 # How to use the GIMP Paint Dynamics
 The main scope is describe the guidelines to emulate some paint techniques.
 
+Basically the paint dynamic emulates the technique and the brush emulates the stain quality and 
characteristics of the medium, but this is not always true, what I am saying is: that in certain cases some 
stain marks could be alone and without paint dynamics represents a good mark for a dry medium, but with 
limitations to use effectively to paint. In general, a good paint dynamics dedicated to a paint technique, 
e.g., dry media, it could work with many stain marks also with marks thought or pulled by another medium as 
watercolor, for instance.

 ## Dry Media
 Dry Media is normally associated with drawing tools, such as *graphite pencils*, *charcoal*, *pastel* and 
*crayon*.
 These drawing tools depending of the material which is build releases onto support surface, in general 
paper, creating a characteristic mark.

 On GIMP the brush set have a small amount of parametric brushes… why reason? Sincerely I do not know, 
perhaps, many illustrators, concept artists, photographers have been accustomed to see/utilize only raster 
brushes.
 The main scope of this article is to see the misused of parametric brush on GIMP and to demonstrate how is 
possible to use the parametric brush with paint dynamics to emulate many kind of media, for instance, the dry 
media.

 ### Dry Media Experiments
 I thought to begin with classic main dry media as pencil, crayon, charcoal and pastel.
 
-I think that an unique dynamic is capable emulate practically all these dry medias. Is possible to identify 
many brushes, raster and/or parametric, that can be utilized with this paint dynamic … more opaque and darken 
is possible emulate charcoal and oil crayon … less opaque and lighter, the dry crayons and pencils.
