# Filmr

FilmeR / Film Rust

**Filmr** is a high-fidelity, physics-based film simulation engine written in Rust. Unlike simple LUT-based filters, Filmr simulates the physical properties of photographic film—from spectral sensitivity and grain structure to chemical development curves—to produce authentic, organic results.

## 🚀 Core Features

Filmr implements a comprehensive imaging pipeline that models the physical behavior of analog film:

- **🔬 Spectral Simulation**: Accurate modeling of film spectral sensitivity (Panchromatic, Orthochromatic, Infrared) using physical wavelength data.
- **🌾 Physics-Based Grain**: Spatially correlated grain synthesis based on RMS granularity and blur radius, simulating the organic texture of silver halide crystals.
- **📈 H-D Curves**: Segmented characteristic curves (D-min, D-max, Gamma) for realistic tonal response and density formation.
- **✨ Halation & Bloom**: Physical light scattering simulation (Gaussian diffusion) to recreate the signature "glow" of bright highlights on film.
- **⏱️ Reciprocity Failure**: Simulation of film speed loss during long exposures (Schwarzschild effect).
- **🎨 30+ Film Presets**: Built-in profiles for legendary stocks like Kodak Portra, Tri-X, Fujifilm Velvia, and Kodachrome.
- **📊 Diagnostic Tools**: Integrated quality verification and visualization tools for analyzing color science and signal metrics.
- **⚡ High Performance**: Parallelized image processing using `rayon` for fast rendering.

## ⚡ Quick Start

### 1. Run the GUI Demo
The interactive GUI allows you to drag-and-drop images and tweak simulation parameters in real-time.

```bash
cargo run -p filmr_app --bin filmr_ui --release
```

### 2. Generate Diagnostic Charts
Visualize the color response, grain structure, and spectral characteristics of all supported films.

```bash
cargo run --example chart_diagnosis --release
```
*Output will be saved to `diagnosis_output/contact_sheet.jpg`.*
