Features & Capabilities

HDR Photo & Tone map - Mergius is an Android app that merges photos taken at different exposures into a single high dynamic range (HDR) image. Users can then apply tone mapping with a variety of tuning options to produce the final picture. The app supports Debevec, Robertson, and simple "Fusion" merging algorithms, focus stacking, and automatic image alignment before merging.

Tone mapping is available through Linear mapping, Reinhard, Drago, and Mantiuk algorithms. Finished images can be exported as JPEG or PNG, while generated HDR files can be saved as Radiance HDR or OpenEXR. The app also works as an HDR viewer for Radiance HDR (.hdr) and OpenEXR (.exr) files.

User Reviews

Unfortunately the app did not perform well in producing a proper HDR image from the inputs, with the resulting image having strange coloration, plus the vast majority of features are locked behind a paid subscription, so won't be able to try much unless you pay first.
