NO TAG SOUP. NO KEYWORDS WITHOUT CONTEXT. NO "BEAUTIFUL, 4K, REALISTIC."
Every prompt MUST tell a story with intention, imperfection, and visual metaphor.
Violating the letter of this rule is violating the spirit of authentic visual storytelling.
Use for blog cover image creation:
Use this ESPECIALLY when:
Don't skip when:
You MUST complete each phase sequentially. Skipping phases guarantees AI-looking output.
BEFORE writing ANY prompt:
Identify the Core Message
Extract the Visual Metaphor
Gate: You cannot proceed until you have articulated the metaphor in one sentence.
Structure the layout BEFORE describing content:
Establish Perspective
Place Main Subject
Secondary Elements
Gate: Your prompt must include explicit spatial instructions.
REQUIRED imperfection keywords (choose 2-3):
| Category | Keywords |
|---|---|
| Texture | organic hand-drawn texture, visible brushstrokes, subtle paper grain |
| Lines | slightly imperfect line work, slightly uneven lines, authentic hand-crafted quality |
| Photo | analog film grain, 35mm texture, soft focus with natural lens aberrations |
| Surface | natural imperfections, lived-in feel, weathered edges |
Style reference pattern:
In the style of [specific artist/movement] meets [second influence],
with [era] sensibility.
Recommended artist references for tech blogs:
MANDATORY in every prompt:
Avoid: symmetry, perfect lighting, stock photo aesthetic, HDR look,
oversaturation, plastic textures, overly smooth surfaces,
generic tech imagery (circuits, binary code, glowing screens),
CGI render aesthetic, uniform lighting, airbrushed appearance,
AI-generated "polished" look.
Gate: If your prompt lacks an "Avoid" section, it WILL produce AI slop.
EVERY blog cover MUST include the article title as prominent text overlay.
Parse the Title
Title Placement Rules
| Placement | When to Use |
|---|---|
| Top third (default) | Standard blog covers, clean separation from visual |
| Center | When illustration has negative space in middle |
| Bottom third | When key visual element is at top |
Title text: "[MAIN TITLE]" in bold, prominent typography
positioned at the [top/center] of the image.
[If subtitle exists:] Subtitle "[SUBTITLE]" in lighter weight,
smaller size, directly below the main title.
Text styling: clean sans-serif or bold serif, high contrast
against background, with subtle drop shadow or text backdrop
for readability.
Gate: If your prompt lacks explicit title typography instructions, it WILL produce a titleless image.
Use this template structure:
Create a [type: conceptual editorial illustration/hand-drawn illustration/watercolor scene]
for a blog post about "[BLOG TITLE]".
Visual metaphor: [ONE SENTENCE describing the clever visual concept]
Composition: First, establish [horizon/perspective]. Place [main subject]
in the [position] of the frame, [doing what]. [Secondary elements] occupy
the [position], creating [visual relationship].
TITLE OVERLAY (REQUIRED):
Main title: "[MAIN TITLE]" in bold, prominent typography at the [top/center] of the image.
[If subtitle:] Subtitle: "[SUBTITLE]" in lighter weight, smaller size, directly below.
Typography: [serif/sans-serif], high contrast against background, with [subtle drop shadow/semi-transparent dark backdrop] for readability.
Title should be the LARGEST text element, immediately readable.
Style: [Style reference] with [imperfection keywords].
Limited color palette: [base color], [secondary], single accent color ([specific color]).
Shot on [lens]mm at f/[aperture], [film stock] aesthetic. [Lighting type] from [direction].
Mood: [emotional quality]—[qualifier] (e.g., "intellectually witty, slightly ironic but not cynical")
Include: [specific details that add personality]
Avoid: [full anti-AI armor list]
If you catch yourself thinking:
ALL of these mean: STOP. Return to Phase 1 and find a better visual metaphor.
