Added, updated & simplified the growing collection of darkroom-related calculators and super happy how elegant and concise the code has turned out, making it super easy to add more of them in the future.

I think it's also another great, if minimal, example to illustrate how otherwise completely separate https://thi.ng/umbrella packages can seamlessly compose/combine to enable a reactive dataflow UI, all without the need for any virtual DOMs and/or completely over-the-top frameworks like React & co. It's also doing so via mostly JS-native data structures for declaring the UI (plain objects/arrays/iterables) and various constructs directly managing the reactive value streams, thus providing a lot more finegrained control over UI updates/timing/throttling). Any value changes done by the user only trigger specific, pin-point calculations which then result in equally specific UI updates to show new results. Any user action only ever triggers the minimum amount of work needed to reflect the new state.

The attached images show the source code of the entire main app (UI root) and one of the calculators...

Ps. Please let me know if you'd like to see more of these posts in the future. I'm tempted to launch season 2 of #HowToThing (see link below for 30 previous mini projects/tutorials) — but since this is very time consuming to produce & document these projects/examples, and because there has been _very little feedback_ to these previous projects/posts, I first need to gauge interest... Thank you! 🫶

I tested my paper and printing workflow and got some interesting curves. See alt-text for tech details.

Most interesting: grade 2 and 2.5 are virtually identical (except that grade 2 is denser). Grade 1.5 and 2 have virtually the same calculated ER. Is this due to the high-CRI LED I'm using instead of an incandescent? The no-filter curve would do interesting, possibly attractive, things to gamma. Next weekend, if I have time: check split-grade (00+5).

Your photography history post for today: by Lillian Bassman (1917-2012), “Night Bloom, Olga Pantushenkova, hat by Christian Lacroix Haute Couture, Paris,” gelatin silver print, published in The New York Times Magazine, 31 March 1996. #photography #photographyhistory #fashionphotography #darkroom #womanphotographer #womenphotographers

Excerpts from her obituary in The Guardian, written by Veronica Horwell, 16 Feb 2012: ‘Lillian Bassman wandered into fashion photography in pursuit of the happiness of constant creation. Her absorption in her work showed in every picture she took, or rather in every image she printed, for Bassman… was an exuberant experimenter in the darkroom. "In there, I felt a sense of being able to say something I wanted to say," she remarked. Her pictures are closer to those of the illustrators who shared the glossy pages of fashion magazines with photographers until the 1950s than to contemporaries such as Richard Avedon and Irving Penn. Avedon knew what Bassman was up to though, saying that she made "visible that heartbreaking invisible place between the appearance and the disappearance of things".

Bassman was a bohemian from her childhood in Brooklyn and Greenwich Village, New York, onwards. She was the daughter of Ukrainian emigres who had courted in the galleries of the Metropolitan Museum. Bassman admired the old masters, too, and was inspired by El Greco's near-monochrome, elongated portraits. Her early intention was to be a dancer, and she kept her eye for the grace in female movement that, she said, "usually passes unnoticed in everyday life".’

Photograph by Julia Margaret Cameron (1815-1879), “Julia Jackson,” 1867, albumen print, mounted on board, this print 9 7/8 x 7 7/8 in. (24.9 x 19.8 cm.), listed at Christie’s 2 Apr 2019. #vintagephotography #darkroom #PhotographyHistory #womenphotographers #womenshistory

From the lot essay: “The present lot shows Julia Margaret Cameron’s niece, a young and recently-wed Julia Jackson, modeled as an example of Victorian purity and grace. As a steady fixture in Cameron's work, Jackson appears in more than fifty portraits by Cameron, her natural beauty embodying the artist’s pursuit of ideal reality. The measured lighting of Cameron’s photographs demonstrates an intention to confront the unadorned beauty of her subjects; this particular example relies on Jackson's natural countenance to depict austere elegance. The present lot is a fine example of the manner and intention of Pre-Raphaelite paintings that informed and inspired Cameron’s work.“
