What are some approaches for making effective brushstrokes?
Like most variables when creating
images, an artist’s vision of what constitutes an effective brushstroke is
driven by what the artist wishes to project. For example, Vincent van Gogh’s choice
of brushstroke is driven by the need to express deeply felt personal
experiences, whereas an artist like Georges Seurat’s choice, by comparison to
van Gogh, is driven by cerebral concerns rooted in theory. Mindful of this, the
idea that there may be one type of effective brushstroke that is good for all
occasions is unrealistic. Nevertheless, from a practical standpoint there are fundamental
principles underpinning the way that an artist makes meaningful brushstrokes and
the following discussion will address some of these with reference to: loading the
brush (i.e. wetting the brush with ink or paint); handling the brush (i.e. use
of the brush to apply the medium of either ink or paint to the support); and, ending
the brushstroke (i.e. the finishing touch of making a brushstroke).
Regarding ideal ways that artists can load their
brushes, I wish to propose two useful approaches: loading a brush for fluid
mediums like watercolour and ink; loading a brush for viscous mediums like oil
paint and acrylic when the paint has not been thinned with a solvent.
When working with fluid mediums, the Eastern approach for loading a brush offers artists the opportunity to create brushstrokes exhibiting variations of tone and opacity within each stroke. Essentially the process of loading a brush consists of three key stages with each stage designed to produce different tones within the brushstroke (see the illustrations below).

Essentially the process of loading a brush consists of three key stages with each stage designed to produce different tones within the brushstroke (see the illustrations below).
Step 1: immerse the brush-head in clear water.
Step 2: Immerse brush-head two-thirds of its length from the tip into a mid-tone of the colour chosen.
Step 3: Immerse the tip (or not more than the top-third) of the brush-head into the full-strength colour.

A brush loaded in this way produces
brushstrokes that are darker towards their centre and lighter at their edges.
An extension of this approach is to load the brush with multiple colours so
that each stroke can produce a multi-hued effect. This traditional approach to
loading the brush enables Oriental artists to create a tonal range within each
stroke as shown in the way that the leaves and flowers are portrayed below.

When working with viscous mediums, the Western
approach of loading a flat brush (i.e. a square-ended brush) is to ensure that a
ball of paint is positioned towards the centre of the brush-end (see illustration
below). By loading the brush in this way the resulting brushstrokes exhibit an
even spread of paint that defines the shape of each stroke laid. This is
important because if an artist were to load the brush with a random dollop of
paint (e.g. scooping up paint from the palette with the brush without
considering how the paint will spread in a stroke) the resulting brushstroke
will inevitably have an inexpressive sloppy ridge of paint on either side of the
stroke. More worrying, the shape of the brushstroke may also be lost (see
illustration further below of the typical ridges formed when the brush is not
loaded with care).

The approach of using lateral
pressure describes the angle that an artist holds the brush when making a stroke. By
angling the brush, the resultant stroke exhibits a crisp, unbroken edge on the
side of the brush on which pressure is made and a comparatively less defined,
crumbly edge on the farther side of the stroke. This change in the attribute of
the brushstroke-edge from one side to the other is most noticeable with curved
brushstrokes. The reason for this is that with curves, the lateral pressure on
the brush moulds the paint like a current of water in a river moulds the two
sides of the river-bank differently. For example, in Negasawa Rosetsu’s visually
arresting ink painting, Sparrows and
Spider (shown below), note how the variations in pressure on the sides of
each mark animates the portrayed tangled vines with the spirit of life (see detail further below).

The second approach whereby the artist angles the head of the brush is one of the fundamental principles for both painting and calligraphy. The reason for this is simple. When the tip of the brush is angled (usually at about 45 degrees to the direction that the artist plans to make a mark) the brushstroke will exhibit all the artist’s deviations of direction by the line either thinning or swelling in its thickness. For example, in the earlier post, Passion in a Line, Carl Rohrs’ angled handling of the pen is shown in Bounce (see below). Not only does the angling of the pen give flow to the word but it also captures the spirit of the word’s meaning. Compare, for instance, the projected meaning offered by Rohrs’ calligraphy to the OCR-A font developed in 1968 for optical character recognition shown further below.

