RAW Stacking & AI Denoise

Reveal morefrom every frame.

Your camera captures the frames. Your iPhone or iPad stacks them. Transfer your photos, align and combine them, then refine and export your result — without a computer.

释放每一帧隐藏的细节

用相机拍摄,用 iPhone 或 iPad 完成堆栈。传入照片后,在设备上对齐、合成、调色并导出;外出拍摄,也不必带电脑处理。

Available now on the App Store for iPhone and iPad 现已在 App Store 上架,支持 iPhone 与 iPad

Real photographs. Documented processing.

真实照片,说明处理过程

One night sky.
Six RAW frames.

同一片星空,
六张 RAW 合成。

A real Sony RAW sequence photographed by the developer. Compare one exposure with the app's six-frame stack, then watch the 15-second silent walkthrough.

开发者实际拍摄的 Sony RAW 序列。对照一张曝光与 App 六帧堆栈的结果,再通过 15 秒无声演示了解流程。

Single frame → six-frame stack 单张原片 → 六帧堆栈 Tap to inspect the presentation image. Noise reduction also involves a detail trade-off; this is one example, not a guarantee for every scene. 点击查看展示图。降噪与细节保留存在取舍;这是一组真实样例,并不保证所有场景都有相同效果。
Understand it without sound 不用声音,也能看懂 A condensed before/after demonstration with on-screen labels. The 15-second video is not a real-time processing benchmark. 带画面标注的前后对比短片。15 秒是演示片长度,不代表实际处理耗时。

这组对比如何制作

Reference: Sony _DSC7605.ARW. Result: the app's recorded six-frame Milky Way stack. The images and video were prepared in August 2026 with crops, labels and presentation resizing only — no generated stars, replaced sky or additional promotional denoising. The 1080 × 1350 presentation is not the source RAW resolution or a full-resolution export benchmark. Star motion and the fixed foreground require different alignment; inspect both rather than judging only smoothness.

参考帧为 Sony _DSC7605.ARW,结果来自已留存的 App 六帧银河堆栈。图与视频制作于 2026 年 8 月,仅作裁切、标注和展示缩放,没有生成星点、替换天空或额外宣传降噪。1080 × 1350 是展示尺寸,不是 RAW 原片分辨率,也不是满分辨率导出测试。星空运动与固定地景的对齐方式不同,请同时检查两者,而不只看画面是否平滑。

iOS / iPadOS 17 or later. AI features require iOS / iPadOS 18 and a compatible device. RAW decoding and automatic lens matching depend on the camera, file metadata and operating system. The App Store shows your local price. 需要 iOS / iPadOS 17 或更高版本;AI 功能需要 iOS / iPadOS 18 及兼容设备。RAW 解码与自动镜头匹配取决于相机、文件元数据和系统支持。当地售价以 App Store 为准。

A complete mobile workflow

完整的移动摄影工作流

From difficult frames to a finished image.

从复杂原片,
到完整作品。

Built for night scenes, Milky Way shots, light trails, flowing water, cleanup, and everyday landscape photography.

01

RAW-first import

RAW 优先导入

Work with supported camera RAW formats and standard photos while preserving the originals. Matching profiles can correct geometric lens distortion; automatic vignetting and chromatic-aberration correction are not currently included.

导入受支持的相机 RAW 与标准照片,不修改原始文件。配置匹配时可校正镜头几何畸变;目前不包含自动暗角和色差校正。

02

Intelligent stacking

智能照片堆栈

Align and combine frames for cleaner detail, smoother motion, light trails, or unwanted-object cleanup.

自动对齐并合成多帧,用于降噪、柔化运动、光轨与画面清理。

03

On-device AI denoise

设备端 AI 降噪

NAFNet-based enhancement reduces visible noise locally, with a non-AI fallback when needed.

基于 NAFNet 的增强在本地减少噪点,并在需要时自动使用非 AI 方案。

04

AI super-resolution

AI 超分辨率

Real-ESRGAN 4× enhancement can recover perceived detail for compatible images and devices.

Real-ESRGAN 4× 增强可在兼容图像和设备上提升观感细节。

05

Precise finishing tools

精细调色工具

Adjust exposure, tone, color, clarity, sharpening, noise reduction, and crop in one focused workflow.

在统一工作流中调整曝光、影调、色彩、清晰度、锐化、降噪与裁切。

06

High-quality export

高质量导出

Export JPEG, PNG, 16-bit TIFF, or 10-bit HEIF with sRGB, Display P3, Adobe RGB, or preserved color.

导出 JPEG、PNG、16 位 TIFF 或 10 位 HEIF,并支持多种色彩空间。
