Explanation:
If you saw a total solar eclipse, would you do a double-take?
One astrophotographer did just that -- but it took a lake and a bit of planning.
Realizing that the eclipse would be low on the horizon, he looked for a suitable
place along the
thin swath of South America that would see, for a few minutes,
the Moon completely block the Sun, both directly and in reflection.
The day before totality, he visited a lake called
La Cuesta Del Viento
(The Slope of the Wind) and, despite its name, found so little wind that the lake
looked like a mirror.
Perfect.
Returning the day of the eclipse, though, there was a strong breeze
churning up the water -- enough to ruin the eclipse reflection shot.
Despair. But wait!
Strangely, about an hour before
totality, the wind died down.
This calmness may have been related to the eclipse itself, because
eclipsed ground heats the air less and reduces the amount rising warm air --
which can dampen and even change the wind direction.
The eclipse came,
his tripod and camera were ready, and so was the lake.
The featured image of this
double-eclipse came from a single exposure lasting just
one fifteenth of a second.
Soon after
totality,
the winds returned and the water again became choppy.
No matter -- this double-image of the
2019 July total solar eclipse had been captured forever.
