Amazing Photos, Beyond Sensor Limits

Thanks to innovative capture technology, Hydra lets you take beautiful pictures even in the most difficult lighting conditions. That makes it a great companion to the built-in Camera app on your iPhone or iPad.

How does it work? Hydra merges up to 60 individual images to make a single high-quality picture, effectively getting more light from the scene. That way, Hydra produces up to 32-megapixel high-resolution images (4x the 8-megapixel sensor resolution), enhanced HDR, better 2x/4x zoom, and reduced camera noise in low-light scenes.

Hydra relies on the latest evolutions of camera hardware, and uses the latest camera APIs and GPU rendering technologies of latest iOS.



More Highlights, More shadows

HDR stands for High Dynamic Range. It's a photographic technique used to reproduce a greater dynamic range of light in order to preserve details both in bright and dark areas. Just like human vision does.

Hydra offers 2 HDR modes:
  • HDR for still images by capturing and merging up to 20 images.
  • Video-HDR to capture videos with single-image tonemapping (all devices) and with device-specific sensor mode (iPhone 6 and 6 Plus only).

When taking a picture in HDR mode, Hydra automatically adjusts camera settings through bright and dark areas of the scene and it captures a number of images. Hydra then merges those images together and proposes options (intensity of the effect, black and white) to produce the final image.

Dramatically Reduced Camera Noise

Hydra is more than an HDR app though. It offers additional options to make great pictures.

Lo-Light mode, as its name suggests, is dedicated to low-light conditions, when taking pictures is particularly hazardous. In this mode, Hydra merges together multiple images to amplify light by a factor of 10. This technique significantly removes sensor noise to provide a better image quality.

Increased Resolution

Hydra uses state-of-the-art Super Resolution technique that enables recreating high-resolution images from a number of low-resolution pictures with relative motion.

This Super Resolution technique is provided in the following modes:
  • Zoom mode: recreate missing pixels from camera motion, producing 2x and 4x scale factors with more details than standard digital zooming
  • Hi-Res mode: produces up to 32-megapixel images from regular 8-megapixel camera sensor, providing finer details from the scene.
Just like for panoramic photos, it takes some time and experiments to get the right amount of camera motion that will produce the best result.

Simple and Elegant

Hydra's elegant user interface was hand-crafted with a focus on simplicity, in order to give the best possible user experience.

Hydra also features a photo gallery, for reviewing images and their metadata, that is directly linked with the built-in photo album. This helps avoiding duplicates by deleting photos, and allows to flag photos as favorites. All of this without leaving Hydra.
