Have you ever wanted to take a photo in low light conditions? Due to complex mathematical algorithms Night Eyes provides residual light amplification in real-time for your iPhone, iPad and iPod touch without additional hardware. The image is illuminated in real-time (without delay). You can also switch the light amplification mode to exposure mode for better quality. With an exposure time of up to one second you will be able to view the smallest details. It's ideal for twilight situations. The luminance histogram shows you the brightness level in real-time. Zoom in inconspicuously using the 10x digital Live Zoom - and shoot your photos. You've naturally got many different color filters to choose from. The most important functions are: - Three amplification modes - Up to 1 second * exposure time - Residual light amplification - True low light enhancement - Real-time luminance histogram - Volume Up (+) Photo Capture - 10x digital live zoom - Tap to focus - Color filters: green, red, blue, b/w, sepia, etc. - Take HD photos - Landscape and portrait modes - Supports the front & back cameras - Supports LED lights - Supports EXIF-data *) only on supported devices A good camera and a powerful processor are required, to get the maximum picture quality. All the screenshots listed were taken with an iPhone and iPad and are genuine! Please note that this app does not provide true night vision functionality. The iPhone, iPad and iPod touch have no infrared amplifier, as a result no pictures can be taken in total darkness; a minimal level of light is still required, which can be ascertained by the camera's sensors. The preview will also be delayed in exposure mode. In addition the camera must be held stable for exposure time. ---------------------------- Follow us: http://twitter.com/CLIDOapps Visit us: http://www.clidoapps.com - Subscription Terms: https://www.clidoapps.com/app/iap/ios/nighteyes Privacy Policy: https://www.clidoapps.com/app/privacy/ios/nighteyes Terms and Conditions: https://www.clidoapps.com/app/tac/ios/nighteyes
