Brush techniques

Correct answer: D. Inconsistency in pressure, brush load or guide measurements

Explanation: The governing concept is consistency in repeated brushwork. Shape size depends on the guide measurement, hand pressure, brush angle, and the amount of paint held by the brush. If any of these gradually changes, later shapes can expand, making option D correct. Drying paint, changing paper, or water colour does not normally enlarge every repeated form in a progressive pattern. A sample shape and fixed guides improve control.

Correct answer: C. Moderately thick and controllably flowing

Explanation: The governing concept is paint consistency and brush control. Fine lettering needs a mixture that flows smoothly from the brush but is thick enough to hold a narrow line without spreading or forming blobs. A very watery mixture runs and loses edge control; a dry, grainy mixture breaks the stroke; and an excessively thick mixture drags, skips, and makes delicate curves difficult. Testing on scrap paper helps confirm the consistency.

Correct answer: A. Keep some shadow edges soft and others sharp according to form

Explanation: The governing rendering concept is edge variety in relation to form, light, and distance. A soft edge can suggest a gradual turn or diffused light, while a sharper edge can describe a stronger change or a nearer boundary. Option A is correct because controlled variation makes the object appear three-dimensional and natural. Making every edge black is harsh, removing shadows eliminates form information, and using one value removes modelling altogether.

Correct answer: A. Gently move a damp clean brush along the edge

Explanation: The governing concept is controlled edge softening, often called rewetting or feathering. A clean brush that is only slightly damp can be drawn gently along the dry boundary, allowing a small amount of pigment to transition without flooding the area. Thus option A is correct. Too much water creates blooms or patches, rubbing damages the paper surface, and black paint makes the edge harder rather than softer. Use minimal moisture and a light touch.

Correct answer: D. Reduce pressure and use slightly more paint or moisture

Explanation: Dry-brush texture requires limited moisture, but an extremely dry brush used with heavy pressure can create harsh, scratchy marks. Reducing pressure and adding a small amount of paint or moisture makes the stroke smoother while preserving some broken texture. Completely soaking the brush would turn the process into a wetter technique and remove the intended dry-brush character. More pressure and scratching worsen the surface. Therefore, option D is the controlled correction.

Correct answer: A. The brush has too little paint or is overly dry

Explanation: The governing concept of dry-brush technique is a controlled, small paint load dragged across textured paper. The brush must contain enough concentrated paint to leave broken marks; if it is almost empty or excessively dry, no pigment reaches the surface. Therefore option A is correct. Paper texture usually helps create the broken effect, while colour darkness and a pointed brush do not by themselves prevent a mark.

Correct answer: B. Apply a controlled next layer over the dry wash, using few strokes in one direction

Explanation: The governing principle for an even watercolour wash is consistent movement with minimal overworking. Let the first layer dry fully, then apply a thin, controlled glaze or second layer using a limited number of strokes in one direction. Scrubbing a dry surface can damage paper fibres and lift pigment; adding strokes in every direction increases patchiness, while glue is not a normal wash correction. Therefore, option B is correct.

Correct answer: C. A brush with little moisture and paint does not reach the recesses of the surface

Explanation: The governing concept is dry-brush application: the brush carries very little water and a small amount of relatively thick paint. When it is moved lightly across a textured surface, the bristles skim over the high points and do not deposit enough material in the recesses. This produces broken, rough marks, so option C is correct. Excess water would flow into lower areas, while cutting or complete paint rejection is not the normal mechanism.

Correct answer: D. Load the brush with slightly more thick paint

Explanation: The governing concept is adjusting the paint load while preserving the dry-brush condition. If the marks are too weak, the brush may contain too little thick paint; taking a slightly larger amount makes the broken texture more visible without turning the stroke into a wet wash. Therefore option D is correct. Soaking the brush or adding much water increases flow and removes the dry effect, while oil is unsuitable and unnecessary for this correction.

Correct answer: A. Low moisture, slightly thick paint and light surface pressure

Explanation: The governing concept of dry-brush work is controlled, broken paint deposit. The brush should contain very little moisture, paint with enough body to avoid flowing, and be applied with light pressure so the bristles touch mainly the raised parts of the surface. Option A provides this combination. Wet paint, a soaked surface, or heavy pressure produces smooth coverage, while flat filling removes the intended texture.

Correct answer: B. The brush contained too much moisture or paint

Explanation: Dry-brush texture depends on a nearly dry brush carrying only a small amount of paint. When the brush contains excessive moisture or paint, its bristles release colour continuously instead of leaving broken marks on raised areas, so a smooth line results. Option B identifies the most likely cause. A rough surface generally helps reveal broken texture, and brush size alone does not explain the loss of the effect.

Correct answer: A. Brush angle, pressure and speed

Explanation: The governing technique is brush control in lettering. Brush angle changes the contact width of the bristles, pressure changes how widely they spread, and movement speed affects how much paint is deposited along the stroke. Maintaining these three variables consistently produces more even thickness, so option A is correct. Paper, hue, palette and subject may affect appearance, but they do not directly control stroke width in the same way.

