  • ๐ŸŽจ **Art Medium First**: Start your prompt by declaring the art medium to give the AI a strong impression of the style you want.
  • ๐Ÿ“ธ **Primary Focus**: Clearly state the main subject and its details to ensure it's the focus of the generated image.
  • ๐Ÿ‘ฅ **Secondary Focus**: Include secondary elements like background characters or objects to add depth to the scene.
  • ๐ŸŒ† **Environmental Details**: Specify the setting, such as a restaurant, and add details to help the AI create a more realistic environment.
  • ๐Ÿ’Ž **Production and Lighting**: Mention camera and lighting details to enhance the image's quality and realism.
  • ๐Ÿ“ **Aspect Ratio**: Adjust the aspect ratio to fit the scene you're trying to create, whether it's portrait or landscape.
  • ๐Ÿ” **Detailing the Scene**: Adding more specific details to the surroundings can prompt the AI to 'pan back' and include more in the image.
  • ๐Ÿ“ˆ **Config Scale**: Experiment with the config scale to drastically change the image and achieve different results.
  • ๐Ÿ”— **Use of 'Break'**: Include a 'break' in longer prompts to help the AI refocus on the remaining elements.
  • ๐Ÿ” **Focus Formatting**: Use focus formatting with numbers to amplify certain aspects of the prompt and draw the AI's attention.
  • ๐Ÿšซ **Negative Prompting**: Utilize negative prompts to exclude unwanted elements from the generated image, adjusting the weight for balance.

Q & A

  • What is the main focus of the video presented in the script?

    -The main focus of the video is to guide viewers on how to effectively craft prompts for stable diffusion in Automatic 1111, specifically focusing on how to use detailed and structured prompting to achieve better image generation results.

  • Why does Eric emphasize the importance of specifying the art medium at the beginning of the prompt?

    -Eric emphasizes placing the art medium at the start of the prompt to give the AI a strong impression of the desired artistic style, helping to prevent the generation of images that look like generic digital art when a specific style like charcoal drawing is intended.

  • What is a 'negative prompt' and why does Eric adjust its weight?

    -A negative prompt is used to guide the AI on what to avoid when generating an image. Eric adjusts the weight of the negative prompt to fine-tune its influence, aiming for a more balanced image output without being overly restrictive.

  • What does Eric mean by 'secondary focus and details' in a prompt?

    -In the context of a prompt, 'secondary focus and details' refer to the elements that should be included but are less dominant than the main subject. These could be background elements, additional characters, or objects that complement the primary focus.

  • How does the inclusion of specific camera details in the prompt affect the outcome of the image generation?

    -Including specific camera details helps the AI understand the intended quality and style of the photograph, leveraging the metadata from the training data. This can lead to images that are better structured and more aesthetically pleasing.

  • What is the purpose of using the 'break' command in longer prompts, according to Eric?

    -The 'break' command is used in longer prompts to help the AI refocus on different parts of the prompt, ensuring that all elements are considered during the generation process. This is particularly useful for maintaining attention on detailed aspects in extensive prompts.

  • What does Eric suggest to do if the AI does not center the subject as desired?

    -Eric suggests using terms like 'professional portrait photography' in the prompt, which implies a centered subject. This guides the AI to adjust the framing, focusing on the subject more precisely.

  • What improvements does Eric make to the prompt generator based on his experiences?

    -Eric adjusts the prompt generator to better structure prompts by ensuring related details are grouped together, and by emphasizing certain characteristics to ensure they are prominently included in the generated image.

  • Why does Eric choose to modify the prompt after generating an initial image?

    -Eric modifies the prompt after reviewing the initial image to correct any inadequacies or to enhance certain details, aiming to refine the image output according to specific artistic or thematic requirements.

  • How does Eric recommend using the 'focus formatting' technique in prompt crafting?

    -Eric uses the 'focus formatting' technique to emphasize certain aspects within a prompt, giving them a numerical priority that influences how the AI prioritizes these elements during image generation, leading to a more accurate depiction.

๐Ÿ’กStable 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 accordingly.


Prompting refers to the process of providing a text description to an AI system to guide it in generating a specific output. In the context of the video, Eric shares his techniques for crafting prompts that help the AI, specifically Stable Diffusion, to produce high-quality images that match the user's vision.

๐Ÿ’กArt Medium

The art medium is the material or technique used in any artwork to produce the visible aspects of the piece. In the video, Eric stresses the importance of declaring the art medium at the beginning of a prompt to guide the AI in generating images with the desired artistic style, such as watercolor or photography.

๐Ÿ’กNegative Prompt

A negative prompt is a part of the prompt that specifies what the user does not want to be included in the generated image. Eric uses negative prompts to refine the image generation process, instructing the AI to avoid certain elements or styles that are not desired in the final image.

๐Ÿ’กAspect Ratio

Aspect ratio refers to the proportional relationship between the width and the height of an image. In the video, Eric discusses adjusting the aspect ratio to influence the composition and focus of the generated image, ensuring that elements are included or excluded based on the desired outcome.

๐Ÿ’กFocus Formatting

Focus formatting is a technique used within prompts to emphasize certain elements that the user wants the AI to prioritize in the image generation. Eric demonstrates how to use focus formatting with numbers and parentheses to draw the AI's attention to specific parts of the prompt, ensuring those aspects are more accurately represented in the generated image.

๐Ÿ’กCamera Metadata

Camera metadata includes information about the camera settings and specifications used to capture a photograph. Eric mentions that including camera metadata in prompts can help the AI generate images that are more balanced and aligned with the desired artistic style, as the AI has been trained on images with such metadata.

๐Ÿ’กDynamic Range

Dynamic range in imaging refers to the ratio between the maximum and minimum measurable values of a certain quantity, typically the range between the lightest and darkest areas of an image. In the video, Eric includes terms like 'high dynamic range' in the prompt to guide the AI in creating images with a wide range of tones and details.

๐Ÿ’กVivid Colors

Vivid colors are bright, intense, and highly saturated hues that stand out in an image. Eric uses the term 'vivid colors' in the prompt to instruct the AI to generate images with rich and striking colors, enhancing the visual appeal and artistic quality of the final image.

๐Ÿ’กBreak Command

The break command is a function within the Stable Diffusion AI that helps the AI refocus on the remaining parts of a longer prompt. Eric uses the break command to structure his prompts effectively, ensuring that the AI does not lose focus on important details when generating the image.

๐Ÿ’กConfig Scale

Config scale is a parameter that can be adjusted in the AI's settings to influence the image generation process. Eric discusses the impact of changing the config scale on the final image, noting that it can drastically alter the output and is an important aspect of experimentation with the AI.
