I've been trying for a long time to duplicate the look of black and white images from the early fractal books "The Beauty of Fractals" and "The Science of Fractal Images" with FractalWorks, the fractal rendering program I'm writing. These plots use a distance estimate (DE) value to plot thin filaments in Mandelbrot and Julia set plots.

See this thread for a discussion of the Distance Estimate Method (DEM) and how I implemented it.

I finally got DE working well in my app, and am quite happy with the images I'm starting to get. Here are a couple of images I've created using DEM:
