The general optical composition equipment is unable to meet the requivements of Largesizd colour composition of satellite image. So a composition box

with an enlarger

has been developed for large-sized colour composition.This report introduces the principle of development and operation of transnit adjustment box

composition methods

points for attention and the experiences that we gained in the making of image with various sensitive material.As a result of the development of remote sensing technique

we now have various simple and convenient composition methods. The method that we introduce here is one of them.
