AP 2-D Art and Design · ⁨AP אמנות ועיצוב 2-D⁩

The elements of art 艺术元素 are the visual "building blocks" every artist uses. The first is line 线条 — a moving point that the eye follows.

• A line has length and direction; it can be straight, curved, angular, or freeform.
• Lines have quality: thick or thin, smooth or rough, continuous or broken, dark or light.
• Contour 轮廓 lines trace the edges of a form; gesture 动态速写 lines capture movement quickly.
• Implied lines 隐含线 are not drawn but suggested — by a row of objects or a person's gaze.

Direction carries feeling: horizontal lines feel calm, vertical lines feel strong, and diagonal lines feel active. Artists use line to build shape, shade value (hatching), imply texture, and lead the viewer's eye.

A shape 形状 is a flat, enclosed area; a form 形体 has the illusion of three dimensions (height, width, and depth).

• Geometric 几何 shapes (circle, square, triangle) are regular and mechanical; organic 有机 shapes are free and natural.
• Positive shape 正形 is the object; negative shape 负形 is the empty space around and between objects — learning to see it makes drawing far more accurate.
• Form is created on a flat surface with value (shading), overlapping, and perspective.

Value 明度 is the lightness or darkness of a tone — the single most powerful tool for showing three-dimensional form.

• A value scale 明度阶 runs from white through greys to black.
• Light on a form has a highlight 高光, midtones 中间调, a core shadow 明暗交界线, reflected light 反光, and a cast shadow 投影.
• Chiaroscuro 明暗对照法 is the bold use of light and dark to model form. Squinting removes colour and helps you judge value.

Colour 色彩 is light reflected from a surface. It has three properties and follows the logic of the colour wheel 色轮.

• Colour's three properties: hue 色相 (its name), value (light/dark), and saturation 饱和度 (dull to vivid).
• Primary 三原色 (red, yellow, blue) mix to make secondary 间色 and tertiary colours.
• Complementary 互补色 colours sit opposite on the wheel: placed side by side they intensify each other, but mixed together they neutralise 中和 into a dull grey-brown. Analogous 邻近色 colours sit next to each other and harmonise.
• Warm 暖色 colours (red, orange, yellow) advance; cool 冷色 colours (blue, green, violet) recede. A tint adds white, a shade adds black.

Texture 肌理 is the surface quality of a work — how it feels, or how it appears to feel.

• Actual (tactile) texture 实际肌理 can be physically touched (thick paint, collage, rough paper).
• Implied (visual) texture 视觉肌理 is the illusion of a surface, made with marks, value, and pattern.
• Techniques include stippling, hatching, impasto 厚涂 (thick paint), and dry-brush. Contrasting smooth and rough areas adds interest and can direct the eye.

Space 空间 is the area within, around, and between the parts of a work, including the illusion of depth on a flat surface.

• Positive space is filled by the subject; negative space is the empty area around it.
• Depth is created with overlapping 重叠, size, placement, and detail.
• A scene organises into three depth planes: foreground 前景 (nearest), middle ground 中景, and background 背景 (farthest). The nearest plane usually carries the most detail and contrast, the farthest the least.
• Linear perspective 线性透视 uses a horizon line and vanishing point 灭点 so parallel lines converge; atmospheric perspective 空气透视 makes distant things paler, bluer, and less detailed.
• The format and cropping of the picture plane shape how the space is read.

Worked example (applying the concept). Asked to describe how line creates meaning in a portrait, a strong answer names the element, its quality, and its effect: "The artist uses thick, jagged diagonal lines in the background, and their restless, active direction makes the calm horizontal lines of the sitter's shoulders feel even more still." Naming the element and linking it to a feeling is what portfolio written evidence and analysis questions both reward.

• Name the element precisely — line, shape or form, value, colour, texture, space — in any analysis.
• Justify how form is modelled with a value scale and a single light source.
• Read the colour wheel: identify complementary versus analogous schemes and warm or cool temperature.
• Separate shape (2-D) from form (3-D) and actual from implied texture.
• Explain depth with overlap, size, linear perspective, and atmospheric perspective.

