HDRView is a simple research-oriented depth-map and high-dynamic range image viewer with an emphasis on examining and comparing images, and including minimalistic tonemapping capabilities.
This is a cross-platform tool running under Linux, macOS, and Windows.
HDRView is free and open source software.
Key Features
- Supports reading EXR, PNG, TGA, BMP, HDR, JPG, GIF, PNM, PFM, and PSD images.
- Supports writing EXR, HDR, PNG, TGA, PPM, PFM, and BMP images.
- Supports loading several depth-map formats (PFM, PNG 1-channel-16bit, EXR, NPY) and convert them to RGB images for visualization
- Load several images and provides exposure and gamma/sRGB tone mapping control with high-quality dithering of HDR images
- Overlay the pixel grid and numeric color values on each pixel to facilitate inspection
- Supports high-quality dithering (both when viewing and when saving to an LDR file) to reduce artifacts caused by displaying HDR images naively on a 24 bit display.
