Welcome to the ultimate guide on Stable Diffusion prompts. If you've ever felt frustrated that your generated images don't match the quality you see online, you're in the right place. This guide aims to elevate your skills to the top 10% of Stable Diffusion users. So let's get started on your journey to becoming a diffusion wizard.

Before diving into the world of prompts, it's crucial to have your settings optimized. The synergy between optimized settings and well-crafted prompts can make a world of difference in your outputs. This guide will arm you with the knowledge and techniques you need to craft prompts that produce stunning, high-quality images.

What is Stable Diffusion?

Stable Diffusion is a powerful tool that allows you to generate images based on textual prompts. Whether you're using AUTOMATIC1111's Stable Diffusion WebUI (opens in a new tab) locally or on a cloud GPU service, the interface remains the same. This guide will focus on the ReV Animated and DreamShaper models, but the principles can be applied to other models as well.

The Basics of Crafting Prompts in Stable Diffusion

Understanding the Basic Prompt Template

The foundation of any good prompt lies in understanding its basic structure. Here's a simple template to get you started:

• Subject: e.g., girl
• Attributes: e.g., looking to side, jeweled crown
• Visual Characteristics: e.g., close-up, cinematic lighting, digital painting
• Environment: e.g., in a forest
• Quality Descriptors: e.g., best quality, masterpiece

When combined, these elements form a comprehensive prompt:

Sample Prompt: girl, looking to side, jeweled crown, close-up, cinematic lighting, digital painting, vibrant colors, in a forest, best quality, masterpiece

The Power of Quality Tags

Quality tags like "masterpiece" and "best quality" can significantly enhance your prompt. These tags are especially effective with anime-oriented models. The impact of these quality tags varies depending on the model you're using, but they generally serve to elevate the quality of the generated image.

Sample Prompt with Quality Tags: ((masterpiece)), (best quality), girl looking to side, jeweled crown, close-up, cinematic lighting, vibrant colors, fantasy art, digital painting, ethereal glow, forest

The Role of Negative Prompts

Negative prompts serve to guide the AI away from generating undesirable content. They can be of two types:

1. Undesirable Content: e.g., "bad hands," "mutated"
2. Conceptual Opposite: e.g., "noodles" if you're generating "rocks"

Negative prompts are not just about what you don't want in the image; they also serve to steer the AI in a specific direction. It's like a game of tug-of-war where you're pulling the AI away from unwanted outcomes.

Sample Negative Prompt: cartoon, 3d, ((disfigured)), ((bad art)), ((deformed)), ((poorly drawn)), ((extra limbs)), ((close up)), ((b&w)), weird colors, blurry

The Importance of Prompt Order

Stable Diffusion processes your prompt in chunks, and the order in which you place your tokens can affect the final output. For instance, if you specify multiple colors, they might bleed into other elements. To avoid this, you can rearrange the tokens.

Sample Prompt: 1girl, close-up, red tie, green eyes, long black hair, white dress shirt, gold earrings

Camera, Lighting, and Photography Keywords

Understanding basic photography terms can significantly elevate your prompts. Keywords like "close-up," "medium shot," and "full body" can drastically change the output. These terms are not just jargon; they are tools that can help you fine-tune your vision.

Sample Prompt: full body, (masterpiece, top quality, best quality), 1girl, fractal art, absurdres, highres, ultra-detailed depiction, dynamic pose, floating hair

By now, you should have a solid understanding of the basics of crafting prompts in Stable Diffusion. But we're just scratching the surface. In the next section, we'll dive into advanced techniques that will truly set your images apart.

Advanced Prompting Techniques in Stable Diffusion

Weighting with Parentheses

In Stable Diffusion, parentheses are used to emphasize tokens. The default weight of a token is 1, and anything inside parentheses will be multiplied by 1.05. This multiplier stacks, allowing you to fine-tune the emphasis. For example, using eight parentheses around "jeweled crown" would give it a weight of 1.477, making it a dominant element in the generated image.

Sample Prompt with Weights: (girl:1.477), ((looking to side)), [[[jeweled crown]]]

Customization and Advanced Techniques in Stable Diffusion Prompt Guide

Square Brackets for De-emphasis

While parentheses are used for emphasis, square brackets serve the opposite purpose: they de-emphasize tokens. Anything inside square brackets will be divided by 1.05, allowing you to diminish the impact of certain elements in your prompt. For example, if you use six square brackets around "jeweled crown," its weight would be reduced to 0.746, making it less dominant in the image.

