The prompt

Prompt

A brass and copper steampunk submarine with riveted plating and a large domed porthole, descending into a bioluminescent deep-sea trench, glowing jellyfish and anglerfish illuminating the darkness around the hull, steam vents releasing bubbles from the submarine's pipes, a mechanical claw arm extended from the bow examining a glowing coral formation, the trench walls visible in the background with faint purple bioluminescence, no text, no letters --ar 16:9 --stylize 250

How to use this prompt

  1. 1

    Open the generator that matches the model and version above, and start a new image rather than editing an existing one.

  2. 2

    Set the output to 16:9 and apply the settings shown in the parameters panel — together those produced the 768 × 432 image on this page.

  3. 3

    Paste the prompt exactly as written. Changing the wording changes the image, so copy it before you edit.

  4. 4

    Generate, then change one thing at a time. The result will not be pixel-identical to the image on this page, because no seed is recorded for it.

Midjourney takes the aspect ratio as a parameter appended to the prompt rather than as a separate control, written as --ar 16:9, and --stylize followed by a number controls how far the model pushes its own aesthetic. Append both to the end of the prompt text instead of looking for fields for them.
