In all the quieter aspects of lighting this range from black to white paint is sufficient. But where strong, brilliantly lit effects are wanted, something has to be sacrificed, if this look of brilliancy is to be made telling.
In order to increase the relationship between some of the tones others must be sacrificed. There are two ways of doing this. The first, which was the method earliest adopted, is to begin from the light end of the scale, and, taking something very near pure white as your highest light, to get the relationships between this and the next most brilliant tone, and to proceed thus, tone by tone, from the lightest to the darkest. But working in this way you will find that you arrive at the greatest dark you can make in paint before you have completed the scale of relationships as in nature, if the subject happens to be brilliantly lit. Another method is to put down the highest light and the darkest dark, and then work your scale of tone relatively between them. But it will be found that working in this way, unless the subject in nature is very quietly lit, you will not get anything like the forceful impression of tone that nature gives.
The third way, and this is the more modern, is to begin from the dark end of the scale, getting the true relationship felt between the greatest dark and the next darkest tone to it, and so on, proceeding towards the light. By this method you will arrive at your highest light in paint before the highest light in nature has been reached. All variety of tone at the light end of the scale will have to be modified in this case, instead of at the dark end as in the other case. In the painting of sunlight the latter method is much the more effective, a look of great brilliancy and light being produced, whereas in the earlier method, the scale being commenced from the light end, so much of the picture was dark that the impression of light and air was lost and a dark gloomy land took its place, a gloom accentuated rather than dispelled by the streaks of lurid light where the sun struck.
Rembrandt is an example of beginning the tone relationships from the light side of the scale, and a large part of his canvas is in consequence always dark.
Bastien Lepage is an example of the second method, that of fixing upon two extremes and working-relatively between them. And it will be noticed that he confined himself chiefly to quiet grey day effects of lighting, the rendering of which was well within the range of his palette. The method of beginning from the dark side, getting the true relations of tones on this side of the scale, and letting the lights take care of themselves, was perhaps first used by Turner. But it is largely used now whenever a strong impression of light is desired. The light masses instead of the dark masses dominate the pictures, which have great brilliancy.
