USING PHOTOSHOP LIGHTROOM 2 105 Developing photos Done Dismisses the White Balance Selector tool, and the pointer changes to the Hand or Zoom-in tool by default. The Navigator displays a preview of the color balance as you move the White Balance Selector over different pixels. 4 When you find an appropriate area, click it. The Temp and Tint sliders in the Basic panel adjust to make the selected color neutral, if possible. Fine-tune the white balance using the Temp and Tint controls ❖ In the Basic panel of the Develop module, adjust the Temp and Tint sliders. Temp Fine-tunes the white balance using the Kelvin color temperature scale. Move the slider to the left to make the photo appear cooler, and right to warm the photo colors. You can also set a specific Kelvin value in the Temp text box to match the color of the ambient light. Click the current value to select the text box and enter a new value. For example, photographic tungsten lights are often balanced at 3200 Kelvin. If you shoot under photo tungsten lights and set the image temperature to 3200, your photos should appear color balanced. One of the benefits of working with raw files is that you can adjust the color temperature as if you were changing a setting in a camera during capture, allowing a broad range of settings. When working with JPEG, TIFF, and PSD files, you work in a scale of -100 to 100 rather than the Kelvin scale. Non-raw files such as JPEG or TIFF include the temperate setting in the file, so the temperate scale is more limited. Tint Fine-tunes the white balance to compensate for a green or magenta tint. Move the slider to the left (negative values) to add green to the photo; move it to the right (positive values) to add magenta. If you see a green or magenta color cast in the shadow areas after adjusting the temperature and tint, try removing it by adjusting the Shadows Tint slider in the Camera Calibration panel. Adjust overall image tonal scale You adjust the overall image tonal scale using the tone controls in the Basic panel. As you set the white and black points, keep an eye on the end points of the histogram, or use the shadow and highlight clipping previews. 1 (Optional) In the Tone area of the Basic panel, click Auto to set the overall tonal scale. Lightroom sets the sliders to maximize the tonal scale and minimize highlight and shadow clipping. 2 Adjust the tone controls: Exposure Sets the overall image brightness, with a greater effect in the high values. Adjust the slider until the photo looks good and the whites are at the right level. Use Recovery to bring highlight values down. Exposure values are in increments equivalent to f-stops. An adjustment of +1.00 is similar to increasing the aperture 1 stop. Similarly, an adjustment of -1.00 is similar to reducing the aperture 1 stop. Recovery Reduces the tones of extreme highlights and attempts to recover highlight detail lost because of camera overexposure. Lightroom can recover detail in raw image files if one or two channels are clipped. Fill Light Lightens shadow to reveal more detail while maintaining blacks. Take care not to over apply the setting and reveal image noise. Blacks Specifies which image values map to black. Moving the slider to the right increases the areas that become black, sometimes creating the impression of increased image contrast. The greatest effect is in the shadows, with much less change in the midtones and highlights. Updated 03 September 2009
