What is a
simple way of making a river look shallow or deep?
Before I begin to propose a
solution to portraying the relative depth of water—or the depth to any spatial
void for that matter—I need to address an important issue concerning the prints
examined in the following discussion. When an original drawing is copied onto a
printing plate for reproduction, as is the case with Richard Earlom’s mezzotint
of Claude Lorrain’s drawing [plate] No. 5
(shown below), invariably some of the subtleties of the original drawing are
lost in the translation from one medium into another. While this is probably unavoidable
there is also the chance that the reproductive printmaker may make changes to
“improve” the original image with slight adjustments. I mention these
possibilities as the approach to portraying depth that I now wish to propose
could be interpreted as a critique of Lorrain’s drawing when in fact the image
I am examining is really the outcome of Earlom’s interpretation of Lorrain’s
drawing.

One way to represent depth of water
is to employ a very simple illusion involving the shape of the body of water. When
representing shallow water, artists use outward bulging curves like those of a
clover leaf to depict the water’s edge (see clover shape below). When
representing deep water, they use inward arcing curves like those of a holly leaf
to depict the water’s edge (see holly shape below). This focus on the shape of
the body of water involves what perception theorists describe as a “figure and
ground” illusion. For theorists, the water is perceived as the “figure” when it
is perceived to be on top of the surrounding rocks or earth by virtue of convex
curves and as “ground” when it is perceived to be below the surrounding rocks
or earth by virtue of concave curves.

To illustrate this phenomenon I
have made a schematic drawing of a waterfall with a pool of water at its base
(see below). Compare how the perception of the water’s depth changes from shallow
water when the pool is constructed with convex curves like those of a clover
leaf as opposed to deep water when the pool is constructed with concave curves
like those of a holly leaf.

In
Earlom’s [plate] No. 5 this
perceptual play of representing the water is “figure” (i.e. shallow) and
“ground” (i.e. deep) is interesting to examine. If we look at the silhouette
edge of the rock closest to the centre of the pool (see detail below), for
instance, the water is scalloping its outline leaving the rock as a holly
shape. From my viewpoint this is an awkward arrangement as, especially at the
more distant aspects of this rock the water appears to be on top of the rock.
Going further when the upper edge of the rock is isolated from its context the
water could well be interpreted as overlapping the rock like the ocean tide
coming over a shoreline (see detail further below).

Artists can overcome such a problem
by “building” concave curves out of either straight lines or small convex sections.
Interesting the same idea of only using straight lines or convex curves is also
applicable to drawing people as our bodies are fundamentally bone, tendon and
muscle with very few concave areas. To illustrate the difference of how the
outline of the rock would appear if the curves were replaced with straight and
convex lines see the digital alterations below.

A good example of the use of a
holly-shape configuration of rocks around water can be seen in another
mezzotint by Earlom reproducing a different drawing by Lorrain, No. 43 (shown below). Here swirling
water is depicted with very few concavities but this print has one other
interesting feature with regard to water: it portrays a narrow body of water by
the darkening the tone of the water into the more distant reaches of the
stream. This is a fascinating visual device as large bodies of water, such as
lakes and broad rivers, are portrayed as becoming lighter into the distance
whereas the reverse is true for narrow bodies of water like streams and creeks.
In the digitally modified images further below the tonal arrangement on the
water has been reversed to illustrate this phenomenon.
