Stable Diffusion 3.5 is a highly advanced AI art base model that can your ideas into high-quality visuals. Clear and detailed prompts are essential to achieving results that match your vision. By including key elements such as style, subject, composition, lighting, and technical details, you provide the model with precise guidance to generate the desired image. A well-structured prompt ensures control over each visual aspect and aligns the output with your creative goals.
Key Elements of an Effective Prompt
Crafting effective Stable Diffusion prompts requires addressing specific components that guide the AI in generating accurate and visually rich images. This guide focuses on the essential elements—style, subject, action, composition, lighting, and more—to help you optimize your prompts for the best results.
1. Style
Setting a clear style is foundational when crafting prompts in Stable Diffusion 3.5. The style you choose not only shapes the visual aesthetic but also dictates how the model interprets your request. Styles range from traditional art forms like oil painting and charcoal sketches to cutting-edge digital aesthetics such as cyberpunk or voxel art. Mixing multiple styles can also lead to visually striking and unique results, allowing you to experiment and refine your artistic vision.
Here are some popular styles to explore:
Traditional Art Styles
- Line art drawing
- Watercolor painting
- Oil painting
- Charcoal sketch
- Ink wash painting
Modern Art Styles
- Digital painting
- Surrealism
- Abstract art
- Expressionism
- Concept art
Photography Styles
- Black-and-white photography
- Cinematic photography
- Vintage photography
- Macro photography
- Product photography
Illustration Styles
- Comic book style
- Anime-inspired art
- Children’s book illustrations
- Retro poster art
Specialized Digital Art
- Isometric voxel art
- 3D rendering
- Cyberpunk aesthetics
- Steampunk designs
Example Prompts:
- Prompt: Expressionist painting of a bustling city street at night, lights glowing with vibrant colors reflecting off wet pavement.
- Prompt: Isometric voxel art of a gamer's room with RGB-lit computer setup, posters on the wall, a character gaming in a chair, and a cat sitting on the desk by the keyboard.
2. Subject and Action
If your image has a subject, the prompt should focus on amplifying the subject's presence first, followed by describing any actions it performs. This approach ensures that Stable Diffusion 3.5 prioritizes the subject, making it the central element of the composition. Actions and interactions can then add movement and depth to make the image more engaging.
Example Prompts:
- Prompt: Wide shot of a doctor standing in a crowded hospital hallway, facing the camera with a compassionate and resilient expression. Medical staff and patients move in the background, capturing the high-energy environment.
3. Composition and Framing
Specifying composition and framing allows for control over the image’s layout and perspective. Use framing terms like “close-up,” “wide-angle,” or “over-the-shoulder” to adjust how the model positions the subject within the scene.
- Close-Up
- Wide-Angle
- Over-the-Shoulder
- Cinematic Perspectives
Example Prompt:
- Prompt: Cinematic photography, close up, a banana laying on a table, slanted shadows wash across it, soft, diffused lighting.
4. Lighting and Color
Lighting and color play a vital role in setting the mood and atmosphere of an image. By carefully selecting lighting terms, you can control how shadows, highlights, and colors bring depth and emotional resonance to the scene. Experimenting with lighting styles, angles, and colors helps give the image a unique feel, whether you want a bright and vibrant look or a moody and dramatic one.
Here are some popular lighting and color terms for prompting:
Lighting Types
- Backlight: Light coming from behind the subject, creating a silhouette or halo effect.
- Rim lighting: A narrow band of light that outlines the subject, adding dimension and separation from the background.
- Dynamic shadows: Deep, bold shadows that give a dramatic and high-contrast look.
- Soft lighting: Diffused, gentle light with minimal shadows, often used for a natural or dreamy atmosphere.
- Hard light: Direct, intense lighting with sharp shadows for a bold, impactful look.
- Golden hour lighting: Warm, soft light typically found during sunrise or sunset.
Color Effects
- Monochrome: A single color tone throughout the image, often black and white or sepia.
- High saturation: Intensely vibrant colors that create an eye-catching and bold effect.
- Pastel colors: Soft, muted tones for a light, delicate aesthetic.
- Neon lighting: Bright, artificial lighting often seen in cyberpunk or retro-themed settings.
- Cool tones: Blues, greens, and purples for a calming or mysterious effect.
- Warm tones: Reds, oranges, and yellows for an inviting or energetic atmosphere.
Example Prompts:
- Prompt: Soft, diffused, misty light. Deep, moody shadows. A vehicle sits under a tree, rusted and abandoned, its headlights shine with a yellow glow.
- Prompt: Looking up at a stage, spotlights shining on the center, red velvet curtains hanging in thick folds on the side. A woman dressed in a black gown covered with sequins sings into a microphone, dynamic light, dynamic shadows.
5. Technical Parameters
Technical parameters involve using cinematic and compositional terminology to refine the perspective, angle, and framing of the generated image. These terms are especially helpful for creating specific perspectives and enhancing the visual complexity of the scene. By including technical terms, you can give the model precise instructions to achieve the desired look.
Popular terms for technical parameters include:
Camera Angles
- Bird’s eye view: An overhead angle that shows the scene from above, offering a wide, often dramatic perspective.
- Worm’s eye view: A low-angle shot that looks up at the subject, giving a sense of grandeur or intimidation.
- Dutch angle: A tilted frame for an off-kilter, unsettling effect, often used to create tension.
- Eye level: A natural, straightforward view that creates a neutral perspective.
Lens Types
- Fish-eye lens: A wide, curved effect that creates a spherical distortion around the edges, often for a unique or surreal look.
- Telephoto lens: Compresses distance, bringing faraway objects closer together and creating a more focused field of view.
- Macro lens: Ideal for extreme close-ups, capturing tiny details with clarity and precision.
- Wide-angle lens: Expands the field of view, useful for capturing large landscapes or open spaces.
Example Prompts:
- Prompt: Bird's eye view, drone fly-over footage: cinematic photography: action scene, looking down at a police car with flashing red lights racing down a street.
6. Text Integration
Stable Diffusion 3.5 allows for the incorporation of text directly within images, adding another layer of storytelling. When adding text, using short, relevant phrases enclosed in "double quotes" improves clarity. This feature is particularly useful when you want the image to deliver a message or include labels, signs, or captions that enhance its context.
Example Prompt:
- Prompt: A large running shoe sits on a table, its red laces dangling over its blue canvas upper and white sole. The words "Sports Are Fun" are scrawled across the image in green letters.
7. Negative Prompt
Negative prompts allow users to remove unwanted elements, colors, or textures from the generated image. By specifying what you don’t want to see, you can guide Stable Diffusion 3.5 to produce a more polished and focused result, free from distracting or irrelevant details. This technique helps fine-tune the output, ensuring the model aligns even more closely with your intended vision.
