Introduction to Advanced Descriptive Techniques

In Section 5, we’ll explore advanced strategies for writing and implementing alt text, focusing on crafting expressive and extended descriptions. Effective alt text goes beyond naming objects; it captures mood, emotion, movement, and context. You’ll learn techniques to create descriptions that are both engaging and informative, as well as how to provide deeper insight into complex images through extended descriptions. These skills will help make your visual content accessible and meaningful for all users.

Going Beyond the Basics of Alt Text

Alt text is more than a box to check. It is an opportunity to convey the mood, tone, and character of an image. While some visuals need only a clear, functional summary, others are designed to entertain, inspire, or evoke emotion. Expressive alt text communicates not just what is in the image but how it feels to experience it.

This approach is especially valuable for artistic, editorial, and promotional images, where atmosphere and intention are as important as content. To illustrate how expressive techniques can elevate a description, consider the following comparison using a New Yorker cartoon, where humor and character dynamics are central to the visual message:

Factual: “A cartoon of a person holding a dog on a leash. Two other people are standing nearby. The caption reads: ‘Leave me and my weird mom alone!’”

Expressive: Black-and-white cartoon titled Emotional-Outburst Animal. On a city sidewalk, a small dog in a striped sweater lunges forward on a leash, shouting at two surprised pedestrians. Its bespectacled owner stands off to the side, looking embarrassed. The dog yells, “Leave me and my weird mom alone!”

The expressive version uses language to convey action (“lunges,” “shouting”), emotion (“surprised,” “embarrassed”), and character roles (dog as assertive, owner as passive). It reads like a short narrative, with the punchline delivered naturally as part of the scene.

When to Use Expressive Descriptions

Use expressive techniques when an image:

• Conveys a feeling or aesthetic
• Is part of a campaign, editorial, or artwork
• Contains layered symbolism or stylized visuals
• Uses visual storytelling rather than conveying information
• Includes movement, humor, or other sensory elements

How to Write Expressive Descriptions

To write expressively, focus on the experience the image creates. Convey tone, movement, and style without assuming the user’s interpretation.

Essence and Vibe

Ask: What kind of energy does this image give off? Is it relaxed, bold, dreamy, structured, or chaotic?

Examples:

• “A colorful, maximalist bedroom filled with mixed patterns, layered textures, and playful artwork”
• “A quiet reading nook styled in soft neutrals and natural light”

Emotion

Use emotionally suggestive language that reflects the visual tone.

Examples:

• “Joyful and spontaneous, with confetti midair and people smiling brightly”
• “Melancholy setting with long shadows and a figure looking out the window”

Sensory

Reference touch, sound, or atmosphere when relevant. This adds dimension, especially for users who respond to sensory cues.

Examples:

• “Sherpa throw that looks soft to the touch”
  “String lights that glow softly in the background, suggesting warmth”

Color

Go beyond basic color names. Use descriptive language that ties to culture, mood, or design context.

Examples:

• “Sun-washed coral” instead of “pink-orange”
• “Deep indigo walls with brass accents” instead of “blue and gold room”

Color sets the mood. Instead of simply naming it, describe what it contributes. Is it calming, loud, nostalgic?

Motion

Use active verbs and gerunds to show movement. For GIFs or animations, reflect changes over time.

Examples:

• “A cat leaping onto a bed and curling up”
  
  
• “Balloons rising slowly into a pink sky”

Avoid static phrases like “A cat on a bed” for motion-based content. Show the progression.

Humor

Humorous images, such as memes, depend on timing and tone. Build toward the punchline as the visual does.

Example:

• “Dog staring blankly into the camera, with text above reading ‘Me joining my third Zoom of the day’”

Include on-image text when it contributes to the joke. Let the humor land in context.

Abstract

Some visuals are meant to express rather than depict. This is common in abstract art, editorial layouts, or stylized branding. Use language that suggests rather than defines.

Helpful phrases:

• “Appears to…”
• “Suggests…”
• “Styled with…”
• “Decorated in…”
• “Evokes…”

Avoid:

• Assuming the artist’s intent
• Assigning emotional meaning without clear visual cues
• Inserting personal interpretations

Example:

• Instead of: “An image symbolizing the chaos of modern life”
  Try: “Abstract composition of overlapping red and black brushstrokes that appear to radiate outward in sharp angles, evoking tension or movement”

Writing expressively is not about writing more. It is about writing with greater clarity and intention. When images rely on mood, color, motion, or humor, the alt text should reflect that purpose. Expressive descriptions help convey the sensory and emotional dimensions of visual content, enhancing accessibility and user connection.

Extended Description (Long Description) Techniques

Extended descriptions, also known as long descriptions, offer detailed text alternatives for complex images that cannot be fully captured in brief alt text. These descriptions allow users with visual impairments to understand images that carry significant information, such as charts, diagrams, artworks, or maps.

When to Use Extended Descriptions

Use extended descriptions when an image:

• Contains intricate visual data
• Serves a critical role in the surrounding content
• Offers information not repeated elsewhere in the text

How to Write Extended Descriptions

Before You Write

• React: Look closely at the image. What stands out? What needs explaining?
• Analyze: How does the image relate to the surrounding content? Does it support or expand on the topic?
• Experience: Consider the visual structure. Is there a logical way to "move through" the image?
• Purpose: Why is the image here? What does the user need to understand or retain?

Planning Your Description

Organize your content from general to specific. Use headers or subheaders when appropriate to guide the reader. Outlining first ensures you include key details without becoming repetitive or disorganized.

Writing Steps

• Introduce (Alt Text): Start with a brief summary to set expectations.
• Outline: Identify the main components and their relationships.
• Summarize: Expand on each part of the outline with clear, informative text.
• Expand: Add sensory, spatial, or contextual details that help bring the image to life.

After You Write

• Ensure the description flows naturally and reads clearly.
• Maintain consistency in tone, terminology, and structure.
• Read aloud to spot awkward phrasing or vague sections.
• Edit tightly. Eliminate redundancy and aim to reduce length by a third, if possible, without losing meaning.

Section Summary

Advanced descriptive techniques help transform alt text from a functional label into a meaningful user experience. Expressive descriptions capture tone, mood, and motion, while extended descriptions provide critical detail for complex visuals. When these methods are applied thoughtfully and grounded in the visual content itself, they enhance accessibility and invite deeper engagement for all users.
