Google Gemini Nano Banana 2 对比 GPT Image 2

Google Gemini Nano Banana 2 vs GPT Image 2 Prompt; Concept & Composition Primary Subject: A man captured in a clean side-profile, dressed in a tailored suit and a vintage 1940s-style fedora. His posture is composed and confident, evoking classic noir protagonists. Dissolve Effect: The lower portion of his body gradually breaks apart into elongated, dripping ink trails. These streaks extend downward in uneven, organic lines, as if the figure is bleeding into the canvas. Graphic Accent: Behind his head and upper torso sits a bold, perfectly round red disc. It acts as a visual anchor, resembling a halo or rising sun, contrasting sharply with the monochrome subject. Visual Style & Palette Color Approach: Limit the palette strictly to deep black, vivid red, and a soft off-white/cream tone for a clean, striking look. Photographic Feel: The subject should resemble a high-end black-and-white editorial shot inspired by film noir, crisp details, shallow depth of field, and rich tonal contrast. Background Texture: Use a subtle paper or canvas-like backdrop in off-white to give the image a tactile, print-like quality. Lighting & Mood Lighting Setup: Dramatic Rembrandt-style lighting, with strong highlights shaping the face and pronounced shadows defining the cheekbones and jaw. Overall Tone: Moody, contemplative, and slightly ominous,suggesting tension and quiet intensity. Framing & Format Layout: Vertical composition, designed like a modern art poster. Spacing: Keep generous empty space on both sides to emphasize symmetry and the central figure.
