Seedream 4.5 支持图像生成与参考图编辑,适合需要兼顾文字、人物和视觉风格的创作。它强调提示词遵循、文字呈现与参考人物特征保持,可以用于活动海报、角色宣传图和风格统一的系列素材。
人物创作可以从清晰参考图开始,保留面部、发型和重要服装特征,再尝试新的背景与构图。制作系列视觉时,统一主体参考、光线和色彩说明,有助于让不同场景延续同一种感觉。面部、配件和手部仍需逐张比较,尤其是在大幅改变姿态或遮挡较多时。
带中文标题的图片,可以把文案原文、位置和层级写进提示。先让主体和标题各有清楚的空间,再补充装饰,比一次塞进大量文案更容易形成可读版面。复杂字体、密集正文与品牌标识,需要在生成后认真检查。
最高 4K 输出适合较清晰的人物海报、商品视觉和设计提案。分辨率提高并不会自动纠正内容错误,正式使用前仍要检查人物身份、文字和产品细节。已有满意设计时,限定每轮改动范围,能更方便保留好的构图与气氛。
参考图提供讲者身份,保留面部特征、发型和深蓝色衬衫。制作竖版活动海报,人物位于下方偏右,背景为简洁米白色;上方标题只写“把经验讲清楚”,左下留出姓名与日期位置。自然柔光,不改变人物年龄,不增加其他文字。
确认人物后,再单独修改背景与标题位置。
人物保持要提供什么? 清晰、无遮挡、外观明确的参考图,并列出需要延续的特征。
4K 可以直接发布吗? 清晰度足够不代表细节正确,仍要检查面部、文字和标识。
系列图怎样统一? 复用人物参考与配色规则,一次改变一个场景或姿态。
