如何使用 ChatGPT Image 2

要使用 ChatGPT Image 2，先选择合适的工作流，写清提示词，必要时上传参考图，选择输出设置，生成第一版结果，然后一次只优化一个细节，直到图片达到可用状态。

ChatGPT Image 2 分步骤使用指南

步骤 1

Choose the right image workflow

Start by deciding whether you need text-to-image generation, image editing, image-to-image variations, background replacement, product photo cleanup, or upscaling.

步骤 2

Write the main subject first

Begin your ChatGPT Image 2 prompt with the person, product, scene, object, or layout that must remain central in the result.

步骤 3

Add style, composition, and lighting

Describe the format, camera angle, crop, background, color palette, and lighting so GPT Image 2 understands the visual direction.

步骤 4

Include exact text for labels or posters

When you need readable text in an image, quote the exact headline, label, UI copy, or poster words and keep them short.

步骤 5

Upload reference images when consistency matters

Use reference images for product identity, face consistency, character design, style matching, pose control, or image-to-image transformations.

步骤 6

Choose aspect ratio and output quality

Pick square for social posts, portrait for vertical ads, landscape for hero images, and higher quality when the export will be used in campaigns or product pages.

步骤 7

Generate a first draft

Aim for a usable first version instead of solving every detail in one prompt. Review subject accuracy, text, background, lighting, hands, labels, and layout.

步骤 8

Refine one detail at a time

Improve the image with focused follow-up prompts such as brighter lighting, cleaner background, sharper label, tighter crop, different color, or more realistic shadows.

步骤 9

Download, upscale, or keep iterating

Export when the result is ready, upscale if you need sharper detail, or keep iterating with more specific instructions for commercial-ready output.

步骤 10

选择合适的图片工作流

先判断你需要文生图、图片编辑、图生图变体、背景替换、商品图清理，还是图片放大。

步骤 11

先写清主要主体

在 ChatGPT Image 2 提示词开头先说明人物、产品、场景、物体或版式，让模型知道画面核心是什么。

步骤 12

补充风格、构图和光线

描述图片格式、镜头角度、裁切、背景、色彩和灯光，让 GPT Image 2 理解整体视觉方向。

步骤 13

需要文字时写出精确文案

如果要生成标签、海报或 UI 里的可读文字，把标题、标签或按钮文案用引号写出来，并尽量保持简短。

步骤 14

需要一致性时上传参考图

当你要保持产品身份、人脸一致、角色设计、风格匹配、姿势控制或图生图效果时，使用参考图会更稳。

步骤 15

选择比例和输出质量

社媒图适合方图，竖版广告适合 portrait，首屏 hero 图适合横图；如果要用于广告或商品页，可以选择更高质量。

步骤 16

先生成一版初稿

第一轮先追求可用初稿，不要一次解决所有细节。检查主体、文字、背景、光线、手部、标签和构图。

步骤 17

一次只优化一个细节

用后续提示词逐步改进，比如让光线更亮、背景更干净、标签更清晰、裁切更紧、颜色不同或阴影更真实。

步骤 18

下载、放大或继续迭代

结果可用时直接导出；如果需要更清晰的细节，可以放大；如果还要商用成片，就继续用更具体的指令迭代。

给新手的提示

  • Use ChatGPT Image 2 prompts that name the subject, style, composition, lighting, colors, and final use case.
  • For product photos, say what must stay unchanged: shape, label, logo, material, color, and realistic shadow.
  • For image editing, describe both what to preserve and what to change.
  • For image-to-image prompts, upload a clear reference image and explain the target style or scene.
  • For posters and labels, quote exact text and keep the words short enough to render clearly.
  • Choose the aspect ratio before generating so the composition fits the final placement.
  • Generate a broad first draft, then refine with one change per follow-up prompt.
  • Use higher quality or upscaling for ecommerce images, landing page heroes, ads, and final campaign assets.
  • ChatGPT Image 2 提示词最好同时包含主体、风格、构图、光线、色彩和最终用途。
  • 做商品图时，明确说明哪些部分不能变：形状、标签、Logo、材质、颜色和真实阴影。
  • 做图片编辑时，同时写清要保留什么、要修改什么。
  • 做图生图时，上传清晰参考图，并说明目标风格或目标场景。
  • 做海报和标签时，把精确文字放在引号里，并让画面文字保持简短。
  • 生成前先选好比例，避免最后构图不适合投放位置。
  • 先生成大方向，再用每次一个修改点的方式继续优化。
  • 电商图、落地页 hero 图、广告图和最终活动素材，建议使用更高质量或放大工作流。

