Processing and developing photos

Convert a photo to gray tones
Black & White Mix in the B&W panel converts color images to monochrome grayscale images, providing control over
how individual colors convert to gray tones.
1 Convert the photo to grayscale by selecting Black & White in the Treatment area of the Basic panel or by pressing V.
2 Adjust the photo’s tonal range using the settings in the Basic and Tone Curve panels.
3 In the HSL/Color/B&W panel, darken or lighten the gray tones that represent colors in the original photo.
• Drag the individual color sliders to adjust the gray tone for all similar colors in the original photo.
• Click Auto to set a grayscale mix that maximizes the distribution of gray tones. Auto often produces excellent
results that can be used as a starting point for tweaking gray tones using the sliders.
• Click the Targeted Adjustment tool in the upper-left of the B&W panel, move the pointer over an area of the
photo you want to adjust, and click the mouse. Drag the tool, or press the Up and Down Arrow keys, to lighten
or darken the grays for all similarly colored areas of the original photo.
To apply grayscale mix automatically when converting photos to grayscale, select the Apply Auto Mix When First
Converting To Black And White in the Presets area of the Preferences dialog box.
Tone a grayscale photo
Use the sliders in the Split Toning panel to color a grayscale photo. You can add one color throughout the tonal range,
such as a sepia effect, or create a split tone effect in which a different color is applied to the shadows and the highlights.
The extreme shadows and highlights remain black and white.
You can also apply special effects, such as a cross-processed look, to a color photo.
1 Select a grayscale photo.
2 In the Split Toning panel of the Develop module, adjust the Hue and Saturation sliders for the Highlights and
Shadows. Hue sets the color of the tone; Saturation sets the strength of the effect.
3 Set the Balance slider to balance the effect between the Highlight and Shadow sliders. Positive values increase the
effect of the Highlight sliders; negative values increase the effect of the Shadow sliders.
Working with single-channel grayscale images
Grayscale mode images from Photoshop have no color data, but you can make tonal adjustments to them in Lightroom
using the tone adjustments in the Basic panel or Tone Curve panel. You can also apply color toning effects using the
options in the Split Toning panel. Lightroom handles the photo as an RGB image and exports it as RGB.
Apply local adjustments
The controls in the adjustment panels in the Develop module let you affect the color and tone of an entire photo. But
sometimes you don’t want to make adjustments globally, to the entire photo. You want to make corrections to a specific
area of a photo. For example, you may want to lighten a face to make it stand out in a portrait or enhance the blue sky
in a landscape. To make local corrections in Lightroom, you can apply color and tonal adjustments using the
Adjustment Brush tool and the Graduated Filter tool.
The Adjustment Brush tool lets you selectively apply Exposure, Clarity, Brightness, and other adjustments to photos by
“painting” them onto the photo.
The Graduated Filter tool lets you apply Exposure, Clarity, and other tonal adjustments gradually across a region of a
photo. You can make the region as wide or as narrow as you like.
