Ultra-photorealistic 8K photography of a young woman holding a glass of lemonade in her hand, isolated against a vibrant blue background. The glass is crystal clear, filled with ice cubes, fresh lemon slices, and condensation sparkling in soft natural light. The woman wears casual summer attire, her demeanor calm and focused, with sharp focus on the glass in her hand. The composition is clean and minimalistic, with a smooth gradient blue background providing depth and balance. --ar 4:3
