胶感 vs 一卷 Rollbook

胶片的质感，不应该只属于胶卷。 xcamera 是一款专为热爱胶片美学的人设计的相机应用。它不追求繁杂的参数，只给你四种真正好看的胶片风格，开箱即拍，张张成片。 ■ 四种胶片风格 STD — 标准 以 Kodak Portra 400 与徕卡 M 的搭配为参照。奶油色的高光、微暖的阴影、克制的对比——是那种"随手拍出来也不像手机照片"的温度。 VIV — 鲜艳 以 Kodak Ektar 100 为灵感。饱和、深沉、有颜色主张。绿色是真正的绿，蓝色是真正的蓝，暖色里有一种德国工业的厚重感。 NAT — 自然 好冲洗的 C-41 胶片的直出样子。几乎没有色彩偏转，只是让照片多一点空气感和温度，让它不那么"数码"。 BW — 黑白 参照徕卡 M Monochrom 的全色感光特性。不是简单去饱和，而是有层次的灰——高光是奶白而不是粉笔白，阴影有细节而不是死黑。 ■ 每种风格背后 每张照片都经过完整的色彩流水线处理：3D LUT 主导色彩基调，精细的曝光与 Gamma 微调，胶片颗粒（暗部重、亮部轻，有彩色颗粒感），以及高光卤化银晕染（Halation）。这些效果只在保存成片时完整渲染，不影响取景流畅度。 ■ 简洁的拍摄体验 点击取景器任意位置即可精确对焦与测光。快门按下，即时保存。没有多余按钮，没有干扰操作。 ■ 独立图库 所有照片保存在 App 内，随时查看、筛选、导出。每张照片都记录拍摄时选用的胶片风格。 --- 相机只是工具。 我们在意的，是你按下快门那一刻，照片该有的样子。 Film grain. Film tones. No film required. xcamera is a camera app for people who love the look of film — but want the speed and convenience of a phone. No complex sliders. Just four beautiful presets, ready to shoot. ■ Four Film Presets STD — Standard Inspired by Kodak Portra 400 through a Leica M. Creamy highlights, subtly warm shadows, restrained contrast. The kind of shot that doesn't look like it came from a phone. VIV — Vivid Inspired by Kodak Ektar 100. Saturated, dense, opinionated color. Greens that are actually green. Blues with depth. Warmth that feels earned, not filtered. NAT — Natural The clean, straight-developed look of a good C-41 roll. Minimal color shift, just a touch of warmth and air — enough to feel like film without feeling like a filter. BW — Black & White Modeled after the Leica M Monochrom's panchromatic sensor response. Not just desaturated — tonal. Creamy highlights that never clip to chalk. Shadows with detail. ■ Under the Hood Each photo passes through a full color pipeline: a 3D LUT sets the tone, exposure and gamma are fine-tuned per preset, film grain is weighted toward shadows (colorful, not digital), and halation softens bright edges the way silver halide would. These effects render fully on capture — not in the viewfinder, where you need the frames. ■ Simple to Shoot Tap anywhere to focus and meter. Press the shutter. Done. No menus between you and the moment. ■ Your Own Roll Photos stay in-app, organized by when you shot them. Filter by preset. Export when you're ready. --- The camera is just a tool. What matters is what the photo looks like when you're done.
