 ## The Parametric Brush and Painting Techniques
-It seems artists haven't yet realized the full usefulness and versatility of GIMP's parametric brushes, 
especially when paired with the proper dynamics. This article shows how to use parametric brushes to make 
convincing emulations of dry media such as pencil, color pencil, charcoal, chalk and pastel.

-The default shapes are round, square and diamond. Is also possible create a great variation of the shapes, 
using the different parameters to control the shape and its aspect (radius, spikes, hardness, aspect ratio, 
angle and spacing).
+The default shapes are round, square and diamond. It's also possible create a large variation of the shapes, 
using the different parameters to control the shape and its aspect (radius, spikes, hardness, aspect ratio, 
angle and spacing).
 
 Some of the advantages of parametric brushes are:
-* The stroke of the parametric brush is more sharpest and hard when we use hardness equal 1 than with the 
raster brushes,
-* Is much easy to increase/decrease the hardness via own editor or via Tool Options … instead, the .gbr and 
.gih brushes, when we increase/decrease the hardness, the stain is deformed by the blur algorithm:

brushes](https://gitlab.gnome.org/GNOME/gimp/issues/1081 "Issue #1081")

 ### Dry Media Experiments
-In 2013, I began study the dry media with parametric brushes, they are essentially the drawing tools as 
pencil, crayon, charcoal and pastel.
-I have invited also Gustavo Deveze to use my parametric brush set with 2 paint dynamics dedicated 
exclusively to dry media.

 #### Paintbrush and Airbrush Tool
-To explore the dry media effects with parametric brushes, I have revised, initially in 2013, the Pencil 
Generic Paint Dynamics to adapt better it to other dry media.
-After to work much with the variations of Pencil Generic... I have found a good compromise, but the 
methodology was complex and based only on trial and error.

-I have verified, also, that is possible to use different tools, pencil, paintbrush and airbrush, but, 
effectively the airbrush is more interesting, mainly of the Rate and Flow controls.

-In general, all size brushes are working well, but mainly between 8 ~ 64 pixels is the better compromise. 
The large brushes are interesting to covering large areas and is not possible to have a good shape, they are 
appearing a bit soft.

 ## Parametric Basic Brush Set and Paint Dynamics | Download
-The brush set, in 'B0' folder, contains the .vbr basic brushes, round and block (hard and soft versions). 
The paint dynamics are two: for the graphics tablet's stylus with tilt and not. The version with tilt is fun 
to use and is possible to emulate well the effect when you are inclining the tool in the real cases.
