Corel Painter 105
A handy way to set brush size is to use the 
keyboard shortcut.
Adjusting Opacity
The Opacity slider controls the degree 
to which a stroke “covers” or “builds 
up” on the underlying pixels. 
80% opacity (top), and 20% opacity (bottom).
To set opacity:
1 Choose the Brush tool from the 
toolbox.
2 Choose a brush.
3 On the property bar, type a 
percentage in the Opacity box, or 
adjust the pop-up slider.
When Opacity is set low, the 
applied color is thin, allowing you 
to see through to the underlying 
colors. When set high, color being 
applied covers underlying pixels 
more completely.
Note 
•
Some methods and dab types do not 
allow for adjustments in opacity.
Setting Grain
The Grain slider controls how much 
color penetrates into the paper texture. 
Lower settings show more of the 
grain.
89% grain (top), and 12% grain (bottom).
To set grain:
• On the Brush property bar, type a 
percentage in the Grain box, or 
adjust the pop-up slider.
Move the slider to the left to reduce 
penetration and reveal more 
texture. Move it to the right to 
increase penetration and reveal less 
grain.
Note 
•
For liquid media brushes, grain 
controls the amount of “pull”. For Image 
Hose brushes, grain controls the mixture 
with the secondary color. For other 
brushes, such as airbrushes, the Grain 
slider is not available (grayed out).
