Understanding the Basics of Prompting
Think of the SD 3.5 model as your creative collaborator. The clearer and more specific you are with your prompts, the better the output will be. Here's how to structure your prompts to achieve the best results:
Key Elements to Include in Your Prompt
Style
Define the visual style of the image. Examples: "a watercolor portrait of a cat," or "a digital painting of a futuristic city."
"a watercolor portrait of a cat"Subject and Action
Identify the subject and describe its action. Example: "A knight riding a horse through a dense forest at dawn."
"A knight riding a horse through a dense forest at dawn."Composition and Framing
Specify how you want the subject framed, such as close-ups or wide-angle views.
"A close-up of a flower with droplets of water."Lighting and Color
Describe the lighting style and color palette.
"Soft golden hour lighting with warm tones."Technical Parameters
Use cinematic terms like "bird's-eye view" or "wide-angle shot" to guide perspective and framing.
"A wide-angle shot of a futuristic city at night, with glowing billboards."Text
Include text in your image with quotation marks. Keep it short.
"The Future is Now" in neon lights.Negative Prompting
Use negative prompts to exclude unwanted elements.
"No people" or "Avoid bright red colors."Examples of Effective Prompts
Fantasy Artwork
"A majestic unicorn in a lush green meadow, bathed in soft sunlight, framed with tall trees on either side. The unicorn has a shimmering white mane and is surrounded by small, glowing fireflies. The color palette is pastel with soft pink and purple hues."Realistic Photography
"A close-up shot of a black coffee cup resting on a wooden table, with steam rising. The lighting is warm, with soft sunlight coming from the left, casting gentle shadows on the surface. The background is blurred, creating a bokeh effect."Surrealism
"A floating whale in the middle of a city skyline at night, with stars in the background. The whale's body is glowing, and the buildings around it are distorted, as if they are melting. The color palette is dark, with shades of blue, purple, and silver."Line Art
"A detailed line drawing of a dragon curled around a tree. The dragon's scales are intricately drawn, and the tree's branches extend outward, twisting into a complex design. The drawing has clean, sharp lines with minimal shading."Tips for Refining Your Prompts
Be Clear and Specific
The more precise you are, the better the AI will understand your vision. For example, "a red vintage sports car parked on a cobblestone street at sunset" is clearer than just "a car."
Use Visual References
Look for reference images and match them with words in your prompt. Think of the scene like it's a photograph or painting to help with phrasing.
Experiment with Variations
Try different lighting, angles, or compositions if your first attempt doesn't give the desired result.
Use Negative Prompting
Exclude unwanted elements by using negative prompts, such as "No background" or "Avoid bright red colors" if they keep appearing in your results.
Conclusion
Mastering prompt writing is essential for getting the best results from Stable Diffusion 3.5. By clearly describing the subject, style, lighting, and composition you want, you can guide the model to produce images that align with your creative vision. The more detailed and specific you are in your prompts, the more control you have over the final result.
Experiment, refine, and have fun with the process to unlock the full potential of SD 3.5's powerful generative capabilities!
