Hydra
Hydra is a Mac HDR photo editor for merging bracketed exposures and adjusting tone, detail, and color in high-contrast images.
What is Hydra?
Hydra is a native Mac photo editing app for creating high dynamic range images from one or more photos with different exposures. It is designed for photographers who want to recover shadow and highlight detail, balance difficult lighting, or create a more dramatic look from landscape, architecture, interior, and travel shots. The app combines multiple exposures into a single HDR image and provides controls for tone mapping, brightness, contrast, saturation, and other finishing adjustments. It also includes tools for aligning source images and reducing ghosting caused by movement between shots. Hydra is published by Creaceed SRL and fits naturally into Mac photography workflows for importing, editing, and exporting finished images.

Safety overview
Status: Safe
Hydra is a legitimate photo-editing application for macOS. Access to your pictures and photo library is normal for its purpose, and any edits or exports affect only the images you choose to work with. As with any editor, keep originals if you want to preserve an untouched version of your source photos.
Recommendation: Keep Hydra if you use it for HDR photography or advanced exposure blending on your Mac. If you no longer edit photos with it, you can remove the app and its support files to recover space without affecting macOS itself.