The principles of design 设计原则 are the "rules" for arranging the elements of art. The first is balance 平衡 — the visual distribution of weight so a work feels stable.

• Symmetrical (formal) balance 对称平衡 mirrors both sides of a central axis — calm and orderly.
• Asymmetrical (informal) balance 非对称平衡 uses different elements of equal visual weight 视觉重量 — dynamic and lively.
• Radial balance 辐射平衡 arranges elements around a central point.

Visual weight is affected by size, colour, value, and position: a small bright shape can balance a large dull one.

Emphasis 强调 makes one part of a work stand out as the centre of interest — the focal point 视觉焦点, where the eye is drawn first.

• Emphasis is created through contrast — of size, colour, value, isolation, or placement.
• Leading lines and the rule of thirds help place a strong focal point.
• Subordination 从属 keeps other areas quieter so the focal point leads.

Contrast 对比 is the difference between elements — it creates energy, variety, and readability.

• Contrast can be of value (light/dark), colour (complementary), shape, texture, or size.
• Strong contrast attracts attention and defines a focal point; low contrast unifies and calms.
• In design, value and size contrast create clear visual hierarchy 视觉层次.

Movement 动感 leads the viewer's eye through a work; rhythm 节奏 is the repetition that creates a visual "beat".

• Movement is the path the eye takes, guided by line, edges, colour, and placement.
• Rhythm types: regular (even), flowing (curving), progressive 渐进 (gradual change), and random.
• Repetition with variation keeps rhythm interesting rather than monotonous.

Repetition 重复 reuses an element; a pattern 图案 is the repeated element arranged in a predictable way.

• Repetition of shape, colour, or line builds unity and rhythm.
• A pattern is a repeated motif 母题 — regular (a grid or tessellation) or irregular.
• Too much repetition feels monotonous; changing scale or colour adds variety.

Proportion 比例 is the size relationship between parts; scale 尺度 is the size of an element relative to something else.

• Proportion compares the sizes of parts within a work (head to body).
• Hierarchical scale 等级比例 makes the most important element the largest.
• Exaggerated or distorted proportion can express emotion or draw attention. The golden ratio 黄金比例 is a historic guide to pleasing proportions.

Unity 统一 holds a work together as a whole; variety 变化 adds interest so it is not dull. Good design balances the two.

• Unity comes from repetition, proximity 邻近 (grouping), continuity 连续性 (aligning elements along a line or edge so they read as one group), and a limited palette.
• Variety is difference that prevents monotony. Harmony 和谐 comes from similar elements.
• The best works achieve unity with variety — order that still surprises.

Composition 构图 is how all the elements and principles are arranged within the picture plane 画面.

• The format 画幅 (portrait, landscape, square) shapes the design.
• The rule of thirds 三分法 places key elements along third-lines and their intersections.
• Cropping 裁剪 decides what is included and what is cut, changing emphasis and tension.
• A strong composition unifies the elements while creating a clear focal point — this is what the AP portfolio's 2-D skills are judged on.

Worked example (applying the concept). To explain balance in a composition: "The large dark shape on the left is balanced by three small bright shapes on the right — this is asymmetrical balance, which gives the piece visual weight on both sides while keeping it dynamic rather than static." A full answer names the principle, points to specific evidence in the work, and states the effect on the viewer.

• For every work, state which principle organises it — balance, emphasis, contrast, movement, or unity.
• Justify balance through visual weight, not just symmetry.
• Ensure one clear focal point, and name the emphasis technique that creates it.
• Aim for unity with variety — name the unifying device and the source of interest.
• Plan composition with the rule of thirds and thumbnails before committing.

Media 媒介 are the materials an artist works with. Drawing media make marks directly on a surface and are the foundation of most 2-D work.

• Dry media 干性媒介: graphite (pencil), charcoal, conté, chalk and oil pastel, coloured pencil.
• Wet media 湿性媒介: pen and ink, brush and ink, markers.
• Mark-making techniques: hatching 排线, cross-hatching 交叉排线, stippling 点画, blending, and scribbling.
• The tooth 纸纹 (texture) of the paper changes the line and value possible.

