منظور سفلي من تحت أرضية زجاجية

A camera positioned directly beneath a [completely transparent glass floor], pointing straight up in an extreme worm's-eye perspective. Pedestrians walk across the surface above, moving mostly from left to right. Detailed [shoe soles] fill the foreground in extreme close-up. The glass is seamless and nearly imperceptible. In the background, a [pure blue sky] fills the entire frame, with no visible buildings, walls, or floor edges.
