Romantic Noir Couple Posing Against Abstract Neon Background

Use this particular prompt with version 5.2 of Midjourney, specifically. If you like the characters and don't want a variety of new characters in your shot, simply specify the Midjourney parameter for character reference that guarantees consistency: --cref + the image URL of this image (right click the image, copy the URL, then append that to the end of your prompt). At this point, your prompt might look something like: a photo of a synthwave power couple, futuristic, dynamic, unique --ar 16:9 --v 5.2 --cref (URL of this image).

Within luma, simply upload your image, check the 'enhance prompt' box, press the arrow to start your generation, and you're all set! There's no need to add a text prompt to your image prompt in this particular case.
