A Collection of Unique Clouds
1. “Mammatus clouds over northeast South Dakota, . US. Mammatus, also known as mammatocumulus (meaning mammary cloud or breast cloud), is a meteorological term applied to a cellular pattern of pouches hanging underneath the base of a cloud. They can produce some dramatic and unusual patterns on the sky and are also associated with severe storms.”
2. “Noctilucent clouds are crystals of ice hanging around 80 kilometres high in the atmosphere that catch the light of the sun long after it has set on the horizon. Natural nacreous clouds occur at altitudes of 20-25 kilometres. The cloud in this image was formed from the exhaust of a missile launched from a distant firing range.”
3. “Flying saucer or Lenticular cloud”
4. “Von Karman cloud vortices above Alexander Selkirk Island, Chile. These clouds look like they have had a hole punched through them. In fact they are naturally occurring vortices crafted by wind patterns on the clouds. In this image these cloud vortices (swirls down left) have been caused by the peak of Alexander Selkirk Island (bottom left) disrupting wind-blown clouds.”
Can’t get enough of this stuff.
The First Photograph
La cour du domaine du Gras is not the first photograph attempted by the French inventor Nicéphore Niépce, but this June 1826 photograph featuring a pigeon house and a barn roof is one of the earliest surviving ones. It might probably be the world’s oldest surviving photograph (although Niépce’s one other photo may have been older than this). The View from the Window at Le Gras was captured at Saint-Loup-de-Varennes on a sheet of 20 × 25 cm oil-treated bitumen. To make what he called a “heliograph,” or sun drawing, Niépce’s camera obscura required an exposure time of more than eight hours, which made the sunlight illuminates the buildings in the pictures on both sides.
Niépce brought this photo to England in 1827 to display his process in the Royal Society and presented the photo later to his host, the British botanist and botanical artist, Francis Bauer. Niépce died without his recognition in 1833 and the photo slipped into obscurity after its last public exhibition in 1898. It was only in 1952 that the photohistorian, Helmut Gernsheim, was able to obtain it for his collection. It is in the Gernsheim Collection for The University of Texas at Austin since 1963.
