Sketching

Hi Folks: sorry about my absence but have been out along the Washington and British Columbia coastal communities doing workshops on various topics, including tsunami preparation. Another day on that. I have had a number of people asking what to do if they are not experienced or confident about pencil sketching.  good questions.
Some instructors will say that sketching is not critical to watercolor in that a few lines are sufficient to provide enough guidance for a painting study. Well and good if you are very experienced.  I think that the bottom line is__learn how to sketch!
Sketching for watercolor painting varies as much as the methods of watercolor painting. Realism painters may sketch in a lot of detail whereas impressionists may reduce the amount of detail, as i do, and sketch in mostly shadow shapes.  Charles Reid and Ted Nuttel, both impressionists, sketch in very detailed fine line methods. Here are some guides:

Teach yourself (assistance is always helpful like workshops): start with contour drawing--painting what you see not what you think you see (from memory); read Betty Edwards' DRawing on the Right Side of the Brain, section on pure and modified contour drawing. ANYONE CAN DO THIS AS IT SIMPLY TAKES PRACTICE LIKE EXERCISING A MUSCLE--DEAL WITH YOUR FEARS AND JUST DO IT!
i do not recommend sketching with perspective estimation as you will experience more distortion than contour drawing.
gesture drawing: gesture drawing looks for the key movement aspects of an object in composition and limits the sketch to a few gestural lines.
shadow sketching: this is essentially what i do--look for the shadow shapes and sketch only those plus a few basic overall contours. as an architect, i was taught in school how to draw, fortunately because now i am not so sure about a lot of design schools and the impacts of digital graphics--another story. during a workshop with Eric Weigardt, Eric looked at my preliminary sketches and suggested i draw less detail. Why? the amount of detail was affecting the way i painted, pulling me into painting shapes and not larger cluster in the composition. Reid does the opposite, a lot of detail using contour drawing for an impressionist.
i find they both work using contour drawing that can be self taught. i use less drawing now as i did earlier and enjoy how that forces my brain to think about the larger painting and not inidividual shapes.

Hope this helps, let me know, keep painting. Ron K