| Excuse | Reality |
|---|---|
| "The topic is too technical for metaphors" | Technical topics NEED metaphors most—literal depictions bore readers |
| "Simpler prompts give better results" | Nano Banana Pro is a Thinking model—it NEEDS context to reason |
| "I'll add imperfections in post-processing" | AI bakes in the aesthetic—you cannot un-smooth plastic textures |
| "Asymmetry looks unprofessional" | Symmetry is the #1 AI tell. Professionals use intentional asymmetry |
| "The Avoid section is overkill" | Without it, the model defaults to its trained average—which is AI slop |
| "I know what I want, I don't need the template" | The template forces the thinking that produces good results |
| "Long prompts confuse the model" | Nano Banana Pro handles 1000+ tokens. Detail = precision |
| "I'll add the title in Figma/Canva later" | Title is part of the composition—AI considers text placement in layout |
| "The title will cover the nice illustration" | Good composition reserves space for title. That's the Phase 5 job |
| Phase | Key Activities | Success Criteria |
|---|---|---|
| 1. Context | Extract core message, find visual metaphor | One-sentence metaphor articulated |
| 2. Spatial | Chain-of-thought positioning | Explicit 9-grid placement in prompt |
| 3. Style | Add imperfection keywords, artist reference | 2-3 imperfection terms included |
| 4. Anti-AI | Add full Avoid section | Avoid section present with 8+ items |
| 5. Title | Parse title/subtitle, specify typography & placement | Title overlay instructions in prompt |
| 6. Assembly | Use template, verify completeness | All sections present, specific details |
From research findings:
| Constraint | Rule | Why |
|---|---|---|
| Default Resolution | 1600 x 840 px (if not specified) | Blog cover optimal ratio (1.9:1), balances quality and load time |
| Edit limit | Maximum 3 edits per conversation, then start new chat | Model gets "stuck" after 3-4 edits |
| Text in images | 3 words maximum | Success rate: 1-3 words = 75%, 4-8 = 40%, 9+ = 15% |
| Resolution tier | Use 2K (not 4K) in Gemini | Same token cost as 1K, 4K doubles cost |
| Language | English prompts ONLY | Korean prompts have limited generation support |
| Failed attempts | Count against daily quota | Even failures consume your allocation |
Resolution Defaults:
| Input | Applied Resolution |
|---|---|
| No resolution specified | 1600 x 840 px (default) |
| "wide" / "landscape" | 1600 x 840 px |
| "square" | 1200 x 1200 px |
| "portrait" / "vertical" | 840 x 1200 px |
| Custom (e.g., "1920x1080") | Use specified dimensions |
❌ Tag Soup (FAIL):
kubernetes networking diagram, cloud, containers, 4k, professional, clean
✅ Context-Rich (SUCCESS):
Create a conceptual editorial illustration for a tech blog about
"Kubernetes Networking Demystified".
Visual metaphor: A postal worker (representing kube-proxy) sorting letters
in a vast warehouse of identical shipping containers, each container
having a small glowing address label.
Composition: First, establish the horizon line at the lower third.
Place the postal worker in the right third of the frame, mid-action
sorting letters. Endless rows of containers recede into the misty
background in the left two-thirds, creating depth.
TITLE OVERLAY (REQUIRED):
Main title: "Kubernetes Networking" in bold, prominent sans-serif typography
at the top third of the image, left-aligned.
Subtitle: "Demystified" in lighter weight, smaller size, directly below.
Typography: clean sans-serif (like Helvetica Bold), white text with subtle
dark drop shadow for contrast against the warm cream background.
Title should be the LARGEST text element, immediately readable.
Style: In the style of Christoph Niemann meets vintage industrial
illustration, with 1950s instructional manual sensibility.
Visible brushstrokes, subtle paper grain, slightly uneven lines.
Limited color palette: warm cream background, charcoal grey lines,
single accent color (vermillion red on the address labels).
Shot on 35mm with analog film grain.
Mood: Intellectually playful—making the complex feel approachable
without being childish.
Include: Tiny detail of a confused letter floating between containers,
the postal worker's slightly bemused expression, coffee cup on a crate.
Avoid: symmetry, perfect lighting, stock photo aesthetic, HDR look,
oversaturation, plastic textures, literal Kubernetes logos,
generic cloud imagery, CGI render aesthetic, circuit board patterns.
Image dimensions: 1600 x 840 pixels
❌ Literal (FAIL):
slow pipeline, loading bar, frustrated developer, modern office
✅ Metaphorical (SUCCESS):
Create a whimsical editorial illustration for a tech blog about
"Why Your CI/CD Pipeline is Slow".
Visual metaphor: A Rube Goldberg machine made of conveyor belts,
where a tiny commit (represented as a paper airplane) must travel
through absurdly elaborate contraptions, while a developer watches
with a cold cup of coffee, cobwebs forming on their shoulders.
Composition: First, establish a slight Dutch angle for dynamic tension.
The Rube Goldberg machine dominates the left two-thirds, spiraling
from foreground to background. The developer sits in the lower right
corner, tiny compared to the machine, emphasizing the absurdity.
TITLE OVERLAY (REQUIRED):
Main title: "Why Your CI/CD Pipeline is Slow" in bold, prominent typography
centered at the top of the image.
Typography: bold serif (like Georgia Bold), dark charcoal text with
semi-transparent light backdrop strip for readability against the busy illustration.
Title should be the LARGEST text element, immediately readable.
Style: In the style of Saul Steinberg meets Heath Robinson's
contraption drawings. Hand-drawn quality with ink wash technique,
visible pen strokes, organic paper texture.
Muted color palette: sepia, dusty blue, single pop of alert-red
on a flashing "BUILDING..." sign.
Mood: Gently satirical—poking fun at over-engineered systems
with warmth rather than frustration.
Include: A calendar on the wall with months crossed off, a small
plant that has grown and died waiting, mouse tracks in dust.
Avoid: symmetry, perfect lighting, stock photo aesthetic,
literal CI/CD icons, Jenkins/GitHub logos, generic office backgrounds,
oversaturated colors, photorealistic rendering.
