1. The Shot Size Formula | 景别公式
Shot size determines how much of a subject or scene is visible and shapes the audience's emotional distance. The basic scale can be remembered as a visual ladder from extreme long shot to extreme close-up. Each step carries a distinct narrative purpose: establish context, show action, reveal emotion, or amplify detail.
景别决定了画面中主体或场景可见的范围，也塑造了观众的情感距离。基础景别阶梯从极远景到极特写，每一步都有独特的叙事功能：交代背景、展示动作、揭示情绪或放大细节。
- ELS (Extreme Long Shot) – Subject is tiny; setting dominates. Used for spectacle and isolation.
- ELS (极远景) – 主体极小，环境占主导。用于呈现奇观与孤立感。
- LS (Long Shot) – Full figure visible; establishes body language and setting.
- LS (远景) – 全身可见；确立身体语言与场景。
- MLS (Medium Long Shot) – Cut off at knees; balances figure and environment.
- MLS (中远景) – 膝部截止；平衡人物与环境。
- MS (Medium Shot) – Waist up; natural for conversation, gesture.
- MS (中景) – 腰部以上；适用于对话、手势。
- MCU (Medium Close-Up) – Chest up; begins to emphasise facial expression.
- MCU (中近景) – 胸部以上；开始强调面部表情。
- CU (Close-Up) – Face fills frame; intense emotion, intimacy.
- CU (特写) – 面部充满画框；强烈情绪，亲密感。
- ECU (Extreme Close-Up) – Eyes, lips, or an object detail; creates tension, symbolism.
- ECU (极特写) – 眼睛、嘴唇或物件细节；制造紧张与象征意义。
tance Formula: The closer the shot, the greater the psychological closeness and intensity.
景别 → 情感距离公式：画面越近，心理亲近度与紧张度越强。
2. Camera Angle & Power Theorem | 摄影角度与权力定理
Camera angles are not neutral; they establish power relationships between the viewer and the subject. The angle from which we look influences whether we admire, fear, dominate, or feel equal to a character. Remember this visual grammar as a triangle of high, low, and eye-level positions.
摄影角度并非中立，它建立了观众与主体之间的权力关系。我们观看的角度会影响我们是崇拜、恐惧、支配还是与角色平起平坐。将这套视觉语法记成一个由俯角、仰角和水平视角构成的三角关系。
- High Angle – Camera looks down. Subject appears small, vulnerable, or weak. The audience has power.
- 俯角 – 摄影机向下看。主体显得渺小、脆弱或弱势。观众拥有权力。
- Low Angle – Camera looks up. Subject appears dominant, heroic, or threatening. The subject has power.
- 仰角 – 摄影机向上看。主体显得有支配力、英雄气概或具威胁性。主体拥有权力。
- Eye Level – Camera at subject's eye line. Equality and neutrality; the audience feels part of the scene.
- 平视角度 – 摄影机与主体视线齐平。平等与中立；观众感觉置身其中。
- Canted / Dutch Angle – Horizon is tilted. Creates disorientation, tension, or psychological unease.
- 倾斜角度 – 地平线歪斜。制造迷失方向、紧张或心理不安感。
Angle + Height = Power Index. High angle subtracts power; low angle adds it.
角度 + 高度 = 权力指数。俯角削弱权力；仰角增强权力。
3. Camera Movement Modifier | 镜头运动修饰公式
Movement adds kinetic energy and directs the viewer's eye, functioning as a modifier on the base shot. Different moves carry specific narrative functions: to reveal, to follow, to distance, or to explore. Combine these with your shot size and angle to decode dynamic meaning.
运动为画面增添动能并引导观众的视线，充当景别和角度的修饰项。不同的运动方式具有特定的叙事功能：揭示、跟随、疏远或探索。把它们与景别、角度组合，即可解读动态含义。
- Pan – Horizontal rotation from a fixed point. Scans a wide scene, follows lateral action.
- 摇摄 – 从固定点水平旋转。扫描广阔场景，跟随横向动作。
- Tilt – Vertical rotation. Reveals height, size, or power; a tilt-up can make a building or character seem imposing.
- 俯仰 – 垂直旋转。揭示高度、规模或权力；上仰能令建筑或角色显得巍然。
- Zoom – Lens changes focal length. Zoom in isolates detail or heightens emotion; zoom out reveals context or insignificance.
