Ultra-realistic cinematic image from a slightly tilted courtside perspective with a natural 50mm look. A smartphone lies on a natural wooden table with visible wood grain. The phone screen is transformed into a pristine blue professional tennis court, complete with fine scratches and chalk marks. Realistic miniature tennis players are serving, volleying, and diving for shots. The phone surface shows visible fingerprints, subtle smudges, and micro-scratches on its edges. Dramatic directional stadium-style side lighting casts strong highlights and long shadows, with soft reflections of floodlights on the phone glass. Crisp, high-contrast, shallow depth of field, sharp focus on the phone and court, rich texture, photorealistic.
