When using color slide films, you may want to modify these exposures to get the effect you prefer. The less exposure you use, the darker the shadows will be. With more exposure, your pictures will show more detail in the shadows, but the brightest areas, such as neon signs, may be too light. These suggested exposures apply to daylight and tungsten color films. When you take color pictures under tungsten illumination, they look more natural when you use tungsten film.
Daylight film produces pictures more orange, or warm, in color.
Bracketing When you want to be sure to get a properly exposed picture of an especially important subject, bracket the exposure. Take one shot at the suggested exposure, one at 1 lens opening smaller, and another at 1 lens opening larger. If it is a case of now or never, take two more pictures-one at 2 stops more and one at 2 stops less than the suggested exposure. After you have had some experience in taking existing-light pictures, you will be more confident in determining correct exposures. In existing-light photography, it is often a good idea to experiment.
