Describes the scene or subject. Try 'A serene mountain landscape at sunset' for scenic compositions.
Specifies elements to avoid. Use 'blurry, pixelated' to enhance image clarity.
Determines the image's shape. Choose '4:3' for photos or '16:9' for widescreen imagery.

# Guide to Using Imagen 4 Effectively
Google’s Imagen 4 delivers state-of-the-art text-to-image performance, balancing fidelity, speed and integration. This guide helps you choose the right parameters for varied use cases—whether you’re crafting photorealistic renders, marketing visuals or social media assets.
## 1. Core Parameters
- **prompt** (required): Describe scene, style, mood.
- **negative_prompt** (advanced): Exclude unwanted traits (e.g., “blurry, pixelated”).
- **aspect_ratio**: Pick from 1:1, 4:3, 3:4, 9:16, 16:9.
- **seed** (advanced): Fix for reproducibility or leave blank/random for fresh variation.
## 2. Photorealistic Marketing & Print
- prompt: “A high-res product shot of a stainless steel water bottle on a marble countertop”
- negative_prompt: “blurry, low-contrast, noise”
- aspect_ratio: 16:9 (wide banners) or 4:3 (catalog pages)
- seed: 42 (consistent branding across campaigns)
Leverage Imagen 4’s output for brochures, posters and website hero images. A fixed seed ensures every generation matches your brand tone.
## 3. UI Mockups & Product Visualizations
- prompt: “Minimalist dashboard UI with pastel accents, interactive charts and icon set”
- negative_prompt: “distorted text, misaligned elements”
- aspect_ratio: 4:3 (desktop) or 3:4 (tablet)
- seed: 12345 (repeatable iterations)
Use concise, component-focused prompts. Negative prompts help eliminate distortions in text or icons, maintaining pixel-perfect fidelity.
## 4. Social Media & Story Content
- prompt: “Vibrant festival scene with neon lights and diverse crowd, cinematic style”
- negative_prompt: “oversaturated, grainy”
- aspect_ratio: 9:16 for Reels/Stories or 1:1 for feeds
- seed: (leave blank) for endless creative feeds
Real-time speed and vertical or square ratios streamline asset creation for Instagram, TikTok and Snapchat.
## 5. Abstract & Concept Art
- prompt: “Surreal floating islands enveloped in pastel clouds, dreamlike watercolor”
- negative_prompt: “pixelated, low-detail”
- aspect_ratio: 1:1 (gallery style) or 16:9 (wide canvas)
- seed: (random) to explore new compositions each time
Emphasize texture and mood words. Random seeds foster serendipitous art direction and fresh concept sketches.
---
By tuning these parameters—prompt specificity, negative filtering, aspect ratio and seed—you’ll harness Imagen 4’s full potential for any project, from high-fidelity print to dynamic digital storytelling.
