Gemini image models respond best when you describe scene, subject, camera, lighting, style, and negative constraints in plain language—not keyword soup. This guide gives reusable prompt skeletons for marketing, product, and editorial visuals.

Turn a rough idea into a structured image brief with Generate a prompt. If your concept starts from a reference photo, use upload and ask for a prompt that describes composition without copying identifiable people.

Anatomy of a strong Gemini image prompt

Order matters less than completeness. Include:

**Subject:** who or what, action, expression
**Environment:** location, time of day, weather
**Composition:** close-up, wide, rule of thirds, negative space for text
**Lighting:** softbox, golden hour, rim light, studio
**Style:** photographic, 3D render, flat illustration, watercolor
**Color:** palette hex words or mood (muted sage, high-contrast neon)
**Constraints:** no text, no logos, no watermarks, no extra fingers

Example skeleton: “[STYLE] of [SUBJECT] doing [ACTION] in [SETTING], [LIGHTING], [CAMERA], color palette [COLORS], background [SIMPLE/BUSY], for use as [USE CASE]. Avoid [ARTIFACTS].”

Photography style modifiers that help

**Lens:** 35mm environmental, 85mm portrait, macro 100mm
**Film:** Kodak Portra 400 warmth, Fuji cool greens
**Lighting:** Rembrandt, butterfly, split, overcast diffusion
**Grade:** teal-orange cinematic, desaturated documentary

Negative prompts (what to avoid)

State exclusions explicitly:

No watermarks, signatures, or garbled text
No distorted hands, extra limbs, melted objects
No copyrighted characters or logos
No low-resolution, JPEG artifacts, blurry faces

Iteration workflow

1. **Draft:** wide prompt, one variable change at a time 2. **Select:** pick best seed/composition 3. **Refine:** “same scene, tighter crop, warmer light, less background clutter” 4. **Inpaint-style requests:** “change only the mug color to cobalt; keep everything else”

Use cases by channel

| Channel | Prompt focus | | --- | --- | | Blog hero | Negative space, readable at 1200×630 crop | | Email | Simple subject, high contrast thumbnail | | Pitch deck | Clean icons, consistent palette | | App store | Device frame optional; avoid fake UI text |

Combining image + text workflows

1. Generate image prompt here 2. Generate accompanying post with How to Write Blog Posts with GPT-4 3. SEO alt text: “Describe image for accessibility in ≤125 characters: [IMAGE CONTEXT]”

Troubleshooting common failures

**Text gibberish in image:** Add “no typography”; add text in design tool later.

**Wrong product shape:** Describe materials, dimensions, distinguishing features; use reference upload.

**Over-stylized:** Add “photorealistic, natural imperfections, not CGI.”

**Busy background:** “Minimal environment, subject isolated, bokeh background.”

Ethics and disclosure

Label AI-generated marketing images where regulations require. Do not misrepresent product appearance; align hero shots with actual product photos when possible.
