What are negative prompts in AI art?

Negative prompts are text prompts that instruct the AI model that it should not include certain elements in its generated images.

How do negative prompts modify AI art images?

Negative prompts can provide additional guidance to the AI model, eliminating some resulting images that don’t fit the user’s needs.
How can negative prompts help remove unwanted elements from AI art?
Negative prompts help remove unwanted elements by eliminating them from the AI art generation. If your prompt is “a family gathering at home for dinner with their dog,” and you like every type of dog except pugs, you can type “pug” in the negative prompt field, and images including pugs will be excluded from influencing the generation.
Can negative prompts be used to emphasize certain aspects of AI art?
Yes. You can use negative prompts to emphasize certain aspects of the positive prompt. If you want to create an image of a vibrant, brightly colored garden lake with flamingos and tropical flowers, for example, you can add negative prompts like “muted colors,” “shadows,” and “dull green” to enhance the brightness of the image.