Drawing is used both to investigate ideas (studies and sketches) and to make finished works.

Painting 绘画 applies pigment held in a binder 粘合剂 to a surface, building colour, value, and texture.

• Watercolour 水彩 is transparent; gouache 水粉 is opaque and water-based; acrylic 丙烯 dries fast; oil 油画 dries slowly and blends richly.
• The support 底材 and ground (paper, canvas, board; primer or gesso 石膏底料) affect how paint behaves.
• Techniques include washes, glazing 罩染, wet-on-wet, dry-brush, and impasto.

Printmaking 版画 transfers an image from a prepared surface (the matrix 版) to paper, so many copies (an edition 版数) can be made.

• Relief 凸版 (linocut, woodcut) — ink sits on the raised surface; cut-away areas stay blank.
• Intaglio 凹版 (etching, engraving) — ink sits in lines cut below the surface.
• Planographic 平版 (lithography) — image and non-image areas are on the same level, using grease and water.
• Stencil 孔版 (screen printing) — ink is pushed through open areas of a mesh.

The matrix is reversed, so the printed image is a mirror of the plate.

Collage 拼贴 assembles found materials onto a surface; mixed media 综合媒介 combines two or more materials or processes.

• Collage glues papers, photos, fabric, or found objects into a composition.
• Mixed media layers processes — for example, drawing over paint, or print with stitching.
• These add actual texture and unexpected meaning; a found material (a ticket, a map) can carry meaning beyond its look.

Photography 摄影 makes images with light and a lens; the elements and principles apply to the frame just as in any 2-D work.

• Key controls: framing, focus 对焦, exposure 曝光 (light), depth of field 景深, and viewpoint.
• The rule of thirds, leading lines, and negative space compose a photograph.
• Editing 后期 (cropping, contrast, colour) is part of the creative process, not just correction.

Digital media 数字媒介 create and edit images on a computer or tablet, working in layers.

• Raster 位图 images are made of pixels (photo editing, digital painting); vector 矢量 images use maths paths and scale without losing quality.
• Layers 图层 let an artist build, mask, and revise without damaging earlier work.
• Digital colour uses RGB (screen, additive) or CMYK (print, subtractive); keep files high-resolution 分辨率 for the portfolio.

Graphic design 平面设计 communicates a message visually; illustration 插画 makes images that support or tell a story.

• Design combines type 字体, image, colour, and layout to reach a viewer or client.
• Visual hierarchy guides the eye to what matters first, through size, weight, and placement.
• Typography 字体排印 — typeface, size, spacing, alignment — is a core design tool.
• Design and illustration are problem-solving: the audience and message shape every choice.

Worked example (writing about process). When your written evidence must explain a material and process: "I used charcoal on toned paper because its soft, smudgeable line let me build deep shadow quickly, and I lifted highlights with an eraser to suggest form." Notice the shape — name the medium, say why you chose it, and connect it to the idea you were exploring. Listing a material with no reason earns little.

• Match the medium to the intended effect, and justify the choice.
• For printmaking, state relief versus intaglio, and remember the printed image reverses.
• Explain transparent versus opaque paint, and layers and vector versus raster in digital work.
• Treat collage and mixed media materials as meaning, not just texture.
• In graphic design, show a clear visual hierarchy serving the message.

In AP Art and Design, making begins with inquiry 探究 — asking questions that guide a sustained investigation 持续探究 over time. This is Big Idea 1.

• Inquiry is asking questions to find information and drive investigation.
• A sustained investigation is an in-depth, question-driven study of materials, processes, and ideas.
• Good questions can be simple — who, what, when, where, why, how, what if, and why not.
• Questions evolve: early questions lead to new questions as the work develops.

Artists' and designers' experiences 经历 inform why, how, and what they make.

• An experience is any event — real surroundings, imagined ideas, communication, or research.
• Reflecting on experiences sparks questions and inspires investigation.
• Ideas come from observation 观察, memory, other disciplines, and other artists' work.
• Experiences can be documented with drawings, photos, notes, or sound, becoming a resource.