- 变焦 – 镜头改变焦距。推近隔离细节或强化情绪；拉远揭示环境或渺小感。
- Tracking / Dolly – Camera physically moves. Tracks forward to immerse, backward to withdraw, sideways to parallel action.
- 移动跟拍 – 摄影机实际移动。前推带来沉浸感，后拉制造疏离感，横移平行跟随动作。
- Handheld – Unsteady, shaky. Suggests documentary realism, urgency, or chaos.
- 手持摄影 – 不平稳、晃动。暗示纪录片写实感、紧迫或混乱。
Movement Type × Speed × Duration = Kinetic Narrative Intensity.
运动类型 × 速度 × 持续时间 = 动态叙事强度。
4. Colour & Lighting Emotional Formula | 色彩与灯光情绪公式
Colour and lighting are not decoration; they are symbolic shortcuts that communicate mood, genre, and character instantly. Learn to read the temperature (warm/cool) of a scene and the lighting ratio (high-key/low-key) to identify the intended emotional response.
色彩与灯光绝非装饰，它们是能瞬间传递情绪、类型与角色信息的象征性捷径。学会读取场景的色温（暖/冷）以及光比（高调/低调），就能辨认出创作者意图引发的情感反应。
- Warm colours (red, orange, yellow) – Energy, passion, danger, warmth, aggression.
- 暖色（红、橙、黄） – 能量、激情、危险、温暖、侵略性。
- Cool colours (blue, green, purple) – Calm, sadness, isolation, technology, mystery.
- 冷色（蓝、绿、紫） – 冷静、悲伤、孤独、科技、神秘。
- High-Key Lighting – Bright, even illumination; few shadows. Used for comedies, sitcoms, pop videos; suggests openness, safety.
- 高调光 – 明亮、均匀的照明，阴影少。用于喜剧、情景剧、流行音乐视频；暗示开放、安全。
- Low-Key Lighting – Strong contrast, deep shadows. Used for film noir, horror, thriller; suggests fear, secrecy, moral ambiguity.
- 低调光 – 强对比，浓重阴影。用于黑色电影、恐怖片、惊悚片；暗示恐惧、隐秘、道德模糊。
- Backlighting – Light from behind the subject. Creates silhouettes, halo effects; can convey spirituality or mystery.
- 背光 – 主体背后的光源。制造剪影、光环效果；可表达灵性或神秘。
Colour Temperature + Lighting Ratio = Emotional Atmosphere Index.
色温 + 光比 = 情绪氛围指数。
5. Sound Layering Formula | 声音分层公式
Sound in media is constructed in layers, each serving a function: to create realism, to drive narrative, or to manipulate emotion. Always break down a media text's sound into two families – diegetic and non-diegetic – and then analyse each layer separately.
媒体中的声音是分层构建的，每一层都有其功能：营造真实感、推动叙事或操纵情绪。分析任何媒体文本时，请始终将声音分解为两大族群——剧情声与非剧情声——然后分别解读每一层。
- Diegetic Sound – Exists within the story world: dialogue, footsteps, car horns, radio music the characters can hear.
- 剧情声 – 存在于故事世界内部：对话、脚步声、汽车喇叭、角色能听见的广播音乐。
- Non-Diegetic Sound – Added for the audience only: voice-over narration, soundtrack score, added sound effects the characters cannot hear.
- 非剧情声 – 仅为观众添加：画外音叙述、配乐、角色听不见的音效。
- Dialogue – Reveals character, advances plot, establishes relationships.
- 对白 – 揭示人物性格、推动情节、建立人物关系。
- Sound Effects (SFX) – Create realism, heighten action, provide auditory cues for off-screen events.
- 音效 – 营造真实感、强化动作、为画外事件提供听觉提示。
- Music / Score – Sets tone, signals genre, manipulates emotional pace, and creates unity.
- 音乐/配乐 – 定调、示意类型、调控情绪节奏并创造统一感。
- Silence – Absence of sound can be just as powerful, creating tension, emptiness, or reflection.
- 静默 – 声音的缺席同样有力，制造紧张、空虚或反思。
Total Audio Impact = Diegetic Layers + Non-Diegetic Layers + Strategic Silence.
