Scenes that are light overall, such as a snow scene, can look too dark in the final photograph if you make just an overall reading or let an automatic camera make one for you. The reason is that the meter will make its usual assumption that it is pointed at a scene consisting of light, medium, and dark tones, and it will expose the film accordingly. But this will underexpose a scene that consists mostly of light tones, resulting in a too-dark final photograph. Try giving one or two stops extra exposure to such scenes.
The Zone System is the simplest and best method yet devised for planning an exposure. Created by Ansel Adams and expounded by Minor White and others, it is more than just a shirt-sleeve approach to sensitometry; it is an elegant method of integrating all the decisions and techniques of exposure control. 8230;
The zone system was invented by Ansel Adams, one of the most famous photographers ever. He was a master of technique, and had an eye for light that few are blessed with. His photographs were the result of a happy combination of comprehensive technique and the knack of taking a picture when the light was at its best. A distinguishing feature of his black and white photographs is how light and dark areas play off each other in an instantly appealing manner.
This chapter discusses how our light-sensitive camera materials work, especially colour films. It traces the way that ingenious principles have been put into practice and compares how films record relative to the way our eyes see subjects directly. So the chapter begins by describing how eyes and brain receive and interpret the sensation of colours and comparing this with the far more fixed chemical response of colour films. Differences between seeing and photographing are important to grasp in order to control results. 8230;
Colour Film consists of three light sensitive layers. Each of which responds to about one-third of the colours in the light spectrum. Each layer is matched to a primary colour dye that is built into the emulsion or added during processing, and every colour in the spectrum can be produced by mixing varying proportions of the colour primaries. 8230;
