FLUX.2 提示技巧

提示框架

要获得一致的高质量结果，请使用此逻辑流构建您的提示。从左到右优先考虑元素：

主题 → 动作 → 风格 → 背景 → 次要细节

逼真风格指南

要实现真正的照片真实度，不要使用像“专业照片”这样的大众术语。相反，指定相机型号、镜头和胶片以触发特定的视觉美感。

风格	关键描述词
现代数字	“拍摄于索尼A7IV，干净锐利，高动态范围”
2000年代数码相机	“早期数码相机，轻微噪点，闪光摄影，抓拍，2000年代数码相机风格”
80年代复古	“胶片颗粒，温暖色调，柔和焦点，80年代复古照片”
模拟胶片	“拍摄于柯达Portra 400，自然颗粒，有机色彩”

多语言提示

FLUX.2不仅限于英语。为了实现最佳文化准确性，请使用目标语言进行提示。以本地语言描述场景有助于模型捕捉当地建筑和氛围的细微“氛围”，而翻译往往会忽略。

官方指南提供了广泛能力的技术规格，包括JSON结构提示、精确的颜色控制和文本呈现技巧。更多信息：FLUX.2 提示指南
