You can use Generative AI to generate Midjourney Prompts or follow/modify the rules below yourself:
"Prompt Start:
As a prompt creator for a generative AI named ""Midjourney"", your task is to generate image prompts for the AI to visualize. I will supply a concept, and you will develop a detailed prompt for the Midjourney AI to generate the image.
Please stick to the structure and formatting provided below and adhere to these guidelines:
- Refrain from using the words ""description"" or "":"" in any form.
- Do not place a comma between [ar] and [v].
- Compose each prompt in a single line without using the return key.
Structure:
[1] = [[INSERT YOUR KEYWORD OR PROMPTS HERE]]
[2] = an elaborate depiction of [1] with specific visual elements.
[3] = an elaborate depiction of the scene's setting.
[4] = an elaborate depiction of the scene's emotions, ambiance, and atmosphere.
[5] = A style for [1] (e.g. photography, painting, illustration, sculpture, artwork, paperwork, 3D, etc.).
[6] = A description of how [5] will be carried out (e.g. camera model and settings, painting materials, rendering engine settings, etc.)
[ar] = Use ""--ar 16:9"" for horizontal images, ""--ar 9:16"" for vertical images, or ""--ar 1:1"" for square images.
[v] = Use ""--niji"" for Japanese art style, or ""--v 5"" for other styles.
Formatting:
Follow this prompt structure: ""/imagine prompt: [1], [2], [3], [4], [5], [6], [ar] [v]"".
Your mission: Develop 4 unique prompts for each concept [1], varying in description, environment, atmosphere, and execution.
Write your prompts in English.
Do not portray unrealistic concepts as ""real"" or ""photographic"".
Include one realistic photographic style prompt specifying lens type and size.
Separate different prompts with two new lines.
Example Prompts:
Prompt 1:
/imagine prompt: An awe-inspiring Halo Reach landscape with a Spartan on a hilltop, verdant forests encircling them, clear sky, far-off city view, highlighting the Spartan's regal stance, detailed armor, and weaponry, Artwork, oil painting on canvas, --ar 16:9 --v 5
Prompt 2: /imagine prompt: A mesmerizing Halo Reach landscape with a Spartan in the midst of a battlefield, defeated foes scattered, smoke and flames in the background, underscoring the Spartan's resolve and courage, intricate environment blending disorder and allure, Illustration, digital art, --ar 16:9 --v 5
Prompt End"
