I love these zooms, especially the ones like this one that show really beautiful and somewhat unusual shapes. I have previously used Pauldelbrot's (from Fractal Forums) colouring algorithms for UF zooms and have been thrilled with the smooth, silky results - have you tried?
Really glad you do I really love unusual shapes which are that you may obtain when you you perform Julia morphings (a special way of decide where to zoom). All of those in my recent series are extremely centered, which of cause not is "obligatory". An interesting thing, when you have them such centered, is that the nearest mini Mandelbrot always is to be found in the center. That even if the center is very tiny with complicated structures surrounding
As for the coloring I almost always use the most basic, counting the number of iterations which anyhow may give very smooth coloring if you use the gradient map in "certain ways". Sometimes I think too much spectacular coloring methods takes away the attention to the fractal pattern(s). But all my fractals are published under Creative Common License and the parameter files included so you are welcome to run them and play around with them and even publish them if you link back to the original and also publish the new parameter file
Actually that's a great idea, I hadn't thought of that, thanks! I haven't posted a fractal in many years but perhaps I'll fire up UF again and take one of your parameter sets for a spin! I'll keep you posted :-)
