Apparatus and techniques for enhancing blending characteristics of a composite image formed by multiple projection displays are detailed. Included among the apparatuses and techniques is the use of masks, having complimentary, non- linear edges, between a projection axis and a screen. The masks are used to solve the geometric and photometric issues involved with blending sub-images to form a composite image.