Every work is built from three interacting components — materials, processes, and ideas 材料、过程与想法.

• Materials are what a work is made of; processes are how it is made; ideas are what it is about.
• The components interact: a material suggests a process; a process shapes an idea.
• Investigating all three expands the possibilities for making, and influences how viewers interpret the work.

Works are made and understood within a context 语境 — traditions, cultures, and other disciplines.

• Context is when, where, how, why, and by whom a work was made and viewed.
• Artists work within, or challenge, art and design traditions 传统 from cultures around the world.
• Comparing works reveals similarities and differences in materials, processes, and ideas.
• Acknowledging references and influences shows integrity 诚信 — never copying without credit.

Works can be evaluated 评价 by using visual evidence to compare them with specific criteria 标准 (as the AP scoring guidelines do).

• Observe carefully: identify the materials, processes, and ideas, and how they connect.
• Consider whether the components show synthesis 综合 — parts working together for one effect.
• Evaluation can be informal (as you work) or formal (a critique 评图 with peers or a teacher).
• Reflecting on evaluation improves your later thinking and making.

Documentation 记录 records information and becomes a resource for the sustained investigation.

• It takes many forms: images, notes, diagrams, material samples, and written reflection.
• A process journal 创作日志 (sketchbook) records questions, experiments, and revisions over time.
• Documenting your lines of inquiry 探究路径 shows how the investigation developed.
• Consistent documentation makes writing the portfolio's written evidence far easier.

Worked example (framing an inquiry). A weak sustained-investigation question is really just a topic: "My investigation is about the ocean." A strong one is a real question that can drive many artworks: "How can I use colour and texture to show the ocean shifting from calm to dangerous?" The question names an idea and points to the visual choices you will test — exactly what raises a portfolio's score.

• Frame the work with an open guiding question, not a closed yes/no one.
• Draw on varied sources — observation, experience, research — and cite your influences.
• Aim for synthesis: materials and processes chosen because they carry the idea.
• Evaluate through critique using the elements and principles, then plan a revision.
• Keep a process journal: record experiments and failures as evidence of inquiry.

Big Idea 2 is about making. Its heart is the Sustained Investigation 持续探究 — a body of work that explores one question or idea in depth over time.

• A sustained investigation is guided by questions or inquiry and develops as you make.
• It shows practice, experimentation, and revision — not a set of unrelated pieces.
• The 2-D portfolio's Sustained Investigation section is 15 images plus written evidence.
• A clear, focused inquiry gives the whole body of work direction and coherence 连贯性.

Making advances through three linked actions.

• Practice 练习 is repeated work to build skill and understanding.
• Experimentation 实验 tries new materials, processes, and ideas to discover possibilities.
• Revision 修改 changes a work based on reflection, feedback, or new questions.
• These are shown across the body of work, not just in one final piece. Evidence of experimentation and revision is exactly what the AP readers look for.

Strong works show synthesis 综合 — materials, processes, and ideas integrated so the whole is more than its parts.

• Synthesis means the components combine to create a unified effect.
• The chosen material should support the idea; the process should serve both.
• When components are integrated, viewers read one clear message rather than separate parts.
• Synthesis develops through investigation — trying combinations and keeping what works.

The portfolio must show 2-D skills 二维技能 — the elements and principles used to organise a flat surface.

• 2-D skills are the skilful use of line, shape, value, colour, texture, space, and the principles of design.
• Skilful work shows control of value, colour, composition, and mark-making.
• Skills are demonstrated across many works, in a range of materials and processes.
• The Selected Works 精选作品 section is where 2-D skills are judged most directly.

Craft 工艺 is the quality of making; composition is the arrangement of the work — both communicate care and intent.

• Craftsmanship 匠艺 is the skilful, controlled handling of materials and processes.
• Composition applies the principles of design to organise the picture plane.
• Craft should serve the idea — sometimes a rough or raw handling is the right choice.
• Consistent quality across the body of work signals a developed artist.

A sustained investigation shows ideas developing 发展 — growing and changing across the body of work.