整体声音冲击力 = 剧情声层 + 非剧情声层 + 策略性静默。
6. Todorov's Narrative Equilibrium Theorem | 托多罗夫叙事平衡定理
Tzvetan Todorov suggested that most stories begin with a state of balance, which is then disrupted, leading to a journey and eventual restoration – often changed. This five-stage theorem gives you a skeleton for any narrative from a fairy tale to a news report.
茨维坦·托多罗夫认为，大多数故事开始于一种平衡状态，随后平衡被打破，引发一段旅程并最终恢复——通常已发生变化。这一五阶段定理为从童话到新闻报道的任何叙事提供了骨架。
rrative Arc = Equilibrium → Disruption → Recognition → Attempt to Repair → New Equilibrium
叙事弧线 = 平衡 → 破坏 → 意识到破坏 → 尝试修复 → 新平衡
- Stage 1: Equilibrium – The world is stable, characters are in their normal state. Everything is as it should be.
- 第一阶段：平衡 – 世界稳定，角色处于常态。一切如常。
- Stage 2: Disruption – An event or antagonist disturbs the equilibrium. Peace is shattered.
- 第二阶段：破坏 – 某个事件或反派打破了平衡。平静不再。
- Stage 3: Recognition – Characters realise the disruption has occurred. The quest or problem is acknowledged.
- 第三阶段：意识到破坏 – 角色认识到平衡已被打破。使命或问题得到确认。
- Stage 4: Attempt to Repair – The hero takes action to solve the problem. This is the longest section with challenges and battles.
- 第四阶段：尝试修复 – 英雄采取行动解决问题。这是篇幅最长、充满挑战与战斗的部分。
- Stage 5: New Equilibrium – Harmony is restored, but the world is changed. Characters have grown.
- 第五阶段：新平衡 – 和谐恢复，但世界已改变。角色获得了成长。
This applies not only to films but also to the three-act structure of a video game, an advertisement's problem-solution format, or the setup of a magazine article.
这不仅适用于电影，也适用于电子游戏的三幕结构、广告的“问题-解决方案”模式，或杂志文章的谋篇布局。
7. Propp's Character Function Formula | 普罗普角色功能公式
Vladimir Propp analysed Russian folk tales and identified seven recurring character types defined by their narrative function, not their personality. Treat this as a casting formula: every good media text populates its story world with these archetypes, sometimes combining them in one character.
弗拉基米尔·普罗普分析了俄罗斯民间故事，归纳出七种反复出现的角色类型，它们由叙事功能而非性格定义。把此作为选角公式：任何优秀的媒体文本都会在其故事世界中放置这些原型，有时会将多个原型合并于一个角色身上。
- The Hero – Leads the quest, restores equilibrium. Often ordinary at first, then proves exceptional.
- 英雄 – 引领使命，恢复平衡。初时常平凡，后证实不凡。
- The Villain – Opposes the hero, creates disruption. Embodies evil or greed.
- 反派 – 与英雄对立，制造破坏。代表邪恶或贪婪。
- The Dispatcher – Sends the hero on the mission. May be a mentor, boss, or a letter.
- 派遣者 – 指派英雄踏上征程。可能是导师、上司或一封信件。
- The Donor / Helper – Provides a magical object or vital advice. Tests the hero first.
- 赠予者/帮手 – 提供魔法器物或关键建议。会先考验英雄。
- The Princess (or Prize) – What the hero seeks; often a person, treasure, or status. May need rescuing or may be an equal reward.
- 公主（或奖赏） – 英雄追寻的目标；常为人、珍宝或身份。可能需要拯救，也可能为同等回报。
- The Princess's Father – Rewards the hero, often by giving the princess in marriage or granting recognition.
- 公主之父 – 奖励英雄，常以将公主相许或给予认可的方式。
- The False Hero – Claims credit falsely; eventually exposed. Creates a red-herring subplot.
- 伪英雄 – 冒领功劳；最终被揭穿。制造转移注意力的次要情节。
Story Power = Sum of Character Functions × Conflict Intensity.
故事能量 = 角色功能总和 × 冲突强度。
8. Uses and Gratifications Audience Formula | 使用与满足受众公式
Blumler and Katz proposed that audiences are active, not passive. They choose media to satisfy specific needs. This formula helps you predict why a target audience would engage with a particular media product, from a true-crime podcast to a social media challenge.
