SPACE — On July 28, 1851, the first photograph of a total eclipse of the sun was recorded by a Prussian daguerreotypist named Johann Julius Friedrich Berkowski. Daguerreotypy is an old photographic process that uses silver-plated copper treated with chemical fumes to make them sensitive to light.
Of course, Johann Julius Friedrich Berkowski was not the first to attempt to photograph a solar eclipse. However, previous attempts have failed to show any contrast between the sun’s corona and the moon’s dark disk.
Using a small six-centimeter telescope, Berkowski captured an 84-second exposure that started just after the moon had fully moved in front of the sun. And the photo is amazing for its novelty. Source: Space.com