• Development is visible when later works build on discoveries in earlier ones.
• New questions, materials, or processes push the investigation forward.
• Not every experiment succeeds — evidence of what did not work is still valuable.
• A body of work with clear development scores higher than a set of finished-but-static pieces.

Worked example (showing development). The Sustained Investigation is scored on evidence of thinking, not just finished pieces: "My first three works used flat colour; after seeing they felt lifeless, I experimented with layered glazes in works 4–6, then in works 7–9 I combined the best of both." Describing a change and the reason for it is how you demonstrate practice, experimentation, and revision.

• Build the sustained investigation as a connected body of work, not one-offs.
• Show practice, experimentation, and revision — a documented failure still earns credit.
• Push synthesis and clear 2-D skills, and keep craft clean to the edges.
• Let each work develop from the last, raising the next question.
• Choose materials and processes that embody the guiding question.

Big Idea 3 is about presenting your work. The AP exam is a portfolio 作品集 — not a written test. It has two sections, both submitted digitally.

• The Sustained Investigation 持续探究 section: 15 images showing inquiry, practice, experimentation, and revision, plus written evidence.
• The Selected Works 精选作品 section: 5 works that best show your 2-D skills, with written information.
• Works may be physical or digital, but all are submitted as digital images. There is no timed exam — the portfolio is built across the whole course.

The Sustained Investigation is judged on the inquiry and the practice, experimentation, and revision it shows.

• Submit 15 images — works and process documentation that show the investigation over time.
• Provide written evidence 书面材料: identify the guiding questions 引导性问题, and describe how the work shows practice, experimentation, and revision.
• Images should tell the story of the inquiry, not just show finished pieces. Detail and in-progress shots are allowed.

The Selected Works section shows your best evidence of 2-D skills 二维技能 and synthesis of materials, processes, and ideas.

• Submit 5 works (physical or digital) as high-quality images.
• For each, give the materials, processes, and ideas used, plus the size.
• These works are judged mainly on the skilful use of the elements and principles; they need not belong to the sustained investigation.

Writing communicates your inquiry, processes, and ideas to viewers who cannot ask you questions.

• Written evidence must fit within the College Board character limits 字数限制 — be concise and specific.
• State the guiding question(s) of the sustained investigation clearly.
• Describe how the work shows practice, experimentation, and revision — use evidence, not vague claims.

How work is presented affects how viewers interpret it — image quality is part of the grade.

• Photograph work with even lighting, sharp focus, true colour, and no distracting background.
• Crop to the work; avoid glare, shadows, and tilted edges (keystoning 梯形失真).
• Follow the required file formats and sizes; keep resolution 分辨率 high. Poor images can hide real skill.

Both sections are scored against published scoring guidelines 评分标准 — knowing them helps you build the portfolio.

• The Sustained Investigation is scored on inquiry and on evidence of practice, experimentation, and revision.
• Selected Works are scored on 2-D skills and the synthesis of materials, processes, and ideas.
• Readers use visual evidence in the work plus your writing to apply the criteria. Design your work with the criteria in mind — not to a formula.

Portfolios must be your own work; using others' work without permission or citation is a serious violation.

• Work based on published or photographic sources 参考来源 you did not create must move far beyond duplication and cite 注明出处 the source.
• Never present another artist's work — or an AI-generated image — as your own.
• Citing influences shows integrity 诚信, not weakness. When in doubt, work from your own photos, observation, and imagination.

Worked example (portfolio written evidence). For the Sustained Investigation you write a short statement about your inquiry and how the work developed. A strong statement links idea, materials, and change: "My inquiry asked how repetition can show the passing of time. I began with pencil grids, then moved to printmaking so I could repeat one image with small changes, revising the spacing in later prints to slow the visual rhythm." One or two sentences that connect idea → process → revision score far better than a description of the finished pictures alone.

• Know the two sections: the sustained investigation (15 images) and selected works (5 works).
• Use images for process, not only finished pieces, and name the guiding question in the writing.
• Write specifically and within the character limits — point to visible evidence.
• Photograph well: even light, true colour, avoid keystoning, and keep resolution high.
• Keep it your own work: transform any sources far beyond copying and cite them.
