GPT Image 2 提示词指南：来自 OpenAI 官方 Cookbook 的 12 项技巧

提示词

A photorealistic candid photograph of an elderly sailor standing on a small fishing boat. He has weathered skin with visible wrinkles, pores, and sun texture, and a few faded traditional sailor tattoos on his arms. He is calmly adjusting a net while his dog sits nearby on the deck. Shot like a 35mm film photograph, medium close-up at eye level, using a 50mm lens. Soft coastal daylight, shallow depth of field, subtle film grain, natural color balance. The image should feel honest and unposed, with real skin texture, worn materials, and everyday detail. No glamorization, no heavy retouching.

提示词

A photorealistic editorial sports photograph. Scene: a coastal road at golden hour, ocean horizon visible on the right. Subject: a long-distance runner in a charcoal grey training kit, mid-stride, captured running directly toward the camera. Framing: medium-wide, full body visible, feet included. Viewpoint: low-angle from the asphalt, about 30cm above the ground. Composition: subject placed left of center with generous negative space on the right two-thirds for headline copy later. Lighting: warm golden hour key light from camera-right, soft fill from the ocean reflection on the left, long subject shadow falling toward the lower-left corner. Lens look: 35mm equivalent, slight motion blur on the rear leg only, sharp on the face and chest. No watermark, no on-image text.

提示词

A photorealistic billboard mockup at the side of a highway during sunset. The billboard is mounted on a steel pole structure, with cars passing on the road below. Billboard headline (EXACT, verbatim, no extra characters): "FRESH AND CLEAN". Below the headline in smaller type (EXACT): "since 1998". Typography: bold geometric sans-serif for the headline, light italic serif for the tagline, both centered, clean kerning, high contrast on a soft cream background. Ensure each text element appears once and is perfectly legible. No watermarks, no extra logos, no decorative elements that obscure the type.

提示词

A bold music festival poster, vertical orientation. Headline at the top third in large brushstroke kanji (EXACT, verbatim): "音楽の未来". Directly below in a clean geometric sans-serif (EXACT): "FUTURE SOUNDS FESTIVAL". Bottom strip in smaller white type (EXACT): "Shibuya O-EAST · Tokyo · June 14 2026". Dark background, electric teal and magenta neon glow. All text must be fully legible and correctly formed. No decorative elements that obscure the type. No watermark.

提示词

A photorealistic candid photograph. Scene: a sunlit kitchen, late morning, soft window light from camera-left. Subject: a six-year-old child sitting at a wooden kitchen table, reading an oversized hardcover picture book. Scale and framing: child-sized relative to the table, the book takes up about half the visible tabletop, full upper body visible. Pose and gaze: leaning slightly forward on the elbows, looking down at the open book, not at the camera; right hand turning a page, left hand resting flat on the corner of the book. Action geometry: fingers naturally curled around the page edge, no over-rendered grip. Background: a slightly out-of-focus kitchen counter with a fruit bowl. Lens look: 50mm, shallow depth of field. No glamorization, no heavy retouching. No watermark.

提示词

Create an original, non-infringing logo for a company called "Field & Flour", a local bakery. The logo should feel warm, simple, and timeless. Use clean, vector-like shapes, a strong silhouette, and balanced negative space. Favor simplicity over detail so it reads clearly at small and large sizes. Flat design, minimal strokes, no gradients unless essential. Plain background. Deliver a single centered logo with generous padding. No watermark, no trademarks, no extra text outside the brand mark.

提示词

Use the same style from the input image — same palette, brushwork, line weight, texture, and film grain — and generate a new subject: a man riding a motorcycle on a plain white background. Keep the visual style identical to the reference. Centered subject, generous padding, no extra elements, no text, no watermark.

提示词

Image 1 is the target scene: a woman standing in a museum hall under soft skylight. Image 2 is the asset to transplant: a golden retriever sitting in profile. Place the dog from Image 2 into the setting of Image 1, seated on the floor right next to the woman. Match the same style of lighting, shadow direction, color temperature, perspective, and depth of field as Image 1 so the dog looks naturally captured in the original photo. Do not change the woman, the museum hall, the camera angle, the framing, or any other element of Image 1. No watermark, no extra elements, no text.

提示词

In this room photo, replace ONLY the white chairs with chairs made of warm oak wood. Preserve the camera angle, room lighting, floor shadows, ceiling, walls, table, dishes on the table, plants, and every other object exactly as they appear. Do not alter saturation, contrast, layout, or any object that is not a white chair. Keep everything else in the image the same. Photorealistic contact shadows where the new wooden chair legs meet the floor, fabric and grain texture consistent with the existing room photography. No watermark, no on-image text.

提示词

Pass 1 (base prompt): A photorealistic still life of a single ripe tomato on a wooden cutting board, soft daylight from camera-left, 50mm lens, shallow depth of field, no watermark. Pass 2 (refinement, edit on output of Pass 1): Make the lighting warmer — shift toward golden-hour color temperature, add a subtle rim light on the right side of the tomato. Keep everything else the same: same tomato, same cutting board, same composition, same framing. Pass 3 (refinement, edit on output of Pass 2): Tighten the framing — crop in by about 20%, the tomato should fill more of the frame, cutting board still partially visible at the bottom. Do not change the lighting, color grade, or surface texture. Restate: keep the same tomato, the same cutting board grain, the same background.

提示词

Create a realistic outdoor crowd scene in Bethel, New York on August 16, 1969. Photorealistic, period-accurate clothing, staging, hairstyles, and environment. Shot like a 35mm film photograph, eye-level wide framing, natural daylight. The image should feel like a documentary photograph from the era — honest, unposed, slightly grainy, no cinematic color grading. No watermark, no on-image text, no anachronistic details.

提示词

Create one pitch-deck slide titled "Market Opportunity" that feels like a real Series A fundraising slide from a YC-backed startup. Use a clean white background, modern sans-serif typography like Inter, and a crisp, minimal layout. The slide should include: a TAM/SAM/SOM concentric-circle diagram in muted blues and grays; specific, believable market sizing numbers — TAM: $42B, SAM: $8.7B, SOM: $340M; a clean bar chart below showing market growth from 2021 to 2026 with a subtle upward trend; small footnotes "AGI Research, 2024" and "Internal analysis"; a company logo placeholder in the bottom-right corner. The design should look like it belongs in a deck that actually raised money: highly readable text, clear data hierarchy, polished spacing, professional startup-style visual language. Avoid clip art, stock photography, gradients, shadows, decorative elements, or anything that feels generic or overdesigned.
