Introduction to Masking

One of the most exciting features of Ultra Fractal is the ability to create layers that serve as masks 

for other layers. These layers contain areas of both transparency and opacity that allow only 

designated areas of the linked layer to be visible. This ability opens up a whole range of artistic 

possibilities that have never before been available in fractal software.

Before we get to the actual masking concept, though, let s create a new image using some of the 

skills we have learned thus far.

G     

Create a New Fractal using the Julia formula. 

G     

Click on the complex number below to copy it to the Clipboard.

 0.815 / 0.235

G     

Right click on the Julia Seed parameter on the Formula tab and click Paste Complex 

Value.

G     

Apply the Triangle Inequality Average coloring algorithm on the Outside tab.

Note that the Julia calculation formula and the Triangle 

Inequality Average coloring algorithm each have a 

Bailout parameter. This tells Ultra Fractal how many 

times to iterate the formula before designating a point 

"inside" or "outside."

Inside and outside points

In this case, the bailout setting for the Julia formula is 4 and the bailout for the Triangle Inequality 

Average coloring is 1e20   a much higher number (100 sextillion) that, for our purposes, 

approximates infinity.

G     

This coloring algorithm is intended to work best when the formula and coloring have 

matching bailout values, so let s change the Bailout value on the Formula tab to 1e20 to 

match the higher value on the Outside tab.

G     

Next, open the Gradient Editor and rotate the rotation slider to the left until the Rotation 

setting is  137.

Our first layer should look like this:

G     

In this image, we are going to name our layers by the coloring algorithm used, so Rename 

this layer to TIA.
