Helpful explanation of the difference between Brush Flow and Brush Opacity

Yes, these values are the very same between these applications.

 

A stroke is composed of N dabs repeated along its length.

 

Flow controls single dab(*) opacity

Opacity controls the whole stroke opacity

 

 

Both can be combined achieving rich media effects

An analog comparison:

  • To have a Wash effect use Flow (Translucent)
  • To have a Glaze effect use Opacity (Transparent)

Currently AP can control Flow via tablet pressure (Flow Jitter), but not yet Opacity.

PS can control both.

 

 

In AP there is another way to achieve a credible glazing, setting the blending mode to Average.