Correct answer: A. The viewer's eye is directed toward the main area

Explanation: The governing concept is edge hierarchy in composition. A sharp edge creates a strong boundary and attracts visual attention, while a soft or lost edge reduces emphasis and lets the surrounding area recede. Concentrating sharp edges around the focal point therefore guides the viewer’s eye and establishes a clear visual hierarchy. Equal emphasis, weak paint layers, and transparency do not follow from edge control, so A is correct.

Correct answer: B. Reduce pressure and turn the brush onto its edge

Explanation: The governing concept is control of contact area through pressure and brush angle. A flat brush makes a broad band when much of its face touches the surface. To finish with a thin line, the artist should gradually reduce pressure and rotate the brush onto its narrow edge, reducing contact width. Thus option B is correct. More pressure or a flat position keeps the mark broad, while stopping or adding water does not create a controlled taper.

Correct answer: A. The brush contains more moisture or paint than required

Explanation: The governing concept of dry brushing is a limited paint load and low moisture, which allows the bristles to skip across the surface and leave a broken, textured mark. If the mark becomes continuous and smooth, the brush probably contains too much water or paint; the gaps between bristles and paper are being filled. Therefore option A is correct. Paper roughness usually preserves or increases breaks, while handle length and colour lightness do not create continuity.

Correct answer: C. Remove excess surface moisture and use thicker paint

Explanation: The governing concept in wet-on-wet painting is controlled moisture and pigment concentration. If the paper is too wet, colours travel beyond their intended areas; very dilute paint makes this flow worse. Gently remove excess surface water and use a more concentrated mixture. Therefore, option C restores control, while adding water, wetting the paper further, or rubbing the brush would increase disturbance and spreading.

Correct answer: D. Allowing the edge of the previous stroke to dry

Explanation: An even wash depends on a continuous wet edge, consistent paint loading, and smooth movement. When the edge of one stroke dries before the next stroke touches it, the new paint re-wets and concentrates at that boundary, producing a dark band or back-run-like mark. Thus option D identifies the cause; the other choices describe practices that help prevent uneven bands.

Correct answer: B. Reduce pressure and lift the brush quickly at the end

Explanation: The governing principle is pressure control during a tapered brush stroke. A round brush makes a broad mark when pressed, but its contact area narrows as pressure is released. Reducing pressure and lifting promptly at the end produces the pointed leaf tip, so option B is correct. More pressure would widen the end, equal pressure would keep it blunt, and reversing the grip is irrelevant.

Correct answer: C. Use slight moisture and controlled blending

Explanation: Soft edges are produced by managing moisture, pressure, and the transition between adjacent paint areas. A filbert already creates a rounded petal mark; slight moisture followed by gentle, controlled blending softens an unnecessarily sharp boundary without destroying the form. Option C is correct. A completely dry brush or heavy pressure can make marks harsher, while a black outline emphasizes the edge instead of softening it.

Correct answer: D. Maintain even pressure and speed

Explanation: Uniform line width depends mainly on steady pressure, consistent travel speed, and a controlled brush angle. Pressing harder spreads the bristles and makes the mark thicker; moving faster or lifting slightly makes it thinner. Therefore option D is the main correction. Changing colour has no mechanical effect, wetting the paper may reduce control, and merely adding paint cannot compensate for uneven pressure and motion.

Correct answer: A. Introduce controlled variation in direction length and pressure

Explanation: Natural texture follows the principle of structured variation rather than mechanical repetition. Grass blades differ in direction, height, spacing, and force, so varying the fan-brush stroke while retaining an overall rhythm creates a believable effect. Option A is correct. Repeating one place, using one heavy patch, or pressing a stationary brush removes individual marks and makes the texture less natural.

Correct answer: B. The brush has been twisted repeatedly on the palette mixing the colours

Explanation: Double loading requires two colours to remain on separate sides of the brush so that they appear together but do not become a single muddy mixture. Repeatedly twisting or scrubbing the loaded brush on the palette physically blends the pigments before application. Thus option B identifies the mistake. Separate loading, a flat brush, and suitable consistency are compatible with the technique and do not by themselves cause muddiness.

Correct answer: C. The natural hierarchy and depth of branches will decrease

Explanation: Natural branch structure uses tapering: the trunk and major limbs are thicker, while secondary branches and twigs become progressively thinner. Equal thickness removes this hierarchy, making it difficult for the viewer to read growth, distance, and depth. Therefore option C is correct. It does not automatically make the tree transparent, erase leaves, or change the trunk into a round form.

Correct answer: D. Curve the strokes according to the fruit's form

Explanation: The governing drawing principle is that contour or form-following strokes describe the direction of a surface. On a round fruit, curved strokes that follow its bulging structure help the eye perceive curvature and volume; straight parallel marks flatten the form. Therefore option D is correct. Erasing, darkening only the outline, or adding dots does not describe the fruit's three-dimensional surface effectively.

Correct answer: A. The brush was rubbed too much

Explanation: The governing concept is gentle layering in glazing. Even when the underlayer looks dry, repeated scrubbing, heavy pressure, or too many passes can rework the surface and lift or disturb the paint beneath. Thus option A is the most likely cause. Transparency itself does not lift paint, a light underlayer is acceptable, and brush size alone does not cause this failure.
