A fairly typical Mandelbrot set spiral from Seahorse valley.

This image was rendered using distance estimates to plot the neighborhood of the Mandelbrot set in black, and then using histogram-based coloring and fractional iteration values to plot the exterior in a gradient from white to red. I added a sinusoidal variation in brightness, which gives the red-white gradient a wavy look.


Maximum iterations:   5000
Center Point (real, imaginary):   -0.74519,   0.11267 i
Plot Width (real):   0.00143
