  1. Preparing the digital negative & letting it dry before tonight's printing session...

    (Already inverted the photo to better see the inverted image...)

  2. 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 thi.ng/transducers, it's still very easy...

  3. Researching DIY solutions for preparing digital negatives for my salt/kallitype printing experiments. Working on a little curve fitting tool/library (of course using 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... :)
