Q & A

  • What is the main issue with the initial results produced by the AI when using a general prompt like 'man in a suit'?

    -The main issue with the initial results is that they often include unpleasing outcomes such as deformities, double heads, and a wide variance in the types of images produced, due to the lack of specificity in the prompt.

  • How can the quality and coherency of the AI-generated images be improved?

    -The quality and coherency can be improved by using more specific and descriptive prompts, utilizing adjectives to describe nouns, and considering the aspect ratios on which the AI was trained to reduce the likelihood of deformities.

  • What is the significance of the seed in the AI image generation process?

    -A seed is a random number generated by the AI which helps to keep certain characteristics of the image consistent. Using the same seed allows for tweaks and adjustments without committing to a single pose or outcome.

  • What is a negative prompt and how is it used in the AI image generation process?

    -A negative prompt is used to identify and exclude undesired elements from the generated image. It helps to refine the output by specifying what should not be included, such as too many buttons or a cropped head.

  • How can the foundational prompt be enhanced to produce better images?

    -The foundational prompt can be enhanced by adding specific details about the subject, the environment, and the desired artistic style. This includes the use of modifiers and tags that would be associated with the desired image.

  • What is the impact of prompt order on the AI-generated image?

    -The order of the words in the prompt has a significant impact on the generated image. Prioritizing certain elements by placing them at the front of the prompt can improve the output. If the results are unpleasing, rearranging the words can lead to better images.

  • How can the use of artistic styles and camera models influence the final image?

    -Using specific artistic styles and indicating camera models can enhance the image with a more professional and polished look. These elements can also influence the characteristics inherited by the generated image.

  • What is the role of image strength when using filters like realistic vision or RPG in the image refinement process?

    -Image strength determines how much the filter alters the original image. Adjusting the image strength can help achieve a balance between refinement and maintaining the original details, leading to more realistic and improved outputs.

  • Why is experimenting with different seed numbers important in the image generation process?

    -Experimenting with different seed numbers allows for variations in the generated images and can help fix existing problems or provide different perspectives. It offers more flexibility and control over the final output.

  • What is the recommended approach to refining the AI-generated images?

    -The recommended approach is to develop a good foundation for the images by using specific prompts, modifiers, and seeds. This provides a more controlled and efficient way of achieving desired results compared to randomly generating multiple images.

  • How can the AI image generation process be likened to a creative journey?

    -The AI image generation process is a creative journey because it involves starting with a basic idea, refining it through specific prompts, experimenting with seeds, and adjusting filters to achieve a desired outcome. It requires exploration, creativity, and fine-tuning much like an artist would with their craft.
