SENSOR CONFIGURATION AND FILTER SYSTEM

The ALEXA XT B+W sensor assembly has no Bayer mask, optical low-pass filter (OLPF) or IR block filter allowing each photosite to capture the full spectrum of visible light increasing spatial resolution and contrast. In this mode the camera’s look is very much like a 35 mm camera loaded with panchromatic film – the classic black-and-white look. As well as this the camera can also operate in an infrared mode in which the camera only ‘sees’ the reflected infrared non-visible light. These images appear dramatically different producing white foliage, blemish-free skin, black eye pupils, and moody dark skies. The camera is also more sensitive than a regular ALEXA XT Plus, with a native sensitivity of around EI 2000. Through the use of two new ALEXA In-Camera Filter (IFM) system compatible filters, the ALEXA XT B+W can be easily configured with either a BG39 filter to shoot stunning B+W images, or a BG87C infrared pass, visible light block filter for infrared capture.
