4、 of letters and numerals in this standard are with respect to 35-mm motion-picture film and are modified proportionally in accordance with SMPTE RP 65 for 70-mm and 16-mm prints . 4.2 Information appearing in the leader which is printed lengthwise (in the direction of film travel) shall read from le

5、ft to right when viewed from the projection lens towards the projector light source with the head end of the film at the right. Information appearing in the leader which is printed upright shall read normally when the reel is uppermost and the head of the film hangs down ready for threading (see fig
