Abstract

An exposure system for creating a single frame transparency having an enlarger rack with a transparency fixture. The fixture includes an inner and outer frame which cooperate to allow incremental relative movement therebetween during an exposure process which results in a single transparency having four independent images, each of the images having spaced apart groups of pixels interlaced with the groups of pixels from each of the other images, each of the images being selectable for projection by a movable grid mask. A method for preparing four images from a single transparency is also disclosed. The transparency is formed by sequentially exposing portions of a sheet of film overlayed by a gridlike mask, and correspondingly repositioning the mask after each exposure such that a new interlaced area of film is exposed.
