Plein Air Watercolor with Diane Gibson

We are pleased to have artist Diane Gibson conduct this watercolor Plein air Program for BWS. She has been a favored instructor for many years.

Plein Air painting is a wonderful addiction, a chance to be outside and to paint Maryland forests, farmyards and local villages.

The instructor, Diane Gibson, has been plein air painting in Maryland and while hiking for many years in England, France, and China.  Foremost influences on her style have included Tony Couch, Fritz Briggs, John Salminen, Tony van Hasselt, and the famed English painters, David Curtis and  Edward Seago.  

As a 40 year + member and past President of the Baltimore Watercolor Society, she believes that improvement in one’s painting involves continually taking courses whenever you can as well as painting in the studio and outside on a regular basis.  Accepting the inevitable frustration and maintaining the courage to solve a conceptual or a technical problem area in your painting is essential to success.

Diane will teach you how to: 

Plan and arrange a composition based on a scene which attracts you 

Position three values—light, medium & dark

Use a limited palette of six warm and cool primary watercolors

Use a majority of soft and a minimum of hard edges.

This one-day course will include:

  • a brief orientation lecture, 
  • a watercolor demonstration,
  • individual instruction and a group critique