布鲁姆勒与卡茨提出，受众是主动而非被动的。他们选择媒体来满足特定需求。这个公式能帮你预判目标受众为何会接触某个媒体产品，从真实犯罪播客到社交媒体挑战。
rsonal Identity Need + Integration & Social Interaction Need + Entertainment Need) - Barriers to Access
媒体选择 = （信息需求 + 个人身份需求 + 整合与社交互动需求 + 娱乐需求） - 获取障碍
- Information & Surveillance – Seeking news, learning, satisfying curiosity about the world.
- 信息与监视 – 寻求新闻、学习新知、满足对世界的好奇。
- Personal Identity – Reinforcing personal values, finding models of behaviour, identifying with others.
- 个人身份 – 强化个人价值观、寻找行为榜样、与他人产生认同。
- Integration & Social Interaction – Gaining a sense of belonging, conversing with others about media, substituting real-life companionship.
- 整合与社交互动 – 获得归属感、与他人谈论媒体话题、替代现实陪伴。
- Entertainment & Escapism – Relaxation, emotional release, filling time, pleasure.
- 娱乐与逃避 – 放松、情绪宣泄、打发时间、获得愉悦。
When analysing a text, ask: Which of these needs does it serve, and for whom? A fitness app, for example, serves information (tracking), identity (being a healthy person), and integration (sharing results).
分析文本时，问一问：它满足了上述哪种需求？又为谁而满足？比如健身 APP 同时满足信息（追踪）、身份（成为健康的人）和整合（分享成果）需求。
9. Representation Equation: Stereotype vs. Countertype | 表征等式：刻板印象与反刻板印象
Representation is the way media re-presents people, places, and ideas. It is never a neutral reflection of reality but a construction that can reinforce or challenge social categories. Use this equation to measure whether a representation leans towards a stereotype or a countertype.
表征是媒体对人物、地点和观念进行再呈现的方式。它从来不是对现实的中立反映，而是一种能强化或挑战社会类别的构建。用这个等式来衡量一个表征是趋向刻板印象还是反刻板印象。
Representation = Selection + Omission + Mediation → Effects on Audience Perception
表征 = 选择 + 省略 + 中介化 → 对受众认知的影响
- Stereotype – A simplified, exaggerated, often negative generalisation about a group. Reduces a diverse group to a few traits. Repeated exposure normalises these traits.
- 刻板印象 – 对某一群体简化、夸大、常带负面色彩的概括。将多元群体缩减为少数几个特征。反复接触会将这些特征常态化。
- Countertype – A positive or unexpected representation that challenges the dominant stereotype. Can be equally simplified but deliberately subverts expectation to create new norms.
- 反刻板印象 – 挑战主流刻板印象的积极或意外表征。可能同样被简化，但有意颠覆预期以建立新规范。
- Archetype – The original pattern or model from which copies are made; more universal and neutral. For example, 'the mentor' is an archetype, not a stereotype.
- 原型 – 被反复复制的原始模式或模型；更具普遍性和中立性。例如“导师”是原型而非刻板印象。
- Tokenism – Including one underrepresented person to give the appearance of diversity without true equality.
- 象征式包容 – 仅纳入一位弱势群体成员以制造多元假象，实则缺乏真正平等。
Always ask: Who made this? For what purpose? Who benefits from this representation?
永远记得问：谁制作的？出于何种目的？这一表征让谁获益？
10. Semiotics Core Formula: Sign = Signifier + Signified | 符号学核心公式：符号 = 能指 + 所指
Ferdinand de Saussure's model teaches that every sign in media is made of two inseparable parts: the physical form (signifier) and the mental concept (signified). Together they create meaning that depends on cultural codes. This formula underpins how logos, colours, and even sounds carry connotative meaning.
索绪尔的模型告诉我们，媒体中每一个符号都由两个不可分割的部分构成：物质形式（能指）与心理概念（所指）。二者结合产生依赖于文化符码的意义。这个公式揭示了标志、色彩甚至声音如何承载内涵义。
Sign = Signifier (word, image, sound) + Signified (concept it represents)
符号 = 能指（词语、图像、声音） + 所指（所代表的概念）
- Denotation – The literal, dictionary meaning. A red rose denotes a kind of flower.
- 外延 – 字面、字典意义。一朵红玫瑰花外延指一种花。
- Connotation – The cultural, emotional associations. The same rose connotes romance, passion, or socialism, depending on context.