With regard to fundamental
principles about how an artist should end a brushstroke there are two critical
rules: creating pictorial coherence within the matrix of brushstrokes (i.e.
ensuring that the brushstrokes are pictorially woven together) and
communicating meaning (i.e. ensuring that the tail-end of a stroke connotes the
type of passion and confidence appropriate to the expressed meaning of the
artwork as a whole).
The first of these “rules”
addresses the important issue that all components of an image should work
together to project a clear message. This means that if the artist draws
attention to each brushstroke so that all the brushstrokes are arresting to the
eye, the image may become fragmented. After all, if each mark is in visual
competition with those surrounding it the viewer will become distracted from
understanding the artwork and its broad meanings as a whole.
To ensure that the brushstrokes are
woven together, artists often overlap the tail-ends of earlier laid strokes so
that that there are no individual strokes revealing both their start and their
end (see illustration below). Of course, sometimes a viewer’s attention needs
to be focused on a specific mark and so both the start and its end are visible.
To explain this metaphorically, such a stroke will appear to float like a boat
on a sea of marks beneath it and draw attention to itself (see example of such
a stroke further below).

The second of the rules, communicating meaning, is perhaps the most important. This is because the end of a brushstroke can capture the spirit in which an artwork is executed and even the reason for a mark’s existence. In terms of how the end of the brushstroke can capture the artist’s mindset, I wish to compare the end of a mark that I see as looking like whipped cream (see illustration below) with the end of a mark that I see as looking like a lock of hair formed as a kiss-curl (see illustration further below). The first mark—“whipped cream”—suggests that the artist hesitated tentatively and lifted the brush vertically away from the canvas: arguably this would be a mindset in a state of distraction. The second mark—“kiss-curl”—suggests that the artist painted with confidence and the brush was lifted with speed in the direction that the brushstroke was laid: arguably a mindset where the artist is focused and in a flow of thought and action (i.e. “in the zone”).

Beyond the artist’s mindset that a viewer may intuitively feel or consciously rationalise through the manner of how a brushstroke is made, the chosen shape for the end of a mark is a element that the artist has total control over. For example, a square-ended mark may connote dry heat; a round-ended mark may connote humid coolness; a tapered-end on a mark may connote strong light. This list of potential meanings projected by a mark could be endless when contextualised with other marks. To illustrate how important the tail-end of a mark can be, I wish to return to Rosetsu’s Sparrows and Spider and focus on a single, but pivotal, brushstroke depicting a strand of web holding a spider in space (see detail below). Note how the line fades into the paper as it approaches the spider and consider how this treatment of the end of the line is so perfect for expressing the taut and delicate tension supporting the spider.

Thanks for your kind comments. I have tried to keep the design simple by not allowing advertisements or using too many gadgets. Nevertheless, someday soon I will start engaging in some visual cluttering when I introduce a link that lists all the blog discussions and hyperlinks so that navigation back through the old posts is not a problem. Regarding your query about when I started the blog, my first post was back in December 2009. I can still remember worrying if I had made any typos and whether the first discussions would attract any readers ...

I had deleted the following comment but my cook (Isabelle) proposed that I would be in big trouble from her if I failed to publish it. My wonderful and very wise cook’s opinion is that the comment shown below was Kalvin’s first time at posting a note and as such his interaction should be welcomed. Hopefully I will be in for a ripper of a fine dinner tonight!
ReplyDeleteMy apologies to Kavin for my lack of foresight:
“What's up i am kavin, its my first occasion to commenting anyplace, when
i read this paragraph i thought i could also make comment due to this good
article.”
I can remember my first statement that I posted on someone’s website (in fact it was in the review section for a book on Amazon.com) and it had nothing at all to do with the seller’s goods at all. I just had a look to see if it is still there and it is—how amazing!: http://www.amazon.com/The-Illustrated-Bartsch-Sixteenth-Century/dp/0898350123/ref=sr_sp-atf_title_1_1?ie=UTF8&qid=1398816628&sr=8-1&keywords=illustrated+bartsch+review
Thanks for your very welcome comment. Words of support keep me motivated ... and sometimes I really need that.
