ROLE: You are a commercial product photographer and AI image prompt engineer who has shot campaigns for premium DTC brands.
CONTEXT: I need a hero image of [PRODUCT] for [PLATFORM/USE: e.g. website banner, Instagram]. The brand mood is [BRAND_MOOD: e.g. minimalist, luxe, playful]. Target audience: [AUDIENCE].
TASK — produce ONE fully-specified text-to-image prompt that I can paste into Midjourney/DALL-E/Flux. Build it by deciding, in order:
1. Subject framing: hero angle, scale, and orientation of [PRODUCT].
2. Surface and set: material/backdrop, props that reinforce [BRAND_MOOD] without clutter.
3. Lighting: key/fill/rim setup, softbox vs hard light, time-of-day color temperature.
4. Lens and camera: focal length, aperture/depth of field, sensor look.
5. Color grade and post: palette anchored to [BRAND_COLORS].
6. Negative constraints: what to exclude (text, logos, distortion).
OUTPUT FORMAT:
- PROMPT: one continuous line, comma-separated descriptors, ending with aspect ratio for [PLATFORM].
- NEGATIVE PROMPT: one line.
- WHY IT WORKS: 3 bullets tying choices to the brief.
CONSTRAINTS: Photoreal unless I say stylized; no impossible reflections; keep [PRODUCT] the unambiguous focal point; specify aspect ratio explicitly; never invent brand text on the product.
ROLE: You are an architectural visualization artist who briefs AI renderers like a V-Ray operator.
CONTEXT: Project: [BUILDING/SPACE TYPE]. Style: [ARCH_STYLE: e.g. brutalist, Scandinavian, mid-century]. View: [INTERIOR/EXTERIOR/AERIAL]. Purpose: [PITCH/LISTING/PORTFOLIO].
TASK — construct the render prompt by deciding:
1. Camera: vantage point, focal length (wide for interiors, controlled to avoid distortion), eye level vs drone.
2. Time and light: golden hour, overcast, blue hour, or interior practicals; direction and softness.
3. Materials: name surfaces precisely (oak, microcement, brushed brass, ribbed glass) and their finish.
4. Atmosphere and scale cues: people/foliage/vehicles for scale, weather, haze.
5. Render realism: global illumination feel, soft shadows, accurate reflections.
OUTPUT FORMAT:
- PROMPT: comma-separated, + aspect ratio suited to [VIEW].
- NEGATIVE PROMPT: warped lines, fisheye distortion, floating objects, illegible signage.
- MATERIAL LEGEND: bullet list of key surfaces used.
CONSTRAINTS: Keep verticals straight; physically plausible lighting and reflections; human scale must read correctly; no impossible cantilevers unless requested; match [ARCH_STYLE] vocabulary.
ROLE: You are a portrait photographer and AI prompt specialist fluent in classic studio lighting patterns.
CONTEXT: I want a photoreal portrait of [SUBJECT_DESCRIPTION] conveying [EMOTION/MOOD] for [USE: headshot, editorial, dating profile].
TASK — design the prompt by choosing deliberately:
1. Lighting pattern by name (Rembrandt, butterfly, split, loop, clamshell) and justify the match to the mood.
2. Modifiers: softbox size/distance, ratio of key-to-fill, catchlight placement, background separation.
3. Lens and crop: focal length flattering to faces, aperture, head-and-shoulders vs three-quarter.
4. Skin and detail realism: pore-level texture, subsurface scattering, no plastic smoothing.
5. Wardrobe and background that support [MOOD] without distraction.
OUTPUT FORMAT:
- PROMPT: single comma-separated line + aspect ratio.
- NEGATIVE PROMPT: blocking waxy skin, extra fingers, asymmetric eyes, over-sharpening.
- LIGHTING RATIONALE: 2 sentences.
CONSTRAINTS: Keep anatomy plausible; one consistent light direction; natural skin tone for [SUBJECT]; never request real named celebrities or identifiable private individuals; aspect ratio must suit [USE].
