In the film world, knowledgeable photographers manipulate colors to suit their artistic vision through their choice of film. Some types of film emphasize blues and greens, for example, while others subdue those same hues and enhance warmer tones. A huge array of color lens filters provide additional control over how a scene is rendered. Digital photographers obviously can t swap out image sensors the way that film photographers change film. But filter manufacturers such as Tiffen and Kenko now offer a variety of traditional filters in sizes to fit digital camera lenses. In addition, you can use your camera s white-balance control to give pictures a warmer or cooler tone. Some cameras even provide controls for fine tuning color saturation. This chapter explores just a few of the ways that you can manipulate color with traditional filters, digital features, or both. You ll also find some easy techniques for producing similar results in your photo editor.

Every light source emits a particular hue, influencing the colors of the objects it illuminates. Candlelight infuses a scene with warm, reddish tones, for example, while cloudy daylight adds a bluish tint. The color of a light source, often referred to as its color temperature, is measured on the Kelvin scale. You can see an approximation of the colors of common light sources on Page 26 of the color insert. Read the sidebar Measuring Degrees of Color if you want to know more about the Kelvin scale. Our human eyes are pretty good at compensating for the various colors of light. We perceive a white shirt as being white whether we re looking at it across a candlelit table or outdoors on an overcast day. But cameras need a little help in this area. In the film world, specific films are produced for use with different light sources. On a digital camera, the light-compensating function is performed by the white-balance control. If you leave this control set to automatic, the camera adjusts to the color temperature of the light source for you. As a rule, white-balance mechanisms do a pretty good job in automatic mode. But if you re working with multiple light sources that have different color temperatures say, a flash plus window light the camera can get confused. For this reason, most cameras offer a manual white-balance control that enables you to select from five or six specific light sources. Typically, you get a setting appropriate for cloudy/overcast skies, flash, bright sunshine, fluorescent lights, and incandescent light (household bulbs). Some advanced cameras also offer a setting for studio lights that use tungsten bulbs. In addition, some cameras provide an auto white-balance compensation feature. This feature works similarly to exposure compensation, enabling you to make the exposure a little warmer or cooler than one of the standard settings provided. For example, if you re working on a partly cloudy day, you can choose Cloudy +3 or Cloudy 3 if you want the image to be slightly warmer or cooler than the Cloudy setting produces. Although the main purpose of white balance is to enable you to record colors accurately in any lighting, you also can use the feature as a sort of virtual warming or cooling filter, as follows:

that s higher on the Kelvin scale than your actual light source. In bright sunlight, for example, choose the setting for flash or clouds. (Fortunately, your LCD monitor will show you how your image colors shift as you cycle through the various white-balance settings, so you don t need to memorize the Kelvin chart.)

that has a lower color temperature than your actual light source. Again, on a sunny day, the incandescent or fluorescent setting would produce cooler tones. I used this approach to create the variations on my carousel image on Page 26 of the color insert. Note, however, that how much color shift you get varies from camera to camera. Of course, if you re working on a cloudy day and you re already using your camera s cloudy setting, you can t get any warmer. Nor can you go cooler if you re shooting in incandescent light and using the incandescent setting. The next two sections discuss some other options for times when you re maxed out in the white-balance department.

You can use a traditional warming or cooling filter in conjunction with manual white balance to produce a more pronounced color shift than either delivers alone.
