Processing and developing photos

Preview highlight and shadow clipping
You can preview tonal clipping in a photo as you work on it. Clipping is the shifting of pixel values to the highest
highlight value or the lowest shadow value. Clipped areas are either completely white or completely black, and have no
image detail. You can preview clipped areas as you adjust the tone sliders in the Basic panel.
Clipping indicators are located at the top of the Histogram panel in the Develop module. The black (shadow)
clipping indicator is on the left, and the white (highlight) indicator is on the right.
• Move the Blacks slider and watch the black clipping indicator. Move the Recovery or Whites sliders and watch the
white clipping indicator. An indicator turns white when clipping in all channels occurs. A colored clipping indicator
means one or two channels are clipped.
• To preview clipping in the photo, move the mouse over the clipping indicator. Click the indicator to keep the preview
on.
Clipped black areas in the photo become blue, and clipped white areas become red.
• To view clipped image ares for each channel, press Alt (Windows) or Option (Mac OS) while moving a slider in the
Basic panel of the Develop module.
For the Recovery and Whites sliders, the image turns black, and clipped areas appear white. For the Blacks slider,
the image turns white and clipped areas appear black. Colored areas indicate clipping in one color channel (red,
green, blue) or two color channels (cyan, magenta, yellow).
Set overall color saturation
❖ In the Presence area of the Basic panel, change the color saturation (vividness or color purity) of all colors by
adjusting the Clarity, Vibrance, and Saturation controls. (To adjust saturation for a specific range of colors, use the
controls in the HSL/Color/Grayscale panel.)
Clarity Adds depth to an image by increasing local contrast. When using this setting, it is best to zoom in to 100%
or greater. To maximize the effect, increase the setting until you see halos near the edge details of the image, and
then reduce the setting slightly. See the video tutorial:
The Basics - Clarity .
Vibrance Adjusts the saturation so that clipping is minimized as colors approach full saturation, changing the
saturation of all lower-saturated colors with less effect on the higher-saturated colors. Vibrance also prevents skin
tones from becoming over saturated.
Saturation Adjusts the saturation of all image colors equally from –100 (monochrome) to +100 (double the
saturation).
Fine-tune the tonal scale using the Tone Curve panel
The graph in the Tone Curve panel of the Develop module represents changes made to the tonal scale of a photo. The
horizontal axis represents the original tone values (input values), with black on the left and progressively lighter values
toward the right. The vertical axis represents the changed tone values (output values), with black on the bottom and
lighter values progressing to white at the top. Use the tone curve to tweak the adjustments you make to a photo in the
Basic panel.
