Chân Dung Ảo Ảnh Quang Học Thân Vô Hình

A surreal optical illusion photo of [a man in casual clothes] seated on a wooden park bench in [a sunny city park]. He holds [an empty rectangular wooden frame] at chest level where his torso should be. Only his head and face above the frame, his hands and forearms gripping the frame's edges, and his legs below the bench seat are visible. Inside the wooden frame, the park background continues seamlessly with perfect alignment—showing the bench slats, green grass, trees, and walking paths—making his torso appear completely invisible and transparent. Clear natural daylight, sharp focus on the frame edges and background continuity.
