Stable Diffusion Prompt Engineering Guide
Because the Stable Diffusion generator has become a popular choice for artists generating artificial intelligence (AI) pieces, you need to understand how it works so that you can take full advantage of it to grow your art career. One of the main aspects of this AI art generator that you need to master is how to create effective text prompts.
Stable Diffusion relies on text prompts to generate the desired images. So, if you use the wrong prompts, you’ll end up with erroneous images. If you’re new to this AI art generation model and you don’t know the ideal Stable Diffusion prompt length or the right words to include in your prompts, this article offers you the ultimate Stable Diffusion prompt engineering guide.
What Is a Stable Diffusion Prompt?
A prompt is a set of instructions fed to a deep-learning algorithm to produce a definite output. In AI art generation, prompts are fed to the Stable Diffusion model to generate images based on the specific prompts. Here’s a good example of a Stable Diffusion prompt: “Generate a picture of a black cat on a kitchen top.”
In short, a prompt is a text description of a subject that you wish to create using an AI image generator like Stable Diffusion. You can think of it as the communication medium for the Stable Diffusion model because it conveys your ideas about the kind of AI images you want to generate by describing all the elements of each image.
A Stable Diffusion prompt can be as simple as a single line of vague text or several lines of text, depending on how detailed your image is. Sometimes, you can use emojis and images as prompts for maximum output–just make sure that the prompts you use are clear and detailed enough to guide your AI image generator.
You also need to understand that Stable Diffusion allows you to input negative prompts to let the model know the elements you want to remove from the final output. For instance, if you want to create an image of a black cat sitting on a kitchen top without a “bowl of apples” in the image, “bowl of apples” will be your negative prompt. So, it’s important to be aware of Stable Diffusion negative prompts and how to create them.
Stable Diffusion Prompt Engineering Guide
Before you start engineering your Stable Diffusion prompts, you need to understand some important rudiments like the most effective sentence structure. A good prompt should contain the most basic elements of a complete sentence, including a noun, a verb, and an adjective. These elements are important for generating interesting subjects.
Secondly, you should try as much as possible to include at least three words in your text prompts to give your Stable Diffusion model a clear context. The more words you use, the easier it is for the AI art generator to understand the context of your preferred image–within reason.
Adjectives are very important in prompt engineering because they infuse feelings into your work, making it more realistic and colourful. Therefore, try to include multiple adjectives in your prompts. If you wish to add a watermark to your final image, you can add your name to the text prompt–this also helps to mimic your style.
Speaking of style, you need to have a particular style of creating prompts for your AI images. The most popular styles include minimalism, symmetry, surrealism, modern, and more. Lastly, don’t include vulgar or banned words in your text prompts to avoid getting banned by Stable Diffusion.
Remember that a text prompt for AI image creation assumes the same structure. This structure contains three main ingredients: the subject; details and surroundings; and style, artist, and media type.
In short, this structure should answer three fundamental questions: What do you see? What about it? How does it look? Here’s a perfect example of a prompt structure: “An eagle – on a tree branch eating a dead rabbit - expressionist painting.”
