Prompting Tips: How to Generate Better AI Images

Learn how to craft better AI image prompts with the SPLICE method, plus tips for iteration and enhancement to generate high-quality visuals.

Updated over a week ago

Introduction

Creating high-quality AI images takes patience, clear prompting, and iteration. By structuring your prompts well and testing variations, you can produce images that are both visually striking and authentic to your vision.

This article is part of our Community Series, where we share tips and workflows from Gamma’s power users.

This guide is based on the SPLICE rubric, a structured image prompting framework created by community member Dr. Deepak Bhootra. He developed SPLICE while using Gamma to illustrate a book, combining AI-generated visuals with practical storytelling techniques.

Plan Your Image Concept

Before you start generating images, take a moment to plan what you want to create.

  • Define the subject and purpose. Know what you want the image to represent: characters, products, landscapes, or conceptual visuals.

  • Determine the context or environment. Consider setting, time period, or activity to make your image more realistic and engaging.

  • Select a visual style. Decide on a style like watercolor, sketch, abstract art, or photorealistic to match your creative goal.

🔷 Note: Picking a forgiving style like watercolor or line art can help smooth over small AI imperfections.

Structure Your AI Prompts with the SPLICE Rubric

Well-structured prompts lead to better results. Use Deepak's SPLICE rubric to create clear, detailed prompts:

S – Style and medium

  • What visual style or medium should the image emulate?

  • Examples: watercolor, sketch, oil painting

  • Purpose: Sets the tone and texture

P – Perspective and composition

  • What angle, zoom level, or layout should it have?

  • Examples: close-up, wide angle, cinematic framing

  • Purpose: Directs the eye and composition

L – Lighting and atmosphere

  • What lighting and mood should the image convey?

  • Examples: soft moonlight, golden hour, foggy dusk, dramatic shadows

  • Purpose: Creates emotional tone and depth

I – Identity of the subject

  • Who/what is the subject, and what are they doing?

  • Examples: A monk meditating, a crow perched

  • Purpose: Establishes the central character or action

C – Cultural and contextual details

  • What specific details make the image authentic?

  • Examples: traditional jewelry, mosaic floor, period-specific clothing

  • Purpose: Adds richness and accuracy

E – Emotion and energy

  • What feeling should the image convey?

  • Examples: quiet peace, rapturous joy, tragic longing

  • Purpose: Guides expressions, posture, and scene tone

💎 Pro Tip: Using the SPLICE rubric ensures your images are visually rich and less likely to produce unusable results.

Generate and Iterate on Images

AI image generation is a process of experimentation.

  1. Start with a clear, simple prompt. Generate a first version to get a baseline.

  2. Evaluate the result. Look for strengths (composition, colors, lighting) and weaknesses (distortions, missing elements).

  3. Refine the prompt. Adjust style, perspective, or emotional cues to move closer to your ideal image.

  4. Expect multiple iterations. High-quality images often take dozens of attempts.

🌀 Insight: Iteration is normal. As your prompting skills improve, you’ll need fewer attempts to achieve high-quality results.

Enhance and Finalize Your Images

After generating a strong base image:

  • Use AI enhancement tools. Sharpen facial features, refine edges, or add subtle lighting adjustments.

  • Check for visual consistency. Ensure elements like limbs, accessories, and background details look natural.

  • Prioritize emotion over perfection. A slightly imperfect image that captures the right feeling is often more impactful than a technically perfect but flat image.

Takeaways

➡️ Iteration is essential. Expect trial and error to get professional-quality results.

➡️ SPLICE adds structure. Detailed prompts improve accuracy, reduce errors, and save time.

➡️ AI output improves with experience. Better prompting leads to fewer unusable images over time.

➡️ Focus on storytelling or purpose. Strong images communicate emotion or context, not just aesthetics.