- 内涵 – 文化、情感联想。同一朵玫瑰根据语境可内涵浪漫、激情或社会主义。
- Myth (Barthes) – ion becomes so dominant it is seen as natural or universal truth. E.g., thinness = health.
- 神话（巴特） – 当某个内涵成为主导并被视为自然或普世真理时。例如瘦 = 健康。
Apply this to any text: take a brand logo (signifier) and deconstruct what values (signified + myth) it sells.
将这一公式应用于任何文本：取一品牌标志（能指），解构它在贩卖何种价值观（所指 + 神话）。
11. Media Industry Funding & Regulation Formula | 媒体产业资金与监管公式
Understanding how a media product is funded and regulated reveals its purpose and constraints. Whether public service or commercial, the economic model shapes content. This formula helps you compare institutions like the BBC, Netflix, or a local newspaper.
理解一个媒体产品的资金来源与监管方式，就能揭示其目的与限制。无论是公共服务还是商业性质，经济模式都在塑造内容。这个公式帮你比较 BBC、Netflix 或本地报纸等不同机构。
Content Bias ≈ Funding Source + Regulatory Obligations - Independence Buffer
内容偏向 ≈ 资金来源 + 监管义务 - 独立性缓冲
- Public Service Broadcaster (e.g., BBC) – Funded by licence fee; must inform, educate, entertain; regulated by Ofcom for impartiality, accuracy.
- 公共服务广播（如 BBC） – 靠电视牌照费资助；必须提供信息、教育、娱乐；由 Ofcom 监管其公正性与准确性。
- Commercial Broadcaster (e.g., ITV, Channel 4) – Funded by advertising or sponsorship; content attracts audiences for advertisers; lighter touch regulation.
- 商业广播（如 ITV、第四频道） – 靠广告或赞助资助；内容为广告商吸引观众；监管较轻。
- Subscription Video on Demand (e.g., Netflix, Disney+) – Funded by subscriptions; global platform with algorithm-driven recommendations; less direct regulation, driven by viewer retention.
- 订阅制视频点播（如 Netflix、Disney+） – 由订阅费资助；全球化平台，算法推荐驱动；受较少直接监管，更看重观众留存。
- Print & Online Media – Funded by sales, ads, subscriptions; regulated by IPSO (press) or self-regulation; editorial line often reflects owner's interests.
- 印刷与网络媒体 – 靠发行、广告、订阅资助；由 IPSO（报业）或自行监管；编辑方针常反映所有者利益。
Always trace the money flow to understand why certain stories are covered and others are ignored.
始终追踪资金流，以理解为何某些故事被报道而另一些被忽略。
12. Media Ethics & Legal Bounds Quick Theorem | 媒体伦理与法律边界速记定理
Media creators must operate within legal and ethical boundaries. These rules protect individuals and society but can also be creatively negotiated. Remember them as a set of non-negotiable constraints that shape acceptable content.
媒体创作者必须在法律与伦理边界之内运作。这些规则保护个人与社会，但也可以被创造性地协商。把它们记成一组不可协商的约束条件，它们塑造了可被接受的内容。
- Defamation (Libel/Slander) – Publishing false statements that damage reputation. Defence: truth, honest opinion, or public interest.
- 诽谤（文字/口头） – 发布损害他人名誉的不实陈述。抗辩理由：真实、诚实的意见、公共利益。
- Privacy – Respecting individuals' private lives unless overridden by public interest. Intrusion must be justified.
- 隐私 – 尊重个人私生活，除非被公共利益凌驾。侵扰必须有正当理由。
- Copyright & Intellectual Property – Protects creators' original work. Fair dealing allows limited use for criticism, review, or education.
- 版权与知识产权 – 保护创作者的原创作品。公平交易允许为批评、评论或教育目的进行有限使用。
- Obscenity & Harm – Material must not deprave or corrupt audiences. Additional protections for children via watershed and age ratings.
- 淫秽与伤害 – 内容不得腐化观众。通过分水岭时段和年龄分级给予儿童额外保护。
- Representation & Diversity Codes – OFCOM and IPSO require fair portrayal, avoiding harmful stereotypes and ensuring a range of voices.
- 表征与多样性准则 – Ofcom 和 IPSO 要求公正呈现，避免有害刻板印象，确保多元声音。
Acceptable Content = Story Idea - Legal Risk + Ethical Justification.
可接受的内容 = 故事构想 - 法律风险 + 伦理正当性。
