Description: This is another mandelbulber hybrid. The long rendering time motivated me to search for an effective denoising method. Only 2 images were enough to remove almost all "snow".

------------------

Two layers can be enough. This can be useful if rendering time or motivation doesn't allow too much frames and lowering the raymarching step does not result in a desired outcome (many cool fractals do just dissolve when the step gets shorter).

1. First you make the images for the 2 layers. To get a little difference in noise distribution, you should add 0.1 % deviation to the raymarch multiplier before making the second layer.
 
2. Open the 2 images as layers and combine them once with brighten only and once with darken only. The 2 resulting images should be saved temporarely.

3. Denoise these 2 brightened and darkened images just enough with filters to let the annoying noise disappear.

4. Now open the denoised 2 layers and the 2 first made layers together as 4 layers. Then use the median filter. The result will be much better than the bare denoised images because the sharp contrasts survives while the noise goes.

You can expand this by combining more layers to get even better result. But the work becomes more tedious. But considering the long rendering times it may be worth it.
