I've just dabbled in alternative processes in the past, but I'm well aware of the intricacies involved in the method, from the creation of a #digitalNegative, to the preparation of emulsion, developer and toner solutions. It's no walk in the park, and Karsten has done an outstanding work, a true wizard of the art.
Thank you @toxi !

Just received the #kallitype @toxi has done from one of my photos. Oh wow! Such a beautiful thing! I'm impressed by its qualities, the level of detail it shows even in the deeper shadows and lighter tones, the richness in it's tonality and the slight, almost imperceptible, warm hue.

My nervousness is rising & palpable... The new transparencies arrived and I'm currently printing the digital negative for my first 11x15 inch (28x38 cm) kallitype. The amount of detail should be incredible at this size. Already mixed & topped up all chems/solutions, exercised my brushing skills (for applying emulsion)... The first large(r)-format printing session happening later tonight (after some Kelly Kettle evening coffee to celebrate the return of spring)...

"What is an ocean but a multitude of drops." — David Mitchell
Final tweaks (version 11 by now) of the tone curve for digital negatives for my current combination of emulsion & developer: It's pretty impressive how even minute changes to black & white points of the curve have quite noticeable impact on the rest. I've also been experimenting with reducing emulsion from 8+8+1 drops to 7+7+1 drops, but that makes that 1 drop of contrast agent ~13% stronger (too strong), also creating more grainy results.
Never underestimate the power/impact of a single drop!

Prepping a digital negative of one of my old generative art projects (from 2008) for #Kallitype printing tomorrow. The form is actually _not_ 3D, but merely the time trace of a 2D physics sim of a single line (over hundreds of frames) and using spatial velocity deltas as metric for creating faux shading...

Neither #Affinity nor #Darktable seemingly support 1D LUTs, which would have been too easy and useful for my #DigitalNegative preparation tool... Instead they both insist on using only 3D LUTs. Converting 1D to 3D takes a bit more effort, but thanks to https://thi.ng/transducers, it's still very easy...

Researching DIY solutions for preparing digital negatives for my salt/kallitype printing experiments. Working on a little curve fitting tool/library (of course using https://thi.ng/umbrella) for computing tone mapping curves derived from sample swatches (here 5% steps of gray/density). The screenshot shows 2nd - 5th degree polynomials. Looks like a quartic is more than good enough... (I know there are ready-made tools for this, but I'm learning more this way... :)
