The images in this group were created using a variety of equations, most involving transcendental functions. The colormap for these images consisted of two color ranges, each range varying in intensity linearly from light to dark. Which range was used for a particular pixel depended on whether the number of iterations at bailout was odd or even. The angle formed by a line joining the last two points in the orbit and the real axis was computed. The absolute value of this angle was converted to a colormap index in the proper color range, and the pixel was plotted using that color. Here are a few images (480 x 640 x 256 colors) selected from Mr. Carlson's very large collection.
