## What it is
Brightroom is a Swift library for building composable, customizable photo editing UIs on iOS, backed by Core Image and Metal for GPU-accelerated rendering. It provides headless editing stacks that manage edit history, plus built-in components for cropping, rotating, masking, face detection, and LUT-based filters.

## Use cases
- build a custom photo editor UI in an iOS app
- crop and rotate photos with a ready-made UI
- apply LUT color filters to images
- let users draw masks on photos
- edit very large images up to 12000 pixels
- manage image editing history with undo/redo
- render images in P3 wide color gamut

## When to choose
- you need a fully customizable image editor on iOS with UIKit or SwiftUI
- you want GPU-accelerated editing of large photos
- you need headless editing state separate from the UI
- you want drop-in LUT filter support

## When to avoid
- you need an image editor for Android or cross-platform apps
- you only need simple image processing without a UI
- your project targets iOS below 15.0
- you need video or audio editing
