# Bright XDR 

__BrightXDR__ is a proof-of-concept implementation that demonstrates how to upscale display content to XDR/HDR extra brightness on macOS. This is a demo showing one of possible implementations. The display is brighter compared to Vivid.

> The main idea behind this project is to provide an open source and free-to-use alternative to existing apps that offer similar functionality for a price of up to €20. I believe that everyone should have access to powerful tools that enhance their display experience, regardless of their budget.

## About 

The app uses MetalKit to overlay the CIImage with a transparent color in EDR color space over the display windows while applying color blending filter.

## Preview 

> Screen captured on maximum system brightness with __Apple XDR (P3-1600 nits)__ display preset.
