- Lighting and camera settings records all the parameters that were varied during image acquisition. Note that these include some combinations that are inappropriate, such as setting the camera white balance to D65 with an A scene illuminant to produce off-colour images. This was done in order to challenge the calibration algorithm. 1st Illuminant D65: 'Artificial Daylight' fluorescent lamps conforming to Standard Illuminant D6500 (6500 K), 2nd Illuminant TL84: Philips Triphosphor fluorescent lamps, often chosen as a 'Point of Sale' illuminant, (5200 K), 3rd Illuminant A: 'Filament (domestic) lighting' (3000 K). In digital photography, ISO measures the sensitivity of the image sensor. Exposure is measured in lux seconds, and can be computed from exposure value (EV) and scene luminance over a specified area. White balancing is a feature that allows to compensate for different lighting conditions by adjusting the color balance based on the difference between a white object in the image and a reference white.
