Full description
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

What's new

- Added deghosting option - Made some more significant changes in how "Fusion" mode works, and allowed to apply post processing effects - Moved the output format and resolution selection at a later stage, so that it's possible to export/save different formats, resolution, post processing effects faster - Some minor UI/UX improvements - Upgraded to target SDK 36
