HDR Photo & Tone map - Mergius

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.
NOTE: If you think there's some issues with results the app is producing, send your sample input images with issue description directly to support email. I'll have a look it, and if I find issues, I'll certainly try to fix all of those. Don't use the review section for reporting issues - it has a strict character limit and doesn't allow structured replies and file/image attachments.

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
