Explanation:
Was this a lucky shot?
Although many amazing photographs are taken by someone who just happenedбto be in
the right place at the right time,
this image took skill and
careful planning.
First was the angularбscale: if you shoot too close to the famous
Arc de Triomphe in
Paris,
France,
the full moon will appear too small.б
Conversely, if you shoot from too far away, the moon willбappearб
too large and not fit inside
the Arc.
Second is timing:
the Moon only appears centered inside
the Arc
for small periods of time -- from this distance less than a minute.
Other planned features include lighting, relative
brightness,
height, capturing a
good foreground, and digital processing.
And yes, there is some luck involved -- for example,
the sky must be clear.
This time, the planning was successful,
bringing two of humanity's most famous icons photographically together for all
to
enjoy.
