# Image Enhance

## Overview

A simple image enhancement pipeline: sharpen for crisp details, then auto-contrast for better exposure balance.

**The Pipeline:**
1. **Image Input** (`nodetool.input.ImageInput`) - Your photo or artwork
2. **Unsharp Mask** (`lib.image.filter.UnsharpMask`) - Enhance edges and fine details
3. **Auto Contrast** (`lib.image.enhance.AutoContrast`) - Optimize brightness and contrast
4. **Image Output** - Your enhanced result

For more options: **Replicate.Image.Upscale** for AI upscaling, **Nodetool.Image.Transform** for color and brightness controls.