常见错误

  • Writing vague prompts such as make it better without naming the desired change.
  • Mixing too many subjects, styles, and camera directions in one request.
  • Forgetting to tell GPT Image 2 which product details, faces, labels, or layout elements must be preserved.
  • Asking for long paragraphs of text inside an image instead of short quoted words.
  • Skipping reference images when brand consistency or character consistency matters.
  • Choosing the wrong aspect ratio for a thumbnail, product listing, ad, or hero image.
  • Regenerating from scratch when a small follow-up edit would fix the result faster.
  • Exporting before checking text accuracy, hands, shadows, labels, background edges, and composition.
  • 只写“变好看一点”这类模糊提示，却没有说明想改哪里。
  • 在同一条提示词里混入太多主体、风格和镜头方向。
  • 忘记告诉 GPT Image 2 哪些产品细节、人脸、标签或版式必须保留。
  • 要求图片里出现很长的段落文字，而不是简短可读的引号文本。
  • 需要品牌一致性或角色一致性时没有上传参考图。
  • 没有根据缩略图、商品列表、广告或 hero 图选择合适比例。
  • 明明只差一个小修改，却重新生成整张图。
  • 导出前没有检查文字、手部、阴影、标签、背景边缘和整体构图。

FAQ

How do I use ChatGPT Image 2 for the first time?

Start with the AI Image Generator if you want a new image from text. Write a prompt that explains the subject, style, composition, lighting, and final use case, then generate a first draft and refine it.

Can I edit an existing image with GPT Image 2?

Yes. Use the image editor, upload the image, say what should stay unchanged, and describe the exact edit such as background replacement, relighting, cleanup, color change, or sharper product detail.

When should I upload a reference image?

Upload a reference image when consistency matters for a product, face, character, logo, pose, room layout, style direction, or image-to-image variation.

What should a ChatGPT Image 2 prompt include?

A practical prompt includes subject, style, composition, camera angle, background, lighting, color palette, exact text if needed, and the intended use of the final image.

How do I get better product photos?

Describe the product clearly, preserve label and packaging details, request realistic shadows, specify the background, and use a reference image if the product identity must stay exact.

How do I make text more readable in generated images?

Keep embedded text short, put the exact words in quotation marks, ask for clean typography, and avoid asking for long paragraphs inside the image.

Should I regenerate or refine a result?

Refine when the image is close and only one detail is wrong. Regenerate when the subject, layout, or overall art direction is far from the brief.

Which output quality should I choose?

Use standard output for drafts and quick prompt testing. Use higher quality or upscaling for product images, ads, hero visuals, thumbnails, and campaign assets that need sharper detail.

第一次如何使用 ChatGPT Image 2？

如果你想从文字生成新图片，先打开 AI 图片生成器。写清主体、风格、构图、光线和最终用途，生成第一版后再继续细化。

GPT Image 2 可以编辑已有图片吗？

可以。打开图片编辑器，上传图片，说明哪些内容要保留，再写清具体修改，比如换背景、补光、清理杂物、改颜色或增强商品细节。

什么时候应该上传参考图？

当你需要保持产品、人脸、角色、Logo、姿势、房间结构、风格方向或图生图变体的一致性时，就应该上传参考图。

ChatGPT Image 2 提示词应该包含什么？

实用提示词通常包含主体、风格、构图、镜头角度、背景、光线、色彩，需要时加精确文字，并说明最终用途。

如何生成更好的商品图？

明确描述产品，保留标签和包装细节，要求真实阴影，指定背景。如果产品身份不能变，最好上传参考图。

如何让图片里的文字更清晰？

把文字写短，用引号标出精确文案，要求干净字体，并说明文字出现在画面的哪个位置。

应该重新生成还是继续细化？

如果图片整体接近目标，只是某个细节不对，继续细化更快。如果主体、布局或整体方向都错了，再重新生成。

应该选择什么输出质量？

草稿和提示词测试可以用标准输出；商品图、广告、hero 图、缩略图和活动素材建议使用更高质量或放大。
