Under Glass Floor Perspective Shot

Camera placed directly beneath a {argument name="surface" default="completely transparent glass floor"}, pointing straight up. Pedestrians walk across the surface above. {argument name="background" default="Pure blue sky"} fills the background. No buildings, walls, or edges in frame. The glass is perfectly seamless and nearly imperceptible. Extremely close viewpoint to the underside of the walking figures. People moving mostly left to right. {argument name="foreground" default="Shoe soles"} fill the foreground up close.
