1. The Sign Equation | 符号公式

In Year 7 Media, the most fundamental ‘formula’ is the sign equation. A sign is anything that carries meaning. It is made up of two inseparable parts: the signifier and the signified. The signifier is the physical form we can see or hear, such as a word, an image or a sound. The signified is the mental concept or idea triggered by the signifier.

在七年级媒体课程中，最基本的 “公式” 是符号等式。符号是任何承载意义的东西。它由两个不可分割的部分组成：能指和所指。能指是我们可以看见或听见的物理形式，例如一个词语、一幅图像或一个声音。所指是由能指引发的心理概念或想法。

This leads to the core equation that underpins all media analysis:

由此得出支撑所有媒体分析的核心等式：

Sign = Signifier + Signified

For example, a red rose has a signifier (the actual rose with petals and colour) and a signified (the concept of love, romance or passion). Without both parts, communication cannot happen. Media producers use signs deliberately to encode messages, which audiences then decode.

例如，一朵红玫瑰有一个能指（带有花瓣和颜色的实际花朵）和一个所指（爱、浪漫或激情的概念）。没有这两部分，沟通就无法发生。媒体制作者有意识地使用符号来编码信息，然后由观众解码。

2. Shot Sizes Guide | 镜头景别指南

Shot sizes can be remembered as a zooming ‘formula’ that moves from extreme distance to extreme detail. Each shot size has a specific name, abbreviation and purpose in visual storytelling. Learning this sequence is like practising a musical scale: it gives you control over how you communicate spatial information.

镜头景别可以记作一个变焦 “公式”，从极远距离移动到极致细节。每种景别都有特定的名称、缩写和在视觉叙事中的用途。学习这个序列就像练习音阶：它能让你掌控如何传达空间信息。

The standard shot-size ladder can be laid out in a reference table so you can quickly identify what you see on screen:

标准的景别阶梯可以列成速查表格，这样你就能快速识别屏幕上看到的内容：

Think of the ladder as a way of measuring emotional distance from the subject. A close-up is like an invitation to share feelings, while an extreme long shot makes the audience feel like an outside observer. Mastering this formula helps you decide exactly how much information to reveal in each frame.

把这个阶梯想象成一种测量与被摄体情感距离的方式。特写就像是分享情感的邀请，而极远景则让观众感觉自己是一个外部观察者。掌握这个公式有助于你精确决定每帧画面要揭示多少信息。

3. Camera Angle Impact | 摄像机角度定理

Camera angles operate by a simple theorem: the vertical position of the camera relative to the subject creates a power relationship. This can be expressed as a direct cause-and-effect rule.

摄像机角度通过一个简单的定理运作：摄像机相对于被摄体的垂直位置会创造出权力关系。这可以表达为直接的因果规律。

High Angle → Subject looks small / weak
