1 What Is AI Image Generation for Marketing?
AI image generation uses models (e.g., diffusion) to create visuals from text prompts or transform source images on demand. For marketing teams, that means campaign-ready graphics, product photos, lifestyle scenes, and ad variations in minutes—not weeks.
❌ Traditional
- • Shoots, models, studios, edits
- • 1–4 weeks lead time
- • Limited variations
- • Higher per-image costs
✅ Generative AI
- • Minutes to generate
- • 10–100+ variants per prompt
- • Channel-specific sizes fast
- • Lower marginal costs

5 Step-by-Step: Your First Campaign Images
1 Prep your inputs
Use a clean, high-res product shot or reference image (≥ 2048px). Gather brand color codes and any must-have visual elements (logo, badges).
2 Choose templates & channels
Pick templates per channel (e.g., 1:1 Instagram, 4:5 product card, 16:9 banner) to ensure perfect crops and composition.
3 Prompt clearly
// Prompt recipe (product hero)
"Ultra-realistic studio photo of {{product}}, soft key light, subtle rim light,
on-brand background color {{#F0F3FF}}, center composition, room for top text,
no watermark, no text, crisp, high detail"
Tip: Add negative cues like “no text, no watermark” to avoid artifacts.
4 Generate, review, refine
Create 25–50 variants, shortlist the best, then upscale winners. Use inpainting for tiny fixes (e.g., remove scuffs, adjust reflections).

8 Best Practices & Prompt Recipes
Inputs that win
- ✅ High-res sources (≥ 2048px), sharp focus, even light

soft daylight, subtle shadow, minimal style, center composition,
Instagram-ready, no text, high detail"

on-brand palette, shallow depth of field, natural reflections,

Legal & Ethics Snapshot
Use commercially safe models, avoid third-party trademarks, and be transparent where appropriate. See Adobe on commercial safety and OpenAI usage policies.
9 Troubleshooting & QA
Faces or hands look off
- • Use face-enhance/upscale; generate at higher res
- • Try DALL·E 3 or latest Midjourney for people
- • Inpaint small defects; or composite real models
Inconsistent batch style
- • Reuse exact prompt template + seed where possible
- • Lower variability; lock brand style in BananaBatch
- • Curate top 10–20% and regenerate gaps
Slow generation
- • Draft at 1024px → upscale winners only
- • Batch overnight via API/webhooks
- • Split big jobs (200) into 3–4 smaller runs
