A day and night camera is a security camera that can see the picture during the day hours, when there is enough sunlight, and during the night in total darkness or minimum illumination. A day and night camera has special lenses that allow infrared emission produced by infrared LEDs and reflected from objects to go through and reach a CCD or ...
When shooting day for night, the scene is typically underexposed in-camera or darkened during post-production, with a blue tint added. Additional effects are often used to heighten the impression of night. As the light sensitivity of film and video cameras has improved, shooting day for night has become less common in recent years.

Light Night is an annual cultural event which first happened in the city of Leeds in October 2005, as part of the launch of the region-wide Illuminate Cultural Festival. Based on the European model of Nuit Blanche , founded in Paris in 2002, the idea of Light Night is to open cultural and other venues across the city late into the night and ...
Night photography (also called nighttime photography) is the capturing of images outdoors between dusk and dawn. Night photographers generally have a choice between using artificial lighting and using a long exposure , exposing the shot for seconds, minutes, or hours in order to capture enough light to record an image.
In fact, night vision equipment can be manufactured using one of two technologies: [4] light intensifiers or infrared vision. The former technology uses a photocathode to convert light (in the visible or near infrared portions of the electromagnetic spectrum) to electrons, amplify the signal and transform it back to photons. Infrared vision on ...
An image intensifier or image intensifier tube is a vacuum tube device for increasing the intensity of available light in an optical system to allow use under low-light conditions, such as at night, to facilitate visual imaging of low-light processes, such as fluorescence of materials in X-rays or gamma rays (X-ray image intensifier), or for conversion of non-visible light sources, such as ...
Night vision is the ability to see in low-light conditions, either naturally with scotopic vision or through a night-vision device. Night vision requires both sufficient spectral range and sufficient intensity range .
Light Labs Inc. was an American digital photography company that developed a multi-lens and multi-sensor camera designed for embedding in smartphones and mobile devices. [1] The company's first product, the L16, is a standalone version with 16 camera modules. [ 2 ]
