MoreAlbedo is used to measure the reflectance of surfaces, which is an important parameter for environmental scientists in fields like climatology, astronomy, and geoengineering.
Yes, Albedo requires the use of an 18% photographer's gray card as a reference for accurate measurements. These are widely available at photography shops and online.
Albedo uses your device's camera as a light sensor. It captures images of a gray card and the surface, then normalizes the pixel values by exposure to calculate the albedo in RGB color channels.
