Key principles for keeping product fidelity when crafting image ads with AI.

🚀 Where the product stays honest: your guide to AI packshots that hold up
Generative models are not perfect, and will often invent a label, soften a logo, or hallucinate product details. For anyone making real ads for real brands, that's a problem worth solving. The Pencil Product and Packshot Fidelity Playbook is our field guide to keeping the product itself consistent, accurate, and unmistakably on-brand, no matter how adventurous the scene around it might get!
💡 Why we made it
AI image models are extraordinary at mood, lighting, and environment, but they still drift on the details that matter most to marketers. This guide distils the techniques we use internally at Pencil to lock packshot fidelity into every generation.
🧠 From clean reference to finished render
The playbook walks through nine principles drawn from real production work, including:
Model and resolution: Why 4K from the start beats upscaling after the fact.
Scene first, product last: Lock the world before you drop in the hero.
Reference images: What a usable product shot looks like, and why glare will ruin you.
Re-attach, re-reference, specify: How to prevent the gradual drift that plagues long chat sessions.
Fine print: Where AI still struggles, and when to composite in post.
Multiple products: Two approaches for ranges and variants.
Describe physics, not vibes: Telling the model how the product sits in the world.
Each principle comes with working prompts and side-by-side outputs, so you can see exactly what the technique changes.
🛠️ Building a discipline
Product fidelity is a discipline. You'll learn how to stage a scene, anchor your reference, diagnose drift, and decide what belongs in the render versus what belongs in post-production.
