Brush techniques

The governing concept is purposeful technique selection. A brush method should serve what must be represented: texture and form, the apparent distance of the object, the chosen medium, and the mood or visual effect. Considering these factors together gives a reasoned final decision, so option C is correct. Paint quantity, brush price or overall picture size may matter practically, but each alone is too narrow to determine the most suitable technique.

The governing concept is pressure-based modulation of brush width. With a flat brush, heavier pressure spreads more bristles against the surface and produces a broader mark; lighter pressure reduces contact and produces a thinner mark. To obtain broad–thin–broad, the artist should use heavy pressure, then light pressure, then heavy pressure. Therefore option A is correct. The reverse sequence gives thin–broad–thin, equal pressure keeps the width similar, and pressure only at the end cannot form the complete pattern.

The governing concept in wet-on-wet work is controlling moisture so pigment can flow without flooding. A damp surface permits a soft transition, but visible or glossy excess water carries paint too far and destroys the boundary. Blotting that excess while retaining an even dampness gives better control, so option B is correct. Adding water increases spreading, hard scrubbing damages the surface, and completely dry paint removes the intended wet-on-wet softness.

The governing principle of dry-brush technique is that a small, controlled amount of paint catches only the raised parts of the surface, creating broken texture. If the brush begins with too much paint, the first part of the stroke deposits a heavy, smoother layer; as the paint spreads and the load decreases, the texture changes. Therefore, option C is correct. Short bristles, light paper, or a dry surface do not best explain this gradual change.

Double loading depends on keeping two paint colours on separate sides of a flat brush so that each edge leaves a recognisable colour. The governing control is correct loading combined with a steady, deliberate stroke. Excessive twisting mixes the colours and destroys the two-tone effect, so option B is correct. Pre-mixing and using one colour remove the intended contrast, while excess water weakens control and may cause bleeding.

A continuous liner-brush line depends on several linked controls: enough paint, a workable consistency, steady movement and nearly even pressure. Too much paint cannot compensate for a hand that stops, presses unevenly or uses paint that is too thick or thin. Option D is correct because it includes the complete control system. The other choices are absolute claims that contradict normal liner-brush practice and do not explain line continuity.

A filbert has a rounded end that is useful for soft edges and controlled modelling. To show the cheek’s roundness, the artist should follow the form with overlapping strokes whose direction changes with the surface curvature; this gradually builds light, middle and shadow transitions. Option B is correct. A hard straight boundary, random splatters and a stationary vertical press cannot describe the continuous volume of a rounded cheek effectively.

The governing concept is atmospheric perspective. With increasing distance, air scatters light and reduces visible detail, edge sharpness and contrast; nearby forms usually appear clearer and stronger. If the distant mountain receives hard, detailed marks while the foreground is pale and soft, these visual cues are reversed, so the mountain may seem closer. Option D states the reason. The other choices are false generalisations or deny the role of visual contrast.

The governing concept is that visual weight is communicated through value, edge, and directional control. Firm angular strokes describe the rock’s planes, dark values add mass and depth, and selected hard edges make the form feel solid. Therefore, option A is correct. A light wash lacks weight, completely soft edges weaken structure, and dots alone suggest texture without convincing volume.

The governing concept is visual hierarchy: the focal figure should receive stronger emphasis than supporting areas. Excessive background dabbing creates competing texture and contrast, so reducing both quiets the background and restores attention to the figure. Option B is correct. Erasing the subject removes the focus, adding dots increases competition, and making every area identical destroys hierarchy and variety.

The governing concept is the balance between unity and variety. Repeated directional strokes can unify a painting, but if every stroke follows one direction, they may ignore the planes, contours, and movement of individual forms. Thus option C is correct: structural and kinetic differences become less clear. Transparency and paper damage are not automatic results, while beauty is not guaranteed.

The governing concept is controlled edge softening: moisture should soften the boundary without carrying unwanted pigment into clean areas. Washing the brush removes collected colour, and blotting leaves it damp rather than dripping, so option D is correct. Continuing with a dirty brush causes muddy transfer; extra pressure or dry paint cannot provide clean moisture control and may damage the passage.

