A global theme, noted in metric!
Cyanotype prints, most eclectic...
The process, inspirin’
Through ions of iron
And shine of the sun: blue aesthetic.

These are a few of the many cyanotype prints that my lab classes and I have generated over the years, in honor of World Cyanotype Day, celebrated on the last Saturday of September! Some are simple prints formed via stencils of natural images, while some depict additional efforts through symmetric effects or the use of photographic negatives. The pertinent chemical process here occurs when iron-containing compounds on photosensitized paper react in the presence of ultraviolet light (such as that in sunshine). The technique was developed in the 1840s by Sir John Herschel.

A cardinal, a pebble, the thunder…
Phenomena countless in number.
Each morning’s observing;
Perspectives, unswerving:
We walk in the middle of wonders.

A small red cardinal in a tree. The photos in this post celebrate signs of spring including birds, deer, and flowers, in honor of Earth Day. The poem itself is inspired by quotes from natural philosopher John Herschel and poet Mary Oliver. In "Preliminary Discourse on the Study of Natural Philosophy," written in 1851, Herschel states: "To the natural philosopher there is no natural object unimportant or trifling,” citing “the fall of an apple” or “the situation of a pebble” as two examples. He ultimately notes that one “walks in the midst of wonders.” In Oliver’s 2012 poem “A Thousand Mornings,” she celebrates, in part, “...morning, the light deepening, the wind easing and just waiting, as I too wait (and when have I ever been disappointed?) for redbird to sing.” Two deer looking out from the midst of the woods.

"I'm not the one that's scared." / "That's unfair."

This one has been languishing in half-finished purgatory for far too long, but I've finally completed it! YSKMB my beloved ♥️

John Herschel and Rose Stratford looking into each other's eyes on the deck of the Ellen Austin. John looks worried, but Rose is determined. In the gap between them, the Polaris star can be seen shining brightly.

scribbled a silly comic yesterday to propose a multipurpose theory for how Ahlaam already knows Rose + how John found out about the GADs
