  • 🎨 **Art Medium First**: Start your prompt by declaring the art medium to give the AI a clear impression of the style you want for the generated image.
  • πŸ“Έ **Focus on the Subject**: Clearly state the primary focus of the image, such as a beautiful woman in a white nightgown, to guide the AI towards the main subject.
  • πŸ‘₯ **Secondary Focus**: Include secondary elements like background details or other people to add depth to the scene.
  • πŸŒ† **Environmental Details**: Describe the setting, such as a high-end restaurant, to help the AI generate a more contextually rich image.
  • πŸ’Ž **Production and Lighting**: Mention specific production details like camera metadata and lighting to enhance the image's realism.
  • πŸ“ **Aspect Ratio Consideration**: Use aspect ratio to influence the composition and focus of the generated image.
  • πŸ” **Detailing the Scene**: Adding more details to the surroundings can prompt the AI to 'pan back' and include more of the scene.
  • πŸ“ˆ **Config Scale Adjustment**: Experiment with the config scale to drastically change the image and achieve desired effects.
  • πŸ”— **Use of Breaks**: Utilize the break command in longer prompts to help the AI refocus on important aspects.

Q & A

  • What is the main focus of Eric's video tutorial?

    -Eric's video tutorial focuses on how to effectively structure prompts for generating images using Stable Diffusion in Automatic 1111, providing guidance on creating detailed prompts to improve the quality of the generated images.

  • Why does Eric emphasize the importance of prompt structuring in AI image generation?

    -Eric emphasizes prompt structuring because different AI models like Stable Diffusion interpret prompts in various ways. Proper structuring ensures that the AI generates images that more closely align with the user's vision by providing clearer guidance and context.

  • What does Eric suggest about the placement of art medium in a prompt?

    -Eric suggests placing the art medium at the beginning of the prompt rather than at the end. This approach gives the AI a stronger impression of the desired artistic style, ensuring the final image aligns more closely with the specified medium.

  • How does Eric adjust the negative prompt weight in his example, and why?

    -Eric adjusts the negative prompt weight to a lower value to make it less heavy-handed, which he mentions doing on purpose for various reasons. This adjustment is likely to balance the influence of the negative prompt, allowing for a better-quality image generation.

  • What does Eric mean by 'Focus formatting' and how does it help in prompt structuring?

    -Focus formatting involves using parentheses and numbers to emphasize certain parts of a prompt. This method helps the AI focus more on these emphasized elements, making them more prominent in the generated image.

  • What role does specifying camera details play in the image generation process according to Eric?

    -According to Eric, specifying camera details helps because many AI models, including Stable Diffusion, were trained on images with metadata that includes camera information. Including such details can lead to better-structured and more balanced images.

  • Can you describe a mistake Eric made during his tutorial and how he corrected it?

    -Eric accidentally left a guide prompt in the input field while generating an image, which affected the output. He corrected this mistake by removing the guide prompt and re-rendering the image, ensuring that the results were solely based on the intended prompt.

  • What is the significance of the 'break' command in Eric's prompt strategy?

    -The 'break' command is used to help the AI refocus on different parts of a long prompt, especially when the prompt exceeds a certain length. This helps maintain clarity and focus in the image generation process, even with complex prompts.

  • How does Eric ensure that his prompts are effective in creating detailed and realistic images?

    -Eric ensures effectiveness by structuring prompts that specify not only the main subject but also detailed secondary elements and the environment. He uses a methodical approach that includes focusing on art medium, primary and secondary details, and lighting.

  • What advice does Eric give for handling long prompts in image generation?

    -Eric advises using the 'break' command to help the AI manage long prompts better and maintain focus on all specified details. He also suggests using focus formatting to highlight important aspects, ensuring they are not overlooked by the AI.



🎨 Prompting Techniques for Stable Diffusion

In this video, Eric from Alchemy discusses his approach to crafting prompts for stable diffusion in AI-generated images.

πŸ’‘Stable Diffusion

Stable Diffusion is an AI model used for generating images from textual descriptions, known as prompts. In the video, Eric discusses how to effectively use prompts with Stable Diffusion to create desired images, emphasizing the importance of clear and structured prompts for the AI to understand and generate images accurately.


Prompting refers to the process of providing a text input or description to an AI system to guide its output. In the context of the video, Eric talks about the art of crafting prompts for Stable Diffusion, which involves specifying details about the image's subject, style, and environment to achieve the best results.

πŸ’‘Juggernaut XL

Juggernaut XL is a version of the AI model used in the video for generating images. It is mentioned as the tool that Eric uses to create images from the prompts he structures. The version number 'five' suggests it's an updated or specific iteration of the AI model.

πŸ’‘Negative Prompt

A negative prompt is a technique used in AI image generation where the user specifies what they do not want to appear in the generated image. Eric uses negative prompts to refine the image generation process, scaling down the negative prompt weight to avoid over-influence and maintain a chance for a high-quality image.

πŸ’‘Art Medium

The art medium refers to the material or technique used in creating an artwork, such as watercolor, photography, or digital art. In the video, Eric emphasizes the importance of declaring the art medium at the beginning of the prompt to guide the AI towards generating images in the desired artistic style.

πŸ’‘Focus Formatting

Focus formatting is a method used in crafting prompts to draw the AI's attention to certain parts of the description. It often involves using parentheses and numbers to amplify the importance of certain features in the generated image. Eric discusses using focus formatting to ensure the AI prioritizes key elements of the image.

πŸ’‘Aspect Ratio

Aspect ratio refers to the proportional relationship between the width and the height of an image. Eric talks about adjusting the aspect ratio to influence the composition of the generated image, such as making it wider or taller to fit more content as desired.


Metadata is data that provides information about other data. In the context of AI image generation, metadata can include details like camera information. Eric mentions that including camera details in the prompt can lead to more balanced and structured images, as the AI was trained on images with such metadata.
