GPT Image 2.0 提示词 - 专业播客麦克风海报

High-resolution poster showing a professional studio condenser microphone suspended in a shock mount at the top-right, angled down into frame; microphone finish matte black with metallic highlights, visible textured mesh head with fine woven grille and subtle dust particles catching light. Background is a smooth gradient from deep tangerine at the top to warm orange at the bottom, framed by a thin pale-orange inner border and rounded corners, subtle vignette. Large bold condensed sans-serif headline on the left, stacked two lines reading 'PROFESSIONAL' (top) and 'PODCAST' (below) in clean white, tight leading, full-bleed typographic treatment occupying roughly left 60% of the canvas. Script accent 'Audio editing & mastering' in glossy black brush-script overlapping the lower-right of the word 'PODCAST' with slight drop shadow and hand-written flourish. At the very bottom center, small all-caps sans-serif tagline in black: 'Crystal Clear Sound That Engages Listeners'. Composition uses strong diagonal from the mic to text, generous negative space to left, balanced visual weight between mic and typography. Lighting: directional soft key light from upper-left producing crisp specular highlights on mic frame and subtle soft shadows; gentle rim light on the right edge of the microphone to separate it from background. Color grade: warm, high-saturation oranges and neutral blacks, overall contrast medium-high with preserved shadow detail. Textures: mic mesh crisp and detailed, shock mount cables and screws slightly reflective with micro-scratches. Style: modern minimalist promotional poster, photorealistic microphone with graphic typographic layout, high depth-of-field, clean vector text. Use sharp focus on microphone and headline type, slight chromatic aberration and film-grain (very low) for tactile finish. Camera: 50mm-equivalent focal length, f/4, slight perspective tilt, crop to vertical mobile-story aspect ratio."Negative prompts / avoid:Do not use low-resolution, pixelated, blurry microphone or typographyAvoid busy backgrounds, patterns, or gradients with bandingNo additional people, faces, logos, or identifiable brandsNo over-saturated neon colors (keep warm orange palette)Avoid heavy noise, extreme HDR halos, or unrealistic reflections on micDo not change the headline wording or composition layoutUsage, aspect ratio and technical suggestions:Sampling: 50-150 steps depending on sampler; CFG scale 6.5–8.5 (for SD), guidance 7–9 for other modelsSeed: set a fixed seed for reproducibility or leave random for variationsFor img2img edits: set denoising 0.3–0.5 to preserve composition while refining detailsFor inpainting: mask area you want text/tint changes, keep mic area locked to preserve photoreal detail. 2:3 aspect ratio
