GPT Image 1.5 (left) vs Gemini Nano Banana Pro (right) Prompt; Create a monochrome studio portrait of a man. Use minimal lighting with soft falloff so the focus stays entirely on him, with subtle gradients and deep shadows shaping his face. The composition should be a tight-medium shot against a clean, distraction-free background. He’s dressed in a casual, stylish outfit—like a simple tee or sweatshirt with light texture that works well in black and white.
