Smooth 1D Colors #13
Here is a zoom into a Misiurewicz point using accumulator colors, with linear palette re-scaling. The main fractal has a lot of "sparkles". This is the same situation as with escape count coloring, the rate of color change increases with the higher iteration count.
The accumulator color method can create color shading that more closely follows the fractal shape. With iteration counts or log-log smoothing the background is a single color, or gradually changes from the outside to the inside. See Smooth 1D Colors #6 and Smooth 1D Colors #7 for comparison.
Minor oops, I intended to use the same coordinates to contrast accumulator coloring and log-log coloring. I just realized that I have two different Misiurewicz points. I have this image prepared so I am going with it. I may follow up later with new colors for the images in the earlier posts.
Smooth 1D Colors #15
Here is the image from Smooth 1D Colors #6 reimagined with accumulator colors. Notice the "shadows" behind the fractal, and that the blue and white are gone from the background and pushed into the fractal fine detail.
Those are not real shadows. No 3D, no light, no shadow. I use the word just to describe the lighter and darker shades in the background. The different shades arise because accumulator colors is not simple escape counting, or log-log smoothing of escape counts. Orbits of nearby points may escape at the same time, but they behave differently along the way. They take different paths on the way out. Accumulator colors uses all the points in the orbit.
Smooth 1D Colors #17
Earlier, before I started this series of posts here, I had started a thread on Fractal Forums, Smooth Colors. This image is one of a series that I posted there demonstrating the visual effects that result from changing various parameters. I am not going to repost that whole series. However, I like to do color experiments on this fractal location. I will use it as a reference to jump into another coloring idea, tomorrow.
For those of you who possess a complex number plane, this picture was taken at -0.9125+.2732i, with width = 0.125.
