New #ThingUmbrella example to create a parametric, grid layout-based calibration sheet for black and white photography development. The sheet includes different swatches and gradients to measure results/responses of different exposure times and developer solutions/processes. The sheet also includes a placeholder for a custom test image to be added later...
All sheet components are pa…

Generated grayscale calibration sheet as discussed in the post. The top part of the image has three rows of grayscale swatches in different gradations, followed by a row of opposing grayscale gradients with 10% markings. Below is a column of two radial gradients: the first one white to black, the other inverted, both with 10% markings (as hemi-arcs). On the right, four bands of vertical gradients, each with a superimposed low contrast checkerboard pattern. The remaining space is reserved for an…

Also new in #ThingUmbrella: The new thi.ng/text-format-image package provides conversion/formatting for bitmap output for CLI/Terminal apps, currently only via the widely supported iTerm2 format (se…

Random #ThingUmbrella tip & tidbit about unit conversions: I've been sourcing materials for a larger contact printing setup for my kallitype process, incl. getting a much heavier ultra-clear glass plate than what I've been using so far.

#Genuary10 #Genuary2026: Polar coordinates
Circular Fold (2022), an animated circle inversion loop. Made with #ThingUmbrella.

B&W animation loop of hundreds of white circles in black hyperbolic space. The oscillating shift of the focal point is causing an constant change to the inversion/projection and the resulting constellation of circles
