Stable Diffusion Prompt Symbols

Writing a good AI prompt is a skill that takes practice to master. As you experiment with different AI tools like DALL-E, Stable Diffusion, and ChatGPT, you’ll start to get an intuition for the types of prompts that produce the best results. Here are some prompt writing tips I’ve picked up over time.

Describe the Scene

Set the stage by describing the scene you want the AI to generate. Be specific about settings, subjects, styles, etc.

Good example: “An oil painting portrait of a girl with red hair wearing a blue dress, standing in a sunny flower field on a summer day.”

Bad example: “Paint a pretty picture.”

Use Adjectives

Sprinkle descriptive adjectives throughout your prompt. Describe textures, colors, shapes, sizes, etc. This helps the AI render finer details.

Good example: “A still life painting of a smooth ceramic vase with a floral pattern containing brightly colored flowers with soft petals.”

Specify an Art Style

Referencing a specific art style helps the AI mimic stylistic elements like brush strokes, shapes, or palettes.

Good example: “A cubist portrait of a man wearing a fedora, by Pablo Picasso.”

Use Comparisons

Compare your subject to well-known people, places, or things. This gives the AI more context.

Good example: “A photo of a tabby cat with markings like a mini tiger.”

Set Parameters

Define the image dimensions, crop, angle of view, aspect ratio, etc.

Good example: “A full body portrait of a ballerina, shot from below with a 16:9 widescreen aspect ratio.”

Leverage Weights

Wrap keywords in double brackets [[]] to reduce their influence. The AI will still consider them, but not as strongly. This prevents some elements from overpowering others.

Good example: “A still life painting with a bowl of fruit [[including oranges and apples]] and a vase of flowers.”

Use Negative Prompts

Specify what you don’t want the AI to include using “(-)” or “no”. This reduces unwanted outputs.

Good example: “A beach scene with palm trees and white sand, no people, high detail, 4k resolution.”

Checkpoint Mixing

Reference multiple art styles by listing them separated by a colon (:). The AI will blend them together.

Good example: “A portrait of a wizard, blended art style: oil painting:digital art.”

Prompt Chaining

Chain prompts together with a colon to make mini stories. The AI will attempt to maintain consistency across images.

Good example: “Post apocalyptic city ruins:soldiers patrolling the rubble:scavengers hunting for supplies.”

Creative Liberties

Don’t be afraid to try crazy, silly, or unexpected concepts! The AI will often surprise you with creative interpretations.

Good example: “An astronaut riding a unicorn on Mars, very detailed, digital art.”

Fix Common Issues

If images turn out incorrectly, analyze them to identify needed improvements, then update prompts accordingly. Refining prompts is an iterative process.

Good example:
First try: “A photo of a cat wearing sunglasses.”
The AI didn’t include sunglasses.
Second try: “A photo of a cat wearing black sunglasses covering its eyes.”
