.
They were rotated by 74° counterclockwise so that the point of 2nd contact appears roughly at top
and sun's equator lies roughly horizontal.
After rotation, the pictures were processed with a sigmoidal contrast function
(
),
a boost to a gamma of 2.5, and a boost of color saturation by 50% to provide best
visibility of chromosphere and prominence features.
Then they were cropped to 1280x768 pixels (in full resolution, i.e. 960x576 pixels in
3/
4 resolution),
so that only the upper half disk of sun/moon is shown to safe file size.
Each picture then got a red annotation in northeast corner with it's base name.
Then a morphed GIF animation (with 3 calculated frames between adjacent original images) of those
99 pictures was made, to produce a smooth flow.
At last, the animation was annotated by authors copyright (in green) in the northwest corner.
The built-in delay between frames is 100 ms which gives a maximum frame rate of
10 pictures/sec (depending on Your browser and computer).
It is planned, to publish a newer version of this work in near future, with additional annotation of timestamps in UTC.
