Introduction to Prompt Crafting

Prompt crafting is an essential skill for creating AI-generated art. Many people struggle with understanding how their words affect the final output, often resorting to copying others' prompts without grasping the underlying principles. This article aims to guide you through a step-by-step process of creating effective prompts, focusing on simplicity and gradual refinement.

Setting Up Invoke AI

To follow this tutorial, you'll need to use Invoke AI, a powerful AI art generation tool. The author recommends using the 536mix version 1.3 model, which can be found on Civitai. The tutorial provides specific settings for Invoke AI, including steps, CFG scale, dimensions, sampler, and other parameters to ensure consistent results.

Starting with a Simple Prompt

The process begins with a simple prompt: 'professional photo, woman floating in space'. This sets the foundation for the image we want to create. The author emphasizes the importance of starting with a basic concept and building upon it, rather than overwhelming the AI with complex instructions from the start.

Refining the Prompt

As we progress, we refine the prompt by adjusting key terms and their weights. For example, changing 'floating' to 'flying' and increasing its importance using parentheses and a numerical value: '(flying in space)1.4'. We also add descriptors like 'ornate gown' to better define the subject's appearance.

Adding Details and Flow

To enhance the image, we incorporate more details such as 'long hair' and 'flowing hair'. The concept of 'flow' becomes a recurring theme in the prompt, helping to create a more dynamic and visually interesting result. We also introduce elements like feathers to add complexity to the composition.

Incorporating Background Elements

To complete the scene, we add a 'nebula background' and later refine it to a 'flowing nebula background'. This ties the subject to her environment and enhances the overall composition of the image.

Fine-tuning the Portrait

To improve the quality of the portrait, we add phrases like 'detailed face' and 'detailed eyes'. These additions help bring the subject closer to the viewer and improve the overall quality of the facial features. We also experiment with changing the hair color to blonde, which unexpectedly affects the entire composition.

The Importance of Minimal Negative Prompts

The author stresses the importance of using negative prompts sparingly. In this case, only one negative prompt is used: 'planet'. This minimal approach leads to a surprising and pleasing result, demonstrating that sometimes less is more when it comes to guiding the AI.

Conclusion and Tips

The tutorial concludes by summarizing the key principles of effective prompt crafting: starting simple, gradually refining the prompt, using descriptive terms strategically, and minimizing negative prompts. The author encourages readers to experiment with this approach, emphasizing that understanding how to guide the AI is more valuable than relying on complex, pre-made prompts.
