<p>Light Streaks — generative photography</p><p>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.</p><p>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...</p><p>(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])</p><p>Made with <a href="https://thi.ng/matrices" rel="nofollow"><span class="invisible">https://</span>thi.ng/matrices</a> (matrix transformations) and <a href="https://thi.ng/pixel" rel="nofollow"><span class="invisible">https://</span>thi.ng/pixel</a> ("film" capture)...</p><p><a href="/tags/monochromemonday/" rel="tag">#MonochromeMonday</a> <a href="/tags/photography/" rel="tag">#Photography</a> <a href="/tags/light/" rel="tag">#Light</a> <a href="/tags/simulation/" rel="tag">#Simulation</a> <a href="/tags/longexposure/" rel="tag">#LongExposure</a> <a href="/tags/fractal/" rel="tag">#Fractal</a> <a href="/tags/ifs/" rel="tag">#IFS</a> <a href="/tags/generativeart/" rel="tag">#GenerativeArt</a> <a href="/tags/algorithmicart/" rel="tag">#AlgorithmicArt</a> <a href="/tags/thingumbrella/" rel="tag">#ThingUmbrella</a> <a href="/tags/typescript/" rel="tag">#TypeScript</a></p>
