Day and Night Split Portrait Prompt for Nano Banana Pro

A highly detailed prompt for generating a hyper-realistic 8K portrait using Nano Banana Pro, featuring a vertical split down the center of the face. The left side represents day (warm golden light, blue sky, sunflower) and the right side represents night (cool blue moonlight, dark sky, stars, fireflies). The prompt specifies camera settings (85mm f/1.8, close-up) and distinct lighting temperatures (3200K vs 7000K) for a sharp juxtaposition. Via YouMind OpenLab prompt library (MIT).
