ORWO Negative Film NP 3
Table of Contents
The NP 3 is a very fine-grain recording material of medium sensitivity for outdoor recordings. The remarkable sharpness of contours and the high resolving power offer favorable conditions, e.g. for rear projection recordings. A short drying time is guaranteed by high hardening. The base of the NP 3 is colored gray to increase antihalation protection.
