Visual and Media Rhetoric

Year 9 HEAP • Persuasion • Visual media

Images are arguments. A photograph frames a subject in a particular way, a colour palette sets a mood, and a font tells the audience what kind of message to expect. These choices can support the words or quietly contradict them.

The visual situation

Element	Question	What it can communicate
Subject	Who or what is shown, and who or what is absent?	Who matters, who is affected and who is responsible.
Framing	Is the shot close, wide, high or low?	Intimacy, scale, vulnerability or authority.
Gaze	Does the subject look at the viewer, away or down?	Connection, appeal, shame or contemplation.
Colour	What dominates, and what is muted?	Urgency, calm, warning, nostalgia or hope.
Light	Is the scene bright, shadowed or backlit?	Optimism, secrecy, threat or focus.
Type	Is the font formal, handwritten, bold or small?	Authority, intimacy, urgency or delicacy.
Layout	Where does the eye go first, second and third?	The hierarchy of the message.
Sound	What music, voice, silence or noise is used?	Emotional tone and pace.

Reading a campaign image

Use the same discipline as close reading. Start with what is literally there, then move to effect, then to purpose.

Step	Question	Sentence starter
Observe	What exactly is in the frame?	"The image shows..."
Analyse	How is it composed and lit?	"The low camera angle makes..."
Interpret	What does this suggest to this audience?	"For students, this may suggest..."
Evaluate	Does it serve the campaign's purpose?	"This supports the claim because..."

Worked example: a poster about heat

A campaign about shade on a school walkway uses a wide photograph of the exposed path at midday. The frame includes a narrow strip of shadow and several students crowded into it. The caption reads: "There is room in the shade. There is no room in the sun."

Choice	Effect	Risk
Wide shot	Shows the scale of the exposed area and the smallness of the shade.	The people in the photograph may be identifiable.
High contrast	Makes the heat visible and the shaded strip look like a refuge.	Can oversimplify the range of experiences.
Short caption	Creates a clear contrast the eye can read in two seconds.	The claim about cost and maintenance is not visible.
No logo or branding	Feels like a student observation rather than an advertisement.	The audience may not know who is responsible for the campaign.

Type and layout

Choice	Typical effect	When to avoid it
Large, bold heading	Urgency and confidence.	When the issue calls for calm, detailed explanation.
Handwritten font	Personal and informal.	When the campaign needs to look authoritative.
Lots of white space	Focus and confidence.	When the audience needs step-by-step information.
Dense text block	Detail and seriousness.	When the poster will be read while walking past.
High-contrast colours	Attention and urgency.	When the colours carry a meaning the campaign has not explained.

Accessibility is part of persuasion

Use sufficient contrast between text and background.
Do not rely on colour alone to carry meaning.
Write alternative text for images that convey information.
Caption video and provide a transcript for audio.
Use a readable font size and avoid long blocks of centred text.
Check that the message still works in greyscale and on a small screen.

An inaccessible campaign excludes part of its audience, which weakens both its ethics and its reach.

Image ethics

Question	Why it matters
Do we have permission to use this image?	Privacy and copyright are legal and ethical obligations.
Can the people in it be identified?	Consent must be informed and specific.
Does the image show someone in a vulnerable moment?	Dignity matters more than a dramatic image.
Would the person recognise themselves in our caption?	Framing can misrepresent experience.
Are we using a stock image that fakes a local scene?	False evidence damages credibility.
Have we credited the creator?	Attribution respects labour and helps the audience check sources.

Design review

Question	Your notes
What does the eye see first, and is that the main message?
Which element could be removed without losing meaning?
Does the image prove something or merely decorate?
Is the type readable at the intended distance?
Does the message work for someone who cannot see the image?
Is every person shown with consent and dignity?
