Advanced Midjourney Techniques: Seed Values, Custom Aspect Ratios, and Negative Prompts

Advanced Midjourney techniques involving seed values, custom aspect ratios, and negative prompts allow precise control over AI-generated images, enhancing creativity and consistency.

Seed Values

• A seed value in Midjourney is a numerical parameter that controls the randomness of image generation. Using the same seed with the same prompt and parameters produces consistent, reproducible images.
• This is useful for iterative refinement or creating variations with controlled randomness.
• While the exact syntax for seeds isn't detailed in the search results, it is a common advanced parameter in AI image generation tools to fix the random number generator state.

Custom Aspect Ratios

• Midjourney allows users to specify custom aspect ratios to control the width-to-height ratio of the generated image.
• Common aspect ratios include 1:1 (square), 4:3, 16:9 (widescreen), and 9:16 (portrait).
• The syntax to set aspect ratio is --ar width:height. For example, --ar 16:9 creates a widescreen image.
• Custom aspect ratios help tailor images for specific uses like social media posts, wallpapers, or print formats.

Negative Prompts

• Negative prompts use the syntax --no followed by elements you want to exclude from the image.
• For example, --no palm trees removes palm trees from a beach scene.
• This technique reduces unwanted elements and improves prompt precision, cutting down on unnecessary iterations.
• Negative prompts are best used iteratively: generate an image, identify flaws, then add targeted negative prompts to refine the next generation.
• Combining strong positive prompts with negative prompts yields the best results.

Additional Advanced Techniques (Contextual)

• Prompt stacking and weight distribution: You can combine multiple prompts with weights to emphasize or de-emphasize parts of the prompt, e.g., subject::1.5 background::-0.5.
• Quality and stylistic control: Parameters like --q for quality, --s for style strength/detail, and --c for chaos (randomness) allow fine-tuning.
• Focus and depth control: Parameters like focus-100 on a subject and depth for scene layering help with composition.
