πŸ“ Understanding Writing Prompts for Stable Diffusion

This paragraph introduces the concept of writing prompts for generating images using stable diffusion. It emphasizes the trial-and-error nature of the process and suggests a more analytical approach by selecting keywords from ten categories. The paragraph demonstrates how changing a single word in the prompt can significantly alter the generated image. It also provides an example of how specifying the subject, such as a 'woman,' and the desired medium, such as a 'photo,' can influence the output. Additionally, it explores the use of celebrity names and the technique of mingling two subjects to create a blend of images.


🎨 Exploring Art Mediums and Styles

The second paragraph delves into the importance of the 'medium' keyword in guiding the appearance of the generated image.

It provides resources for discovering different art styles and artists, such as the 'prompt Mania' website and the 'stable diffusion artist list,' and demonstrates how to use these to guide the image generation process.


πŸ€– Artist Names as Strong Keywords

This paragraph focuses on the power of using an artist's name as a keyword in the prompt. It illustrates how naming a specific artist can lead to images that reflect that artist's distinctive style.