Sample Prompt with De-emphasis: girl, looking to side, [[[[[[jeweled crown]]]]]]

The Anime Niche: Crafting the Perfect Anime Prompts

Anime prompts have their own set of rules and nuances. The use of quality tags like "masterpiece" and "best quality" is often more effective in anime-oriented models. Additionally, anime prompts can benefit from specific stylistic keywords like "chibi," "manga-style," or "shoujo."

Sample Anime Prompt: ((masterpiece)), (best quality), anime girl, looking to side, chibi, vibrant colors, manga-style, ethereal glow, sakura trees

Anime-Specific Negative Prompts

Negative prompts can be particularly useful in the anime niche. For instance, if you're aiming for a classic anime look, you might use negative prompts like "3D," "realistic," or "western art style" to steer the AI away from those styles.

Sample Anime Negative Prompt: 3D, realistic, western art style, ((poorly drawn)), ((extra limbs))

Anime-Specific Quality Tags

In the realm of anime, quality tags can be even more specific. Tags like "studio-quality," "manga-grade," or "otaku-approved" can add an extra layer of finesse to your anime prompts.

Sample Anime Quality Tags: ((studio-quality)), (manga-grade), (otaku-approved)

Word Position and Chunking

The position of tokens in your prompt can affect the final output. Stable Diffusion processes prompts in chunks, and rearranging these chunks can yield different results. For example, if you're specifying multiple colors, rearranging them can prevent color bleed.

Sample Prompt: 1girl, close-up, red tie, green eyes, long black hair, white dress shirt, gold earrings

Camera and Lighting Keywords for Anime

Understanding camera and lighting terms can be especially beneficial for anime prompts. Keywords like "dynamic angle," "moody lighting," or "sunset glow" can add a cinematic touch to your anime images.

Sample Anime Prompt with Camera and Lighting: anime girl, dynamic angle, moody lighting, sunset glow, ((studio-quality))

Beyond the Basics: Adavanced Tips Stable Diffusion Prompts

In the world of Stable Diffusion, the power of prompts knows no bounds. As you continue to explore the possibilities, here are some additional insights and techniques to elevate your prompt game.

Experimenting with Abstract Concepts

While prompts are typically concrete, don't be afraid to experiment with abstract concepts. Words like "dreamy," "surreal," or "nostalgic" can lead to unique and artistic outputs. Remember, art is subjective, and these abstract prompts can result in highly creative and unexpected images.

Sample Prompt with Abstract Concept: dreamy, surreal, nostalgia, vivid colors, whimsical, ethereal glow

Mixing Styles with Negative Prompts

Negative prompts can be used creatively to mix styles. For example, if you want an image that combines elements of realism and fantasy, you can use a negative prompt to discourage purely realistic features while still allowing some aspects to shine through.

Sample Prompt with Mixed Styles: fantasy landscape, anime girl, ((realistic:0.5)), ethereal glow

Creating Narrative with Prompts

Prompts can also be used to craft a narrative or tell a story through the generated image. Think about the story you want to convey and use prompts to set the scene, describe characters, and evoke emotions.

Sample Narrative Prompt: deserted city at dusk, lone wanderer, post-apocalyptic, eerie silence, ominous shadows

Embracing Niche Keywords

Depending on your specific interests, you can use niche keywords to fine-tune your prompts. Whether you're into steampunk, cyberpunk, or any other sub-genre, incorporating niche terms can lead to highly specialized and visually striking results.

Sample Niche Prompt: cyberpunk cityscape, android detective, neon-lit streets, retro-futuristic, dystopian

Collaborative Prompts

Don't hesitate to collaborate with others to create prompts. Brainstorming with fellow users can lead to innovative and inspiring prompts that you might not have thought of on your own. Share ideas, experiment together, and discover new possibilities.

Sample Collaborative Prompt: [Collaboration with User123]: haunted forest, magical creatures, hidden realm, enchanted mist

Is There a "Correct" Way to Write Stable Diffusion Prompts?

The answer is both yes and no. Some users prefer grammatically correct sentences, while others opt for fragmented keywords. Both approaches have their merits. The key is to understand the underlying mechanics of Stable Diffusion and adapt your prompting style accordingly.

Sample Prompt: A photograph of a girl wearing a parka in a city
Sample Fragmented Prompt: photograph, 1girl, parka, city
