# RawLab
English | 简体中文
Cross-brand RAW development and film looks, built around a shared C++ processing
core with native Windows, macOS, Android and iOS editors.
## Overview
RawLab develops camera RAW files, applies compatible Fujifilm film-simulation
LUTs and custom looks, and exports finished photographs without changing the
original files. It is an independent project, not an official Fujifilm product;
film looks do not promise an exact match to in-camera JPEGs.
## Features
- RAW development with exposure, camera-space white balance, tone, color and
 sharpening controls.
- Ordinary opaque RGB8 SDR images: JPEG/PNG
 on all four clients, TIFF on macOS/iOS/Windows and HEIF on macOS/iOS. Raster
 input shares the editing/export core without the RAW scene curve or camera
 controls. Unsupported HDR, high-bit-depth, transparent and multi-frame inputs
 are rejected rather than silently converted. See the
 input contract.
- New RAW edits start with embedded-preview exposure matching. One-shot Auto
 exposure and an eight-channel HSL mixer are shared across all four clients;
 existing saved exposure baselines are preserved.
- Built-in film looks with 0-200% strength, compatible CUBE/RLOOK imports and
 neutral-versus-edited comparison.
- Fourteen master recipes with style artwork and matching controls across all
 clients. Applying a recipe replaces six adjustments and all 24 HSL values;
 0-200% strength scales the current recipe controls, HSL and LUT together.
 Saved edits and frozen batches preserve manual changes and per-target RAW WB.
- Drag-only mobile film/recipe lists and desktop overflow buttons, plus adaptive
 iPad portrait/landscape layouts. iOS adjustment ranges, steps and highlight
 direction match macOS without changing older saved rendering values.
- Linear-light wavelet denoising with separate luma, chroma and coarse-chroma
 controls, plus matching vignette and deterministic grain on all four clients.
 Metal, GLES 3.1 and D3D11 accelerate the shared denoising and effects kernels.
- Per-photo local edit memory and resumable batch export with frozen settings,
 cancellation and failed-item retry, without modifying RAW files.
- Photo information overlays, zoom/pan and original-size or long-edge exports.
 Desktop file browsers can reveal photos and apply confirmed current settings.
- JPEG and 16-bit PNG export on Windows, macOS and Android; JPEG export on iOS.
 Rendered DNG file export is available in single and batch workflows on all four
 clients. It bakes the current adjustments, not reversible sensor RAW controls.
 See the rendered DNG contract and limits.
 Readable capture metadata is retained, while output size and orientation are
 updated.
- Metal, Direct3D 11 and OpenGL ES processing where supported, with automatic CPU
 fallback. HSL runs in the platform photo GPU pipeline; RAW decoding and file
 encoding remain CPU operations.
- A shared C++17 core, command-line tools and a desktop LUT preparation utility.
- Desktop Agent JSON editing, c
