About GPT Image 2.5 Sunburst

当一张图片已经接近完成,修改的难点就变成了“动这一处,其他地方尽量留下”。GPT Image 2.5 Sunburst 偏重画面质量、细节保持和复杂指令执行,适合有明确交付要求的图像生成与编辑:商品的轮廓要对,人物的特征要延续,标题要出现在指定位置,背景又要与主体协调。

精修已有画面

你可以上传参考图,把修改范围讲清楚。例如保留皮包的包型、缝线和五金,仅改变拍摄背景;保留人物面部与服装,把画面扩展成更适合横版封面的构图。对于需要同时照顾主体、材质、光线和构图的任务,Sunburst 能帮助把零散的要求组织到同一张图里。细小文字、品牌标识和真实商品细节,仍要与原图对照检查。

把文案和视觉一起安排

制作活动海报或商品宣传图时,可以指定标题原文、字号层级、画面重心和留白区域,而不是先做一张好看但放不下文字的图片。对已经满意的设计,后续修改最好明确限定要变动的内容,减少连续重绘带来的细节漂移。

模型支持文字与图像输入、不同质量档位和透明背景输出,既能从概念开始创作,也能继续精修现有素材。透明素材适合电商陈列、页面装饰和设计拼贴;较复杂的反射、玻璃边缘和阴影,需要放到实际背景中确认效果。对于只想快速筛选多个方向的工作,可以先用 Flare 试构图,再用 Sunburst 认真打磨最终方案。

Use cases and prompting

保留包型,重做品牌主视觉

以参考图中的棕色皮包为主体,保持包型、提手比例、缝线位置和金属扣件。只把背景改成暖灰色摄影棚,使用柔和侧光,皮包位于横版画面右侧,左侧留出干净空间。不要添加装饰挂件,不改变现有标识,不生成任何文字。

确认商品细节后,再单独提出标题需求,例如左侧只写“日常,刚刚好”,保持产品与构图不变。

怎样说明局部修改? 把“只改背景”和必须保留的轮廓、材质、配件分别说清楚,并提供清晰原图。

适合修图还是重新生成? 两者都可以;当原图已有满意主体时,先做限定范围的修改,更容易比较前后差异。

可以保证商品完全不变吗? 生成编辑仍可能改变细节,正式使用前应检查标识、五金和比例。
