About Doubao Seedream 4.0 250828

Seedream 4.0 适合把图片生成和编辑放在同一个创作过程中。可以先用文字探索构图,再上传参考图约束商品或人物,继续调整场景与风格。中文营销素材、产品设计草图和角色系列图,都可以用这种方式逐步推进。

系列图片是它很实用的方向:同一个角色换不同场景,同一件商品尝试不同拍摄环境,或围绕同一套色彩建立连续视觉。保持主体参考与风格说明一致,再改变少量内容,能更容易看出每张图之间的联系。角色、商品与服装的细节仍要逐张检查,不能只凭整体配色相似就判断一致。

文字创作时,先确定主体、位置与光线,再安排标题和留白。编辑时,写清要改变的部分和必须保留的结构,避免一次同时替换背景、主体和版式。中文短标题可以融入画面,长正文、复杂图表和精细标识适合后期检查与排版。

最高 4K 输出可用于较清晰的展示素材。对于真实商品或人物形象,优先提供准确参考,再查看比例、连接处、面部与文字。先挑出一张主体和构图都合适的图片,再延伸系列,能减少不同版本之间的细节漂移。

Use cases and prompting

为儿童绘本角色做场景图

参考图中的小熊是固定角色,保留圆耳朵、黄色围巾和棕色毛色。小熊坐在草地上读一本红色书,旁边只有一朵小花。柔和水彩插画,浅绿与暖黄色调,画面简洁,不添加文字或其他角色。

下一张只把场景改成窗边阅读,持续使用同一角色参考与配色说明。

系列图怎样开始? 先确定一张满意的角色设定,再复用它扩展不同场景。

多图输出等于细节完全一致吗? 仍需比较面部、服装和配件,必要时单独修正。

带中文标题的图要注意什么? 准确提供短文案和位置,生成后逐字检查,长正文留给排版。
