My name is Leon, I am a commercial photographer. And I built a camera app for IOS. Why? My camera bag weighs around 20kg (44lbs) And film (which I also love, costs around 60$ per roll(36 images). Which includes the roll, development and extremely low res scan. I have tried so many camera apps (including the built in one) But it either was too flat and boring, and needed editing. Or it was applying filters and it still wasn’t that good. And all I wanted is a good “point and s
痛点：胶片摄影成本极高（约60美元/卷36张）且器材沉重，现有手机相机App要么画面平淡需要后期，要么滤镜效果差，用户只想要一台“拿起就拍、直出即可用”的胶片质感相机。
目标用户：喜欢胶片质感但不愿承担胶片成本的手机摄影爱好者、摄影从业者、日常随手拍的普通用户
证据：film (which I also love, costs around 60$ per roll(36 images)) ... I have tried so many camera apps (including the built in one) But it either was too flat and boring, and needed editing.

变现：App Store付费下载（$4.99–$9.99买断）＋胶片LUT风格包内购（$1.99/套）＋订阅解锁全部风格与Pro手动控制
MVP：两周MVP：用Claude Code快速开发iOS单页相机，内置5–8个手工调校的胶片LUT，核心是实时预览＋一键快门直出无水印，先不做相册管理、社交和编辑功能，先上TestFlight收集20位摄影爱好者的直出样片反馈。
竞品：VSCO、Dazz Cam、Reeze、Halide、Filmbox、Mood Camera、Gudak Cam
摘要：商业摄影师Leon因胶片成本约60美元/卷36张、装备重达20kg，自己用Claude Code做出iOS相机App Citus Camera，主打从真实胶片Stock反推的LUT与实时预览直出。这是竞品发布贴而非需求验证，帖子既无收入数据也无他人付费附和，但“免后期直出胶片感”的需求已被VSCO、Dazz Cam等大量产品验证，属于竞争激烈、独立开发者易做但难差异化的红海赛道。
