Number: 355/52
Name: Photocopying > Projection printing and copying cameras > Distortion introducing or rectifying
Description: Subject matter including means to distort the image transferred to the photosensitive paper, such as magnifying or reducing the image in one direction more than in the other, or including means to correct or compensate for distortion present in the original which is to be copied, such as when the original was taken from an airplane which was at an angle to the earth.
