In
response to questions from several artists over the past weeks, I have
been giving a lot of thought to the interesting challenges that arise
when one changes mediums. Of course there is the constant dealing with
"do I paint from light to dark, or dark to light". When one is
accustomed to using oil or pastel and then switch to watercolor, it can
be tricky to remember what comes first!
However,
I think most of us manage that very well. We save the white paper when
using watercolor rather than using white paint, and at least until you
are proficient, the "traditional " method is to paint from light to
dark. When you achieve a level of mastery with watercolor, you can start
with the darks, or the mid-tones, whatever works for you. I often add
some mid-darks and darks early in the painting as that gives me a value
to judge other values against.
I
do think that there is one area that you could consider: how you handle
the edges in your painting. We do this differently with each medium,
although the principles are the same.

In
my pastel paintings, I really like cross-hatching (over-laying) colors
and then scumbling a soft pastel lightly over the surface. In this
detail of a large pastel painting, I think you can see the results of
letting the various cross-hatched colors glitter through the soft
scumbling on the surface.
I can make the edges merge, or sharpen one when necessary. Some
artists like to blend the pastels to a smooth finish; it's all a matter
of personal preference.
When
I painted in oils, I tended to use value to join or separate shapes,
and as in all mediums, controlling the warmth or coolness of the
pigments is also an important factor. i.e. a warm shape painted against a
cool shape will create a little separation, even if they are the same
value and of course, a more distinct change if deeper or different
values.
Plein Air Painting at the Frederic Church Camps
16 x 20 Watercolor on Twinrocker hand made paper
September 20, 2014
This painting shows my method of "knitting" adjacent shapes together so that they do not look like separate, unrelated planes.
I
accomplish this by continuing some of the color from the sky to the
mountain to the foreground large shape and the water, and also by
"losing" the edge where the values are similar.

Creating
a textured underpainting with gesso, and then over painting with
transparent watercolors allowed me to capture the memory of the
snow-encrusted mountain side in January.
Can
you see how the variety of edges keep your eye moving through the
painting and the cooler colors in the shadows add a luminosity to the
warmer pigments in the sunlight?
This
is by no means a complete statement on creating effective edges with
the different mediums, or the difficulties encountered when changing
from one to another. However, I think just being aware of what we are
aiming to achieve gets us off on the right "foot". So - we have started
the conversation!
