Old staircase architectural photograph

Close, low-angle architectural photography of an old staircase in 16:9 format, the stairwell filling roughly the lower half of the frame and rising from the lower-left toward center, with a wrought-iron banister on the left and worn wooden treads visible in the foreground. The background occupies the upper half of the frame and contains generous negative space in the upper-right where angular shadow patterns fall across a faded plaster wall. Strong directional side-light from the right casts hard, graphic shadows down the risers and across the landing, producing high-contrast stripes and crisp rim highlights on the metalwork. Textures are specific: peeling paint flakes around the newel post, scuffed wood grain on each tread, rust speckles on iron filigree and faint damp stains on plaster. Compose and crop for 16:9 horizontal poster or wallpaper use, keeping the staircase diagonally dominant and leaving room for negative space in the top-right two-thirds. Use moderate depth so the nearest treads are sharp and the upper stair fades softly into shadow to emphasize scale and texture.
