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.
