🎨 Utilizing Prompt Weights for Image Generation

This paragraph delves deeper into the concept of prompt weighting, explaining how it can be used to influence the AI's image generation process. The speaker illustrates the use of parentheses to emphasize certain words in the prompt, which the AI then prioritizes more highly. The paragraph further explains the concept of 'prompt waits,' where additional weight is given to specific words by enclosing them in double parentheses, tripling their influence on the image generation. The speaker also introduces another method of prompt weighting by assigning numerical values to words using colons, with higher values leading to greater emphasis on those features. The speaker then demonstrates how adjusting the weights can lead to more precise image generation, using the example of a woman with an emphasized black mini skirt and a handbag, requesting the AI to generate an image with these features in focus. The video also shows how to correct mistakes in the prompt by adjusting brackets, which are indicated by a red border.
