用模块化提示工程在安全过滤下生成艺术人体摄影
FIGURA: A Modular Prompt Engineering Method for Artistic Figure Photography in Safety-Filtered Text-to-Image Models
- 构建8个知识模块的提示系统,利用艺术引用和空间语境绕过过滤
- 在FLUX 2 Pro上实现80%~90%成功率,验证方法有效性
- 适合专业摄影师在商用模型中生成合规艺术人像
商业文本到图像(T2I)模型中的安全过滤机制会将经典人体摄影与色情内容一视同仁地屏蔽。尽管已有研究广泛记录该问题,但尚无有效系统支持艺术家在开启安全过滤的情况下生成艺术性人体照片。本文提出FIGURA方法(用于生成无限制艺术成果的框架),由八个相互关联的知识文件组成,在启用默认安全阈值的FLUX 2 Pro(云版)上通过200多次测试进行实证验证。系统测试揭示四个此前未被发现的关键发现:(1) 安全过滤主要识别‘缺失描述’(如衣物缺失),而非‘存在描述’(身体形态),我们将其归纳为“黄金法则”;(2) 艺术家名称作为审美引导与安全锚点双重作用,可改变过滤行为;(3) 空间上下文是独立的过滤变量,具有明确的成功率层级;(4) 几何词汇描述身体可在轮廓情境下绕过模式识别。该系统在五个结构化提示模板中实现80%至90%的文档化成功率,证明艺术审查问题可通过与安全机制共存的方式系统性解决。
原文摘要 · Abstract (English)
Safety filters in commercial text-to-image (T2I) models systematically block legitimate artistic content involving the human figure, treating classical nude photography with the same restrictiveness as explicit material. While prior research has documented this problem extensively, no operational system exists that enables professional artists to generate artistic figure photography within the constraints of active safety filters. We present the FIGURA Method (Framework for Intelligent Generation of Unrestricted Artistic Results), a modular prompt engineering system comprising eight interconnected knowledge files, empirically validated through 200+ documented generation tests on FLUX 2 Pro (Cloud) with active safety filters at the default tolerance level. Our systematic testing reveals several previously undocumented findings: (1) safety filters primarily detect absence descriptions (references to missing clothing) rather than presence descriptions (references to body form), which we formalize as the Golden Rule; (2) artistic references to painters function simultaneously as aesthetic guides and as safety anchors that alter filter behavior; (3) spatial context operates as an independent filter variable, with documented success rate hierarchies; and (4) geometric vocabulary for body description bypasses pattern recognition in silhouette contexts. The system achieves documented success rates between 80% and 90% across five structured prompt templates, demonstrating that the artistic censorship problem identified in recent literature admits practical, systematic solutions that work with active safety mechanisms rather than circumventing them.
