一台相机，一卷日常。 有些瞬间，值得多看一眼，再按下快门。 EMULSION 是一款以胶片摄影流程为灵感的影像工具。在这里，照片不只是套上一个滤镜：你可以选择相机与胶卷，体验不同画幅的构图，拍摄、回卷、走进暗房，再把完成的作品按卷收藏。让每一次拍摄，都有开始，也有回看的余韵。 【从喜欢的相机开始】 在相机仓库中挑选自己的拍摄伙伴，搭配不同镜头与胶卷。135、120、110 与 SUPER 8，各有不同的画幅与影像趣味；标准画幅、半格和宽幅，让细碎日常与开阔风景都有合适的位置。 【让一卷照片拥有自己的影调】 彩色负片、黑白与反转片，以不同的色彩、反差和颗粒呈现同一个世界。通过样片与滑动对比，找到更适合眼前场景的胶卷，而不是只凭名字选择。 【把暗房，也变成创作的一部分】 选择自动或手动冲洗，体验照片逐渐呈现的过程。保留胶片边框时，可选择显示胶卷型号与编号，让画面之外，也留下这一卷的身份。 【已有的照片，也值得重新构图】 从手机导入横向或纵向照片，拖动、缩放，选择完整显示或填满画面，细调你真正想留下的部分。旋转照片时，信息文字保持正向；冲洗时间、药水、地点，以及头像与名字，都可以按需显示。 【按卷收藏，慢慢回看】 在照片库中整理作品，查看、分享与导出。胶卷不只是拍摄时的选择，也是一段日常的归档方式。 【保留一点拍照之外的乐趣】 在离线音乐库里挑一张唱片，用 Apple Watch 遥控快门。首次进入主要页面时，教程会逐个高亮真实按钮；需要时，也能在设置中重新观看。 核心影像处理在本机完成，作品保存在本机，无需创建账号。App 内金币为本地功能计数，不可购买、转让或兑换现金。 愿每一卷，都有值得被留下的光。
