“… chasing everything in endless song out of one beautiful form into another”*…

From artist and photographer Doris Mitsch

In Locked Down Looking Up, Bay Area photographer Doris Mitsch captures the swirling, shapeshifting flight patterns of birds and other winged creatures: a flock of vultures creates coils and whirls between rugged mesas, crows descend toward a forest in single-file trails, and gulls congregate above the sea in lengthy lines.

The ongoing project began early in 2020 when Mitsch set up a camera outside her front door and shot consecutive images of birds flying around her home. “While everything in my life has come to a standstill, up in the air, there is still a lot going on,” she writes. She’s since traveled along the California coast and to Moab’s desert landscapes capturing similar swarming phenomena featuring vultures, gulls, and crows…

As we ponder patterns, we might send faithfully-captured birthday greetings to Thomas Wedgwood; he was born on this date in 1771. An English inventor, he was the first person reliably documented to have used light-sensitive chemicals to capture silhouette images on durable media such as paper, and the first known to have attempted to photograph the image formed in a camera obscura. His practical experiments yielded only shadow image photograms that were not light-fast, but his conceptual breakthrough and partial success have led some historians to call him “the first photographer.”

Wedgwood was the son of Josiah Wedgwood, and so the uncle of Charles Darwin (the son of Thomas’ sister, Susannah), and he was a friend and patron of Samuel Taylor Coleridge.

As we remove our sunglasses, we might spare a thought for Roger Bacon; he died on this date in 1292.  A philosopher and Franciscan friar, Bacon was one of the first to propose mathematics and experimentation as appropriate methods of science.  Working in mathematics, astronomy, physics, alchemy, and languages, he was particularly impactful in optics: he elucidated the principles of refraction, reflection, and spherical aberration, and described spectacles, which soon thereafter came into use. He developed many mathematical results concerning lenses, proposed mechanically propelled ships, carriages, and flying machines, and used a camera obscura to observe eclipses of the Sun.  And he was the first European give a detailed description of the process of making gunpowder.

He began his career at Oxford, then lectured for a time at Paris, where his skills as a pedagogue earned him the title Doctor Mirabilis, or “wonderful teacher.”  He stopped teaching when he became a Franciscan.  But his scientific work continued, despite his Order’s restrictions on activity and publication, as Bacon enjoyed the protection and patronage of Pope Clement…  until, on Clement’s death, he was placed under house arrest in Oxford, where he continued his studies, but was unable to publish and communicate with fellow investigators.

First Takes…

The very first photograph was taken in 1826 by Joseph Nicéphore Niépce, who aimed a camera obscura, which held a polished pewter plate coated with bitumen of Judea (an asphalt derivative of petroleum), out the window of the upper-story workroom at his Saint-Loup-de-Varennes country house, Le Gras. After a day-long exposure, the plate was removed and the latent image of the view from the window was rendered visible by washing it with a mixture of oil of lavender and white petroleum, which dissolved away the parts of the bitumen which had not been hardened by light. The result was this permanent direct positive picture– a one-of-a-kind photograph on pewter:

But in many ways as interesting as the first photo of anything is the first photo of a specific thing.  OObject has curated a collection of a dozen of the most interesting “firsts,” from the first photo of a human face

… to the first photo on the web

As we say “cheese,” we might recall that it was on this date in 1935 that George Gershwin signed his name to the completed orchestral score of the opera Porgy and Bess. The composer considered the 700-page work his masterpiece; many critics agree, considering this first American opera to be the finest American opera.
