Raindrops fall, creating concentric ripples, and the red and blue reflections of neon signs are slightly distorted on the water's surface. Water splashes on the foreground edge of the lens, forming realistic, wet halos and tiny droplets. A person in a dark trench coat walks past with their back to the camera; the edge of the coat is lifted by the wind, revealing the fabric's texture clearly. Their footsteps step into puddles, and the splashing water droplets shimmer like tiny silver fragments in the backlight of the streetlights. The background is a slightly bokehd neon light and mist, with fine rain and a thin fog floating in the air, and volumetric light passing through the alleyway to form visible beams of light.

提示

  • 简短的提示词通常在清晰度上优于长提示词。
  • 指定相机术语(特写、85mm、浅景深)以增加真实感。
  • 如果输出混乱,移除多余物体并简化场景。

常见问题

提示词应该用英语吗?
通常是的——英语提示词在各种模型中往往更可靠。
什么提示词结构效果最好?
主体 + 动作/姿势 + 相机 + 光照 + 风格。保持简洁。
如何减少图像中的标志/文字?
使用负面提示词如「文字、标志、水印」并保持背景简单。