The governing concept is transparent layering: a glaze modifies the perceived colour while allowing the lower drawing, modelling, or texture to remain visible. A thin warm transparent layer applied with light, controlled strokes therefore makes option B correct. Thick opaque paint covers detail, scratching damages the lower layer, and wet mixing blends or disturbs it instead of preserving it.

The governing concept of scumbling is a broken, irregular deposit that lets parts of the underlying surface remain visible. Excessive pressure pushes pigment into more surface gaps and makes the application denser, so the broken effect decreases and a more solid layer may form. Therefore option D is correct. Light texture and greater visibility of the lower layer result from lighter handling, not heavy pressure, and pressure does not instantly dry paint.

The governing concept is clean lifting: the brush must remove pigment and then be cleaned or blotted before the next touch. If it is not wiped, the pigment held in its bristles can be transferred back to the paper, producing unwanted spots or muddy marks. Therefore option A is correct. The surface will not dry automatically, colour does not always turn white, and an unwiped brush becomes dirtier rather than cleaner.

The governing concept is tonal balance in layered negative painting. Each added dark surrounding area increases contrast and visual weight; if the paint is too dark and the remaining unpainted spaces become too small, the composition loses openness and appears heavy. Leaving more white would generally preserve lightness, while brush cleanliness and paper size do not directly create this tonal problem. Hence option B identifies the main cause.

The governing concept is a controlled comparison, similar to a simple experiment. Keep the brush, paper, and general paint conditions constant, then change only one factor—such as pressure, moisture, direction, or speed. The resulting difference can then reasonably be linked to that factor. Changing everything at once creates confounding variables, while random or selective records cannot show reliable patterns. Hence option C is the best method.

The governing concept is a lost or softened edge. When an object must merge into its background, selectively reducing the contrast and definition at that boundary makes the transition appear gradual. A lightly damp brush can join the edge colour with the surrounding area without disturbing the whole painting, so option D is correct. A dark outline or thick opaque paint would sharpen the boundary, while a fully dry brush would not blend it effectively.

The governing concept is modelling through coordinated brushwork. A light colour may suggest brightness, but the direction of strokes, gradual changes in value, and the treatment of edges explain the turning of a form and the direction of illumination. Therefore option B is correct. Light is not shown by using only pale paint; black alone or rejecting the brush would also fail to describe form.

The governing concept is tonal modelling of a curved form. A rounded vessel normally turns gradually from light through middle values toward shadow. If the brushwork changes suddenly, the eye reads the boundary as a plane change or cut rather than a smooth curve, so the vessel may look flat or angular. Option C is correct; the other choices do not follow from an abrupt tonal transition.

The governing concept is purposeful technical control joined with creative judgment. A skilled painter adjusts pressure, moisture, speed, and brush type to obtain the required edge, texture, value, or expression. Thus option B is the best sign of mastery. Repeating one stroke, buying costly tools, or working quickly may occur without understanding or control, so those choices do not prove mastery.

The governing distinction is the way the new paint covers the underlying layer. Scumbling uses a relatively dry, broken or semi-opaque application so parts of the lower surface remain visible. Glazing uses a thin, transparent layer that changes the colour beneath without hiding it completely. Thus option C is correct; the other options confuse the materials or wrongly claim the techniques are identical.

Scumbling depends on a light, broken application that leaves small gaps through which the lower layer can be seen. When the brush carries too much paint, those gaps become filled and the irregular texture is replaced by a more continuous, opaque coating. Therefore option D is correct. The other choices do not describe what excessive paint does to scumbling or to the brush.

Both methods control the amount of paint, but their visible results depend on movement and purpose. Dry brush commonly produces broken, directional or linear marks because a nearly dry brush catches the surface texture. Scumbling generally creates a more irregular, broken veil over an underlying layer. Hence option A is correct; colour name, handle length and paper size are not the main distinctions.

The governing principle of stippling is that tone is created by the density of repeated dots. If dot size remains constant, placing dots closer together produces a darker visual value because more marks occupy the same area; increasing the spacing produces a lighter value. Therefore option B is correct. The other choices alter tools or marks rather than controlling tone systematically.
