Eclipse on the Beach
Explanation: As the
New Moon's shadow slid across the southern Pacific on July 11, people gathered along the white, sandy
Anakena Beach on the north side of Easter Island to watch a
total solar eclipse. The experience was captured in this tantalizing composite image, constructed from a sequence of 50 consecutive exposures. At their center is the totally eclipsed Sun surrounded by a
shimmering solar corona. From the well chosen viewpoint, palm trees appear in silhouette against a darkened sky and the faint light reflected in the water. Of course,
towering above the onlookers, at the boundaries of land, ocean,
and sky are Moai, the island's
mysterious monolithic statues.

In extremes of the image we have the Sun in its fullness and in the larger center. It is a remarkable phenomenon that makes gain size.
As for the moai have the particularity to be scanning the horizon, this time to be watching the eclipse and there image wins wealth.
Anakena is one of the few beaches where you can enjoy white sand, palm trees, turquoise waters and some moai.
All the people appointed to the beach for "Anakena" but really that's the name of a cave close to the place where King lived Hotu Matu `a when he first came to Rapa Nui. The correct name of the spectacular beach is "Hanga Roa Morie."

I'm amazed that the photo turned out so dark considering that it was made from 50 consecutive exposures. I suppose that some very dark filters were used?

I expect the landscape lighting is provided only by the single image at totality. The rest would have been taken through something like an ND5 filter, meaning that for the exposure time required for the Sun, effectively no light at all would be recorded from the surroundings.

How can I purchase a print of this photo?
Anyone know how?

Thanks Chris; That makes sense!

The foreground in this photo appears to be just outside but not during totality, as there are shadows. Whereas the sky appears to be during totality. It's a pretty photo, would like to know the specs. I did a similar shot in 2008. You have to have a filter over the camera during the partial phases and no foreground or sky is recorded during that time.

No sky?? How do you get all those sun images if you do not record the sky???
To find the Truth, you must go Beyond.

I can assure you that the corona at totality produces enough light to cast shadows that would be caught in an image like this. At least, that's the case for for the three total solar eclipses I've witnessed. It's not as dark as you might think during totality.

Hi to all:
It seems to me that is a composite image, which does not take away any merit.
On the other hand is a picture of celestial phenomena and human circumstances.
Regards
Cesar
I come to learn and to have fun.

Yea, I think it's a great image even if it is a composite...I'm just curious how the final image was produced. I've been to two so far, one cloudy. The glare off the ocean and shadows to me suggest a small portion of the sun was showing at the time of exposure of the foreground but not the sky, like the diamond ring. My eclipse experience was that it's like twilight at totality but no shadows during.

I've made a shot like this. I used a white light solar filter for the images before and after totality. That blocks something like 99.999% of the light; solar exposures through the filter are a few hundredths of a second, and nothing shows up in the image except the solar disc against a black sky. The shot at totality is unfiltered, and is exposed for a bit longer- up to a second for a bright corona, maybe less with a higher ISO setting (note that the palm trees in this image are slightly motion blurred- it wasn't a real short exposure). In any case, the scene is similarly lit to a moonlit night, so shadows are quite apparent. Stack the shots on Lightened layers in Photoshop, and you get an image just like this APOD.
