Brush techniques

The governing concept is directional mark-making in form modelling. Strokes that follow or describe an object’s surface can reinforce its curvature, volume, and the direction from which light appears to fall. Option C is correct because direction helps the viewer read both form and surface. Price, paper weight, and brush cleaning are unrelated to this visual effect.

The governing concept is modelling form through contour-following strokes. On a round object, curved strokes that follow its surface help the eye understand its turning volume and three-dimensional structure. Option D is correct. Fixed horizontal lines, random outward marks, or a single point do not describe the object’s continuous curvature and therefore give weaker volume cues.

The governing concept is matching a brush shape to the mark it produces. A liner brush has a narrow point and long bristles that can hold enough paint for a steady, uninterrupted stroke. Therefore option A is correct. A sponge brush makes broad textured marks, a stippling brush produces dots, and a wall brush is intended for wide coverage rather than delicate lines.

Stippling is governed by the use of separate dots to build texture, tone, or visual variation. The brush tip is lifted and touched repeatedly, producing small marks whose number and spacing control the result; therefore option B is correct. Long dragging strokes create lines, soaking the brush is not a painting stroke, and one-pass coverage does not create stippled texture.

The governing principle is that visual tone in stippling depends on dot density. When dots are placed closer together, they leave less of the paper or lower layer visible, so the area reads as darker. Thus option C is correct. Widely spaced dots create a lighter tone, erasing dots removes the mark, and water alone does not create the required density.

Scumbling-like handling is based on a broken, textured application rather than smooth full coverage. A brush carrying little paint is moved lightly in irregular or small circular motions, allowing parts of the underlying layer to remain visible; therefore option D is correct. A wet stream produces a fluid wash, a tip-only line is linear, and a stationary brush cannot distribute texture.

The governing concept is atmospheric or pictorial depth: distant objects are normally shown with reduced detail, softer edges, and less forceful marks than foreground objects. Consequently, option A is correct because smaller and less distinct strokes suggest distance. Very thick, sharp, or highly textured strokes usually bring an object forward, while using only black is neither necessary nor a general rule for distance.

The governing concept is the use of detail and edge control to communicate spatial depth. Foreground or nearby objects are usually painted with more deliberate strokes, sharper boundaries, and clearer surface information, so option B is correct. Completely blurred edges reduce clarity, a water-only layer does not define the object, and leaving out strokes cannot describe its form or texture.

The governing concept is colour contamination during brush use. Paint left in the bristles can mix with the next colour, changing its hue, lowering its clarity, or making it appear muddy. Therefore option C is correct. The colour will not always turn white, brush size is unaffected, and paper smoothness is not caused by a small amount of leftover paint. Cleaning between colours prevents this problem.

The governing concept is proper brush maintenance. Paint trapped near the ferrule can dry, harden, and force the bristles apart; this changes the point or shape of the brush and makes later strokes less controlled. Thus option D is correct. The other choices describe no meaningful maintenance benefit: a handle does not become shorter, coloured rinse water is incidental, and brush weight is not the main concern.

The governing concept is opacity, meaning that the applied paint hides most or all of the surface beneath it. A sufficiently thick, evenly spread layer gives a solid colour effect, so option B is correct. Excess water makes paint more transparent, a wet surface alone contains no pigment for coverage, and strokes without paint cannot create any coloured layer. Even application also prevents unwanted gaps and streaks.

The governing concept is rhythm, which is created through purposeful repetition. When similar brush strokes recur with controlled spacing, direction, or pressure, they establish a visual beat that links separate areas of the painting. Therefore, option C is correct: repeated controlled strokes connect the parts and make the surface feel unified. Removing colours, shortening a brush, or changing paper thickness does not create visual rhythm.

The governing idea is that brush direction should describe the movement and character of the subject. A calm water surface is usually read as a broad, level plane, so light horizontal strokes with fairly even spacing suggest stillness and reflection. Option D is correct. Fast vertical marks, dense dots, or random thick lines would introduce activity and disturb the calm appearance.

The governing concept is directional movement: marks should follow the force and path of the subject. Fast-flowing water can be suggested with quick, broken strokes that travel in the direction of the current; small gaps may also imply splashes and changing highlights. Option A is correct. Stationary dots, a flat layer, or slow circular marks do not communicate rapid flow as effectively.

The governing concept is texture imitation: the direction, length, and pressure of marks should resemble the surface being shown. A feather has fine fibres that spread outward, so light, short strokes made with the brush tip create a soft, airy effect. Option B is correct. Heavy bands and thick layers look solid, while scraping with the metal part produces a harsh texture.

The governing concept is control of paint flow during a continuous stroke. If a loaded brush moves too slowly, the bristles remain over one area longer and release more wet paint there. This can cause pooling, an uneven line, or darker patches. Option C is correct. Slow movement does not automatically erase a line, break the brush, or enlarge the paper.

The governing concept is emphasis, or creating a focal point through contrast and control. More precise, deliberate, and readable brushwork in the main area gives it greater visual importance than less detailed surroundings. Therefore, option A is correct. Equal detail weakens hierarchy, leaving the subject unpainted removes its presence, and dark background strokes may compete with rather than support the focal point.

The governing concept is systematic experimentation. A stroke sample chart records the marks produced by different brushes, angles, pressures, and directions, allowing the learner to compare results and select an appropriate effect for a painting. Option B is correct. A chart does not change colour prices, replace brush cleaning, or force every artwork to look identical; it supports informed choice and skill development.

The governing concept is brush orientation: the part of the brush touching the surface determines the mark’s width. Pressing or using the broad face of a flat brush produces a wider line, while turning it so the narrow edge contacts the surface produces a thin line. Option B is correct. Adding water changes flow, not the brush’s basic width, and the other actions are unnecessary or damaging.

The governing concept is pressure control. At the beginning, pressing the brush spreads its bristles and deposits a wider mark; gradually reducing pressure and lifting the brush narrows the contact area, producing a tapered ending. Option A is correct. Equal pressure keeps the width more constant, while reversing the grip or adding water does not directly create this thick-to-thin form.

This is the wet-on-dry principle: the dry support limits the movement of moisture, while a controlled amount of paint allows the artist to define a shape accurately. Consequently, option A is correct because it produces clear, controlled edges. Paint does not disappear, bristles do not permanently spread, and paper does not automatically become shiny.

The double-loading principle places two different colours on separate edges or sides of a flat brush. As the brush moves, both loaded colours transfer together, producing a two-colour stroke with a natural transition. Thus option B is correct. Folding paper, drying paint, or diluting only one colour cannot create this simultaneous brush effect.

Dry brushing uses a brush carrying relatively little, thick or partly removed paint. On lightly textured paper, the bristles touch the raised areas while skipping the lower spaces, revealing a broken, rough mark. Therefore, option C is correct. Glass, submerged surfaces, and oiled metal are too smooth, wet, or non-absorbent for this characteristic texture.

An even wash requires a continuous supply of paint with similar moisture and pigment concentration. Preparing enough mixture before beginning prevents interruptions, so the brush can be reloaded consistently and the colour remains uniform. Option A is correct. Changing paper, cutting bristles, or exposing the work to sunlight does not maintain brush moisture and may damage the painting.

A wash is expected to have an even distribution of pigment and water across the area. If the brush carries different amounts of paint from stroke to stroke, some sections receive more pigment and become darker while others remain lighter. Therefore option B is correct. The paper size, brush handle, and colour identity do not change automatically because paint quantity varies.
