(http://i1122.photobucket.com/albums/l540/Fractal_Ken/FestiveBuddha952.png) Min iterations = 25, Max iterations = 50 Inner Turmoil (http://i1122.photobucket.com/albums/l540/Fractal_Ken/InnerTurmoil1024.png) x in [-0.3, 0.1], y in [-0.6, -0.2]; Min iterations = 25, Max iterations = 500 Colorings are based loosely on ker2x's suggestion (http://www.fractalforums.com/programming/some-buddhabrot-questions-techniques/msg43957/#msg43957). The sharpness, particularly of the 2nd image, is due to counting pixel hits only when they occur on early iterations of an orbit. In these two pictures, pixel hits occurring on or after the 10th iteration are ignored. The min & max iteration numbers are still very important because they determine which orbits (c values) may be used. For example, in the first picture I only consider orbits which escape between the 25th and 50th iteration.

Good to see you around here again. Cheers, Title: Re: Playing with Buddhabrots Post by: kram1032 on November 22, 2012, 11:55:39 AM awesome burst of colors!

kram1032: Thanks. I used ker2x's idea of assigning overlapping ranges of iteration numbers to the red, green, and blue channels. This approach tends to create colorful pictures.
