Split screenสองช่วงเวลาในเฟรมเดียว

Split screen: a single frame divided by a sharp vertical line down the center, no gradient, no shadow. On the left half, a young woman in a linen dress walks steadily through a golden sunflower field, shot with a 35mm lens, her hand brushing the tall stalks. On the right half, an older man on a bicycle rides along a dirt path at the edge of the same field, shot with a 50mm lens, dust rising behind his wheels. Both actions run at the same natural speed under warm late afternoon light, and the dividing line stays perfectly still while each half moves independently. No text.
