Short 35 second video summary of a kallitype test print development from last night, showing the many different color changes a print undergoes before one can actually fully check the final result. With a trained eye, you can already make a determination quite early on, but in general each of the stages has potential to throw your expectations, sometimes tones even shift in the 24h-48h after initial drying...

Btw. This print hasn't been fully cleared by purpose and the emulsion is still partially visible in the final print. I was saving time and here was only really after tweaking the overall tone & darks...

Tricolour cyanotypes are made by separating an image into three negatives and printing them in successive layers, each toned or coloured differently. When carefully aligned, the layers combine to produce a full-colour image with depth and complexity.

In both #gumbichromate and #duotone #cyanotypes the negative is "peeled apart" and printed in different coloured negatives, then printed one colour at at time on paper, see work by:

Started creating browser-based calculators for quickly computing a bunch of recurring things in darkroom processing, so far:

Scale amount by area:
Given reference dimensions and amount, compute scaled amount needed for new target dimensions.
Example: Compute drops of emulsion needed for a new print size

Two-part solution ratio:
For a total volume of a two-part solution with a A:B target mix ratio, compute how many units are needed of both A and B.
Example: For N drops in total, compute how many drops are needed for A & B using a 1.2:1 target ratio

Solution addition:
Compute the amount of solution A (with given concentration) to add to another volume to achieve a certain target concentration (for solution A)
Example: How many extra drops of a 25% contrast agent solution are needed to achieve a 5% solution with a certain base emulsion volume

More calculators forthcoming... Feel free to ping me with any other useful formulas you'd like to have added...
