The Illuminazione Camera in PES 2012 introduces more realistic lighting effects to the game. The developers at Konami have implemented a more advanced lighting system that simulates the way light behaves in real-life soccer stadiums. The lighting effects are now more nuanced, with subtle shading and shadowing that adds depth to the game environment. The illumination of the camera also creates a more immersive experience for the player, making them feel like they are actually on the pitch.
