I Taking Photographs-White Balance White Balance Measuring Preset White Balance To measure a value for preset white balance: 1 Place a neutral gray or white object under the lighting that will be used in the final photograph. 2 Set the function dial to WB. If preset white balance is not selected, rotate the main command dial until PRE appears in the control panel. 3 Rotate the sub-command dial. A flashing will appear in the exposurecount displays, and the PRE icon in the control panel will flash. III 4 The camera will be set to the exposure mode chosen in the WB Preset > Exposure Mode menu; adjust focus, exposure, and flash settings. Note that settings that would result in extreme under- or over-exposure could prevent the camera from measuring a value for white balance. Under studio lighting, use an 18% diffusion panel to make the reference object appear gray. If you are using a white object as the reference for setting white balance, exposure should be set to a value that would cause the reference object to appear gray. Use Manual Focus When measuring preset white balance the focus-mode selector to M (manual focus; 74) and focus manually. At a setting of single-servo autofocus, lack of contrast may prevent the camera focusing on a neutral gray reference object, and the shutter-release will be disabled. 56 I II
