ABSTRACT:
A reference device for setting color biasing mechanisms on a camera and achieving a consistent color biasing in different environmental situations, and a method of making the same. The reference device comprises a reflective media having a surface that has had its spectral characteristics analyzed and its surface treated with colored droplets, wherein each of the droplets is less than 5 picoliters in volume, to achieve a degree of desired white neutrality or color bias of different spectral quality than that which was analyzed as aforesaid. A method for producing a standardized white or color-biased surface on reflective media for use with a camera with color balance setting mechanisms includes selecting a media with a surface that is suitable for modification to colorimetrically neutral reference surface, analysing the spectral characteristics of the reference surface, and treating the surface of the media with colored droplets, with each of the droplets being less than 5 picoliters in volume to achieve the degree of desired white neutrality or color bias.
