A Black and White Negative is a reversal of the tones in the original scene. Where the scene is bright, the negative develops many dense, dark grains of silver. These dense areas hold back light from the paper, they prevent the formation of silver in the papers emulsion and so creates a bright area corresponding to the bright area in the scene. Where the scene was dark, the negative is thin or even clear. It passes much light to the paper and dark silver is formed in the emulsion, resulting in a dark area in the print.
Color films take advantage of the fact that nearly all colors can be reproduced by mixing only a few basic or primary colors. Color films are made with three color-sensitive layers, each of which records the wave lenghts of lights in a different third of the color spectrum. Colors negative film is processed to be the opposite in colors and density of the original scene; then it is printed onto a sheet of sensitized paper to make a positive color print.
This is why I shoot color films to Print out my Black and White Photos the Classic way. Color films gives more details in my prints. The colors remain true and the tones are richer. I use the actual color photo as a guide when my Hand Tint my Black and White Prints.
