Light Streaks — generative photography
A small selection of long-exposures of randomly generated IFS (aka Iterated Function Systems), a family of very oldskool primitive/trivial fractal functions, but which can produce a fairly wide variety of outcomes. Each image is the result of billions of iterations of a single particle being iteratively transformed (meaning the particle's current position is used as the input for computing its next position etc.) For each iteration & position a tiny amount of light is being captured, slowly revealing an image, just like a negative does in analog film photography.
Some of these images have been "exposed" (aka computed) for up to 30 mins. The smaller the amount of light captured per iteration, the smoother (less grainy) the outcome...
(For the more technical: This is one of these projects where a floating point pixel buffer _really_ makes all the difference! My exposure rate is only 0.001 per pixel per frame, some of the images use even weaker settings... That means for a pixel to become fully white is has to be visited at least 1000 times [or more])
Made with https://thi.ng/matrices (matrix transformations) and https://thi.ng/pixel ("film" capture)...
