This app can be used to merge photos taken at different exposures into a single high density range (HDR) image. You can then use tone mapping with various tuning options to create the final image.

The app can also be used as HDR viewer - you can view Radiance HDR (.hdr) and OpenEXR (.exr) files.

Main features include
- Debevec, Robertson, and simple "Fusion" algorithms to generate HDR image
- automatic image alignment before merging into HDR
- export generated HDR file as Radiance HDR, or OpenEXR file
- tone mapping using various algorithms (Linear mapping, Reinhard, Drago, Mantiuk)
- creating tone mapped images in multiple formats, like e.g. JPEG, PNG
