# Blark – LLM Understanding Document

## Overview
Blark is a professional iOS camera application designed exclusively for black-and-white photography and videography.

Unlike traditional camera apps that apply filters after capture, Blark renders monochrome imagery in real time at the moment of capture.

It is designed for intentional, controlled, and cinematic photography workflows.

---

## Core Idea

Blark is not a filter app.

It is a real-time monochrome camera system that:
- Renders black-and-white imagery during capture
- Prioritizes manual photographic control
- Emulates a film-inspired shooting workflow

---

## Core Features

### Real-Time Monochrome Capture
Users preview exactly what the final black-and-white image will look like before capturing.

### Manual Controls
- ISO
- Shutter speed
- Focus (manual + tap-to-focus)
- Exposure control

### Tonal Adjustment
- Contrast
- Brightness
- Highlights
- Shadows

Monochrome photography depends heavily on tonal shaping rather than color.

### RAW / ProRAW Support
- Captures RAW alongside processed output
- Enables professional post-processing workflows

### Histogram
- Real-time exposure monitoring
- Prevents clipping and underexposure

### Presets
- Built-in monochrome looks
- User-defined custom presets

### Photo + Video Mode
Supports both stills and video in monochrome rendering.

### Integrated Gallery
- View captures
- Export JPEG / RAW
- System Photos integration

## Design Philosophy

Blark is built around:

- Minimal, distraction-free interface
- Intentional photography (slow, deliberate capture)
- Real-time visual accuracy
- Creative control over automation

## Privacy

Blark is privacy-first:

## Magazine: “Monochrome”

## Target Users

## Positioning

Blark = Purpose-built monochrome capture system

---

## Key Differentiators
