Film Instructions
By George A. Wallace
1. Introduction
The reflected-light-metering systems provided on most SLR cameras are very
fast and convenient, and they are good enough for general use in capturing
images on negative films. However, they are not good enough for satisfactory
use with color slide films, nor for controlling image tones rather than simply
recording them.
Our ExpoDiscs are the key to direct incident-lightmetering methods that are a
little slower than reflected- light-metering methods, but they do provide for
consistently better exposures on any film in any lighting, and they offer the
photographer accurate control of image tones whenever he wishes to use it.
The procedures provided below should be easily within the grasp, and of value,
to all 35mm SLR camera photographers. The procedures on the following pages
are intended for more serious and advanced photographers who want to get the
most out of their cameras and films.
Enjoy!
