Orasis

Orasis is a 1-shot HDR app. It takes a SINGLE image and automatically transforms it to a well-exposed, natural-looking photo, simulating the way your eyes perceived the scenery at the moment the photo was taken.
Based on a decade of academic research, Orasis uses a proprietary image processing algorithm: dark and bright image regions are enhanced, revealing information that was not visible previously. More importantly though, well-exposed areas are not affected! To the best of our knowledge this is a unique feature not offered by any other app in the industry.
Orasis is the FREE version of OrasisHD. Compared to the HD version, it offers limited high resolution saves/shares (15) and it displays advertisements after each save. If you want always high resolution saving/sharing without advertisements, please consider purchasing OrasisHD.
