Most of the time you'll probably only have a little bit, so then you can lower the values little by little, until you're happy with the quality. The good news is that my above example here I chose for this tutorial page exactly because it had a lot of pixelation. I tried it, and ended up with something that took 21 hours! So if you have some awesome fractal image loaded, at 4000x3000 resolution, and try rendering it with Raystep Multiplier and Stepwidth limiter at 0.02, expect to wait a very long time for your render!. My first render of the above image in Mid mode took only a few seconds, whereas the above one took around 12 minutes. The lower you go with those two values, the longer the render is going to take. Still, what can we do to this to improve it a little? I tried simply rendering it in "Mid" mode: The above image, rendered in Preview mode Zoom somewhere in Amazing Box in navigator window - 20 iterationsīut then, when I clecked on view to main, and rendered the bugger in preview mode, I got this: Sometimes, it'll just be the colouring that's different, and sometimes, it's the whole shape of everything, as is the case with the example I used for this Tut page. Something else very important to note is that often, as I'm sure you've already encountered, what you see in the Navigator window is not all what comes out in the Render window. Try Video and Mid, see if the fractal changes for the better, etc) So do not give up after "Viewing to Main" once.
(Something to note is that, sometimes (really, not always) a render with "High" mode comes out looking very different (and usually much better-looking) than in "Preview" mode. As you go up in quality, using the "Video", "Mid" and "High" modes, renders take longer but the pixels start disappearing into nice smooth satisfying surfaces/curves. As I'm sure you already know, when you use the "preview" mode to render, it goes quickly, but the image is often riddled with pixels. Now before I start, let me tell you this: The better you want your image to look like, the longer it will take to render.
As an example, I zoomed into an appropriate area using the Amazing Box formula, with lots of pixelation happening along the edges and in various spots, etc.

So I'll do that - but for now, I'm going to share with you my discovery of how to improve the state of your fractal if it's full of annoying little noisy pixels. I've had this Mandelbulb 3D tutorial in my head so I forgot a little that this is a blog and I can (and should) post about anything, in between tutorial pages :) Alrighty! I'm slowing down with my posts and to all who missed me, my apologies!.
