Hydra 4.6.1

Hydra 4 combines a set of differently exposed photos into a single high-dynamic-range image that keeps detail in both dark and bright areas. You can aim for a natural look or push the scene toward a more dramatic result, with every adjustment previewed instantly at full resolution. It's built for photographers who shoot multiple exposures, handheld or on a tripod, and want precise control over the final image.
