产品视觉 GPT Image 2 提示词：Magnetic Iron Filings Logo Scene

Transform the {argument name="logo source" default="uploaded logo"} into a hyper-realistic scene where the logo silhouette is formed by {argument name="material" default="iron filings"} reacting to a magnetic field. The logo must keep its exact shape and proportions, appearing as if a magnet shaped like the logo (or hidden beneath the surface) is influencing the filings to align naturally into that recognizable formation. Material details: Fine iron filings with sharp, spiky, needle-like structures. Dense clustering along magnetic field lines forming the logo silhouette. Variation in density — thick near magnetic poles, thinner outward. Matte dark metallic texture with subtle reflections. Physics behavior: Iron filings must follow realistic magnetic field patterns — radial and curved lines forming spikes and ridges. Stronger attraction zones create thicker, raised clusters. Outer areas show softer, more dispersed alignment. Natural randomness and slight irregularity — no perfect edges. Some loose filings scattered beyond the main shape. Surface interaction: Flat surface such as a {argument name="surface type" default="lab table, glass plate, or matte black tray"}. Filings resting on surface but visibly lifted in areas due to magnetic force (spiky texture). Subtle dust and micro particles around. Environment & human presence: Realistic classroom, science lab, or creative studio environment. A person partially visible — hands holding or moving a magnet beneath the surface or nearby. Possibly a child or adult observing or interacting (adds emotional curiosity). Other subtle elements: notebooks, tools, or lab items out of focus. Lighting: Directional overhead light creating shadows from raised filings. Subtle highlights on metallic edges. Balanced natural or indoor lighting. Atmosphere: Curiosity. Discovery. Educational yet visually satisfying. Quiet but engaging moment. Camera & composition: Top-down or slightly angled close-up view. Logo clearly visible through iron filing formation. Human hands or interaction slightly off-center for storytelling. Format: Aspect ratio: STRICT 4:5 vertical. No text overlays. Style: Hyper-real macro + environmental photography. Physically accurate magnetic behavior. Cinematic yet grounded realism.
