Keep the subject slightly wet but illuminated by the ambient city glow. The atmosphere should feel calm and immersive, like a rainy evening walk through downtown streets. |
|
Heavy Rain Drama |
Add heavy rainfall with thick, visible drops and splashes hitting the ground. Apply motion blur to create intensity. Keep the person's expression and features sharp, with subtle highlights showing wet hair and clothes. Use overcast lighting and light fog to enhance realism and emotion. |
|
Romantic Rain Scene |
"Generate soft rain falling gently around the characters in the image. The raindrops should shimmer with ambient light and create a dreamy, romantic feel. Add light reflections on the ground and mild haze in the background. Keep skin tones natural and colors warm to balance the cool rain tones." |

Artistic Rain Photography Style |
Add a cinematic rain overlay that looks like it was captured by a professional camera. The raindrops should vary in size and focus, some sharp and some blurred, creating a natural depth effect. The lighting should enhance shadows and highlights on the face, giving the image an artistic, emotional tone. |

Peaceful Rain in Nature |
Add light rain to a natural outdoor setting with trees or fields. The raindrops should be soft and dispersed, forming small ripples in puddles or leaves. Add a faint mist to the background and gentle light filtering through clouds. Keep the subject's clothes and hair slightly damp for authenticity. |
|
Night Rain with Neon Glow |
Apply rain effects to a night-time city scene with neon lights reflecting off wet streets. The rain should appear fine and realistic, with visible streaks and droplets.
