How to Write Effective Stable Diffusion Prompts
The ideal length of a Stable Diffusion prompt is between 3 and 60 words.
Longer prompts can be used, but they may be more difficult to interpret by the model and may result in less realistic images.
There are differences between SDL. - amd SDO.-Prompts.
SDL.-Prompts are separated in Negative and Positive Prompt.
'Sample:
$$POS=Red Ufo, Galaxis
$$NEG=Green Ufo
SDO.-Prompts contain separated Terms that get a weight which can be positive or negative.
' Sample
$$PRO=Red Ufo(0.5),GreenUfo(-0.5),Galaxis(0.5)
Here are some tips for writing effective Stable Diffusion prompts:
•A rule of thumb can be: (subject)(style), (action/scene), (artist), (filters)
•Be specific. The more specific you are, the more likely the model is to generate an image that matches your expectations.
•Use keywords. Keywords are words or phrases that describe the features you want to see in the image.
•Use negative prompts. Negative prompts tell the model what you don't want to see in the image.
•Use brackets and parentheses. Brackets and parentheses can be used to group keywords together.
•Use weights. Weights can be used to control the importance of different keywords.
•The maximum usable length of a Stable Diffusion text prompt is purportedly 77 tokens. This means that the prompt can contain up to 77 words, but each word can be made up of multiple tokens. For example, the word "cat" is a single token, but the word "kitten" is two tokens.
It is important to experiment with different prompt lengths to see what works best for you. Some people find that shorter prompts are more effective, while others find that longer prompts are more detailed. The best way to find the perfect length for your prompts is to try different things and see what you get.
The order of the words in a prompt for Stable Diffusion can have a significant impact on the resulting image. For example, if you want to generate an image of a cat, you might write the prompt as follows:
"A cat sitting on a windowsill"
However, if you change the order of the words, you might get a different result. For example, if you write the prompt as follows:
"A windowsill with a cat sitting on it"
The resulting image might be more focused on the windowsill, with the cat being smaller and less prominent.
This is because the order of the words in a prompt tells the model what to pay attention to first.
When the model sees the word "cat," it knows that it should start generating an image of a cat.
However, when the model sees the word "windowsill," it knows that it should also generate an image of a windowsill. The order of the words determines which object the model focuses on first.
In general, it is best to put the most important objects in the prompt first.
This will help the model to generate images that are more accurate and realistic. However, you can also experiment with different orders of words to see what works best for you.
Here are some other tips for writing effective Stable Diffusion prompts:
•Use specific keywords. The more specific you are, the more likely the model is to generate an image that matches your expectations.
•Use negative prompts. Negative prompts tell the model what you don't want to see in the image.
•Use brackets and parentheses. Brackets and parentheses can be used to group keywords together.
•Use weights. Weights can be used to control the importance of different keywords.
Creating the Perfect Prompt: A Comprehensive Guide
The creation of an effective prompt is an art form, involving several key components that guide the AI in generating the desired output. Here's a breakdown of these key components:
1. **Subject (Raw Prompt)**: This is the fundamental part of the prompt. It's the primary object or theme you want the AI to focus on. It's the "what" of your prompt. For example: "a black horse".
2. **Style**: The style determines the overall aesthetic and feel of the generated output. If no style is specified, the AI typically chooses the most common style associated with the raw prompt. For instance, if you're generating an image of a landscape, the AI might default to a realistic or oil painting style. Pairing the raw prompt with a well-chosen style can often yield satisfying results.
3. **Action/Scene**: These elements describe what the subject (raw prompt) is doing (action) and where it is located (scene). For example: "jumping in the forest".
4. **Filters**: Filters are the finishing touches you add to your prompt to achieve a specific look. For instance, adding "trending on Artstation" might give your image an artistic flair, while "Unreal Engine" might enhance the realism of the lighting. Some examples of filters are: highly detailed, surrealism, smooth, sharp focus, matte, elegant, illustration, digital paint, dark, gloomy, 8k, 4k, ambient lighting, and epic composition.
Remember, you can be creative and add any filter that aligns with your vision.
Here's a final example, combining all these components:
"Realistic art of a black horse, jumping in the forest, by Marc Simonetti, with fog, centered, symmetry, painted, intricate, volumetric lighting, beautiful, rich deep colours, masterpiece, sharp focus, ultra detailed, 4k."
Here are some additional examples incorporating all four components: subject, style, action/scene, and filters:
1. "A photorealistic image of a golden robot girl, walking through a bustling city at night, in the style of Syd Mead, with neon lighting, rain-soaked streets, sharp focus, dramatic shadows, and 4k resolution."
2. "An impressionist painting of a tranquil lake, with a pair of swans gliding peacefully at sunset, inspired by Monet, featuring warm colors, soft focus, gentle ripples, and the day's last light reflecting off the water."
3. "A surrealistic digital illustration of a futuristic spaceship, soaring above a sprawling alien metropolis, in the style of H.R. Giger, with intricate biomechanical details, a monochromatic color scheme, stark contrast, and 8k resolution."
4. "A fantasy art of a majestic dragon, perched on a snow-covered mountain peak, in the style of John Howe, with breathtaking panoramic views, vibrant colors, detailed scales and textures, and a dramatic lighting."
5. "A hyperrealistic 3D render of an underwater city, teeming with futuristic structures and exotic sea creatures, in the style of Alex Roman, with photorealistic lighting, detailed architecture, diverse marine life, and a 4k resolution."
Remember, you can mix and match these components in various ways to achieve different effects and moods. The possibilities are virtually endless!
With this guide, you're now equipped to craft effective prompts that can guide the AI to generate the output that aligns with your vision. Happy prompting!
