Okay I'm beginning to understand the maths a little better, thanks for your reply. Here's a better example that illustrates the difference between 1.7 and 1.8 though. In the 1.7 version below the boxIFS renders in blue to simulate water flooding the chamber. Rendering those parameters, with no changes, in 1.8 makes the entire image blue. Changing the coloring mode in 1.8 doesn't give me a workable range except for "Color map on input vector", but that gives me concentric bands of color emanating from the center of the image criss-crossing the boxIFS. I also tried the new transparency setting (cool idea!) but didn't see any difference in the image. I was expecting to see something through the blue color; am I missing something?
In 1.7:

Titel - is that the Title?
Oh yes, as a side issue, I notice the settings panel gets truncated - might have something to do with the Win7 skin I use. In the Coloring tab, the last setting "Dyn Fog on Iter." in only partially visible. I'd send you a snapshot but not sure how to attach an image in this forum. Do you need that?
I am not skilled in the mathematics you use in calculating the fractals so bear with me please. As far as I can tell, you calculate a color-value of each pixel on the object based on iteration-depth and coloring-mode etc., then map the color-values to an output-color using the pallet and its settings. If we zoom in, then we are restricting our view to a narrow band of the color-value range which shows up as a thinner vertical line on the slider range yellow bar thingy. Am I close?
