• Dehaze is based on a physical model of how light is transmitted, estimating the amount of light that is lost due to absorption and scattering
through the atmosphere. Move the slider to the right to remove the haze, move the slider to the left to add a creative haze eect.
- Dehaze makes dramatic changes to the shadows and lower portion of the Histogram while only slightly adjusting the highlights.
- For the best results, set the white balance for the image before using Dehaze.
- Option (Mac) | Alt (Win) -drag the slider to preview areas that are being clipped to pure black without detail. .
• Vibrance is a relative and biased slider - it increases/decreases the amount of color in an image based on how much color there was to begin
with and, it adjusts orange, red, and yellow values less than other colors. Vibrance can be very useful when increasing saturation in blue sky,
green grass etc., while avoiding most shifts in skin-tones.
• Saturation is an absolute adjustment. Moving the slider to -100 will remove all color from an image, +100 will fully saturate colors in an image.
Note: You can use a combination of both sliders (Vibrance and Saturation) to adjust colors. For example, you may want to make a negative adjust-
ment using Vibrance to decrease the greens and blues, then increase the entire color palette using Saturation.
12. The Curve Panel
• Use the icons across the top of the Curve panel to move between Parametric, Point Curve, and individual Red, Green, and Blue channels. or,
use Option + 1, 2, 3, 4 (Mac) | Alt + 1, 2, 3, 4, to select the Composite, Red, Green, and Blue channel.
• Command + Option + Shift + T (Mac) | Control + Alt + Shift + T (Win), selects the Targeted Adjustment tool for the Parametric Curve. Click
-drag up/down in the image area to raise/lower the value clicked upon.
• Command + Option + Shift + P (Mac) | Control + Alt + Shift + P (Win), selects the Targeted Adjustment tool for the Point Curve.
• When using the Parametric curve:
- Drag the Highlights, Lights, Darks, and Shadows sliders to lighten/darken the image.
- To change the tonal range aected of any of these sliders, reposition the dots directly under the curve to adjust the “splits”.
- Control -click (Mac) | Right-click (Win) in the Parametric Curve grid area to quickly reset regions and splits.
• When using the Point Curve:
- Command -click (Mac) | Alt -click (Win) in the image area to set a point on the curve.
- Drag to reposition the point in the Tone Curve panel or use the up, down, left, right arrow keys to precisely reposition the point as necessary.
- A maximum of 16 points can be added to each curve to make color corrections and/or add creative eects.
- Select the Red, Green, or Blue Channel Icons (the circles) to adjust the adjust the individual red, green, and blue channels.
- Plus (+) and Minus (-) move between control points on the Curve.
- Tap the D key to deselect the Curve.
- Shift -click to select multiple points in the Curves panel at once.
- Use the Input/Output text boxes to adjust the value of any selected control point.
- With a point selected, tap Delete to delete individual points on the Point Curve or, click -drag the point o the curve.
- Control -click (Mac) | right-click (Win) in the Point Curve grid area to access additional options including: Reset Channel, Reset All Channels,
Copy/Paste Channel Settings, and Show All Curves.
To save a custom Tone Curve, click the More icon at the bottom of the toolbar and choose Save Settings. Use the disclosure triangle to the right
of the Curves option to save either a Parametric or Point Curve. Saving the Curve to the default location will enable Camera Raw to display the
curve in the drop-down menu in the Curves panel (as well as make the custom curve available in Lightroom Classic). The Default locations are:
- Mac (user)/Library/Application Support/Adobe/CameraRaw/Curves
- Win (user)/Application Data/Adobe/CameraRaw/Curves
13. The Detail Panel
• Zoom into 100% to accurately view the eects of Sharpening and Noise Reduction.
• When sharpening, the amount is the amount of contrast added to edges and the Radius determines how many pixels along the edge are
eected. The Detail and Masking sliders suppress sharpening in the lower contrast areas of an image. As a rule of thumb, the Detail slider is
better at suppressing sharpening in high-frequency images such as landscapes while the Masking slider is better when working with portraits.
• Option -drag (Mac) | Alt -drag (Win) the Radius, Detail and Masking sliders (as well as the Luminance sliders in Noise Reduction), to display
a grayscale preview of the slider’s eect. Previewing the edges of the masks (when using the Detail and Masking sliders), can be helpful in
determining which option is best for the image that you’re working on.
• Under Color Noise Reduction, increase the Color Smoothness amount to help reduce low-frequency color mottling in an image.
