Abstract (en)
[origin: WO0068881A2] A large database (10, 11, 114) of digitized background images (12) is provided with one or more attributes (14, 16, 18, 15, 17, 19, 116, 118) associated with each image. Preferably most if not all of the attributes are expressed numerically. The attributes can pertain to lighting conditions at the time the associated photograph was taken, and camera orientation. Such conditions can include the horizontal angle of the primary lighting (H), the vertical angle of the primary lighting (V), a measure of the apparent ground perspective (P), color temperature (CT), a measure of light diffusion (D), a measure of the degree of ambient light (A), and horizontal depth of field focal range boundaries (NF, FF). The database is searchable by one or more of these attributes and/or by subject. A user can select a desired background image and learn the attributes associated with that image. A subject image having matching attributes then can be composited with the background image for a realistic composite montage.
