Hydra (operating system) HYDRA is an early (now discontinued) capability-based, object-oriented, microkernel designed to support a wide range of possible operating systems to run on top of it. HYDRA was created as part of the C.mmp project at Carnegie-Mellon University in 1971. Hydra lets you create beautiful high-dynamic-range (HDR) images by merging multiple exposures, effectively capturing both dark and bright subjects to make it more natural, or to enhance scene drama.

HYDRA is an early (now discontinued) capability-based, object-orientedmicrokernel designed to support a wide range of possible operating systems to run on top of it.[1] HYDRA was created as part of the C.mmp project at Carnegie-Mellon University in 1971.[2]
The name is based on the ancient Greek mythological creature the hydra.
HYDRA was designed to be modular and secure, and intended to be flexible enough for easy experimentation.[3]The system was implemented in the programming language BLISS.[4]

Hydra 4.3
Hydra lets you create beautiful high-dynamic-range (HDR) images by merging multiple exposures, effectively capturing both dark and bright subjects to make it more natural or to enhance scene drama.
A single photo cannot represent the entire dynamic range of light in a scene due to the physical limitations of the sensor. The picture is either too dark or too bright, or both. Hydra allows you to overcome this limitation by merging a number of photos with different exposure settings and to create a natural image that is much closer to what your eyes actually see. Alternatively, Hydra can also artistically push contrasts to increase drama and emotions in your pictures beyond reality.
This new release of Hydra has been optimized for latest OS X enhancements and it provides native Metal support with maximum performance, in addition to a more modern and simpler user interface.
