HSL / Grayscale controls in Camera Raw
You can use the controls in the HSL / Grayscale tab to adjust individual color ranges. For example, if a red object
looks too vivid and distracting, you can decrease the Reds values in the nested Saturation tab.
The following nested tabs contain controls for adjusting a color component for a specific color range:
Hue Changes the color. For example, you can change a blue sky (and all other blue objects) from cyan to purple.
Saturation Changes the color vividness or purity of the color. For instance, you can change a blue sky from gray to
highly saturated blue.
Luminance Changes the brightness of the color range.
If you select Convert To Grayscale, you see only one nested tab:
Grayscale Mix Use controls in this tab to specify the contribution of each color range to the grayscale version of the
image.
Tone a grayscale image in Camera Raw
Use the controls in the Split Toning tab to color a grayscale image. You can add one color throughout the tonal range,
such as a sepia appearance, or create a split tone result, 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 treatments, such as a cross-processed look, to a color image.
1 Select a grayscale image. (This can be an image that you converted to grayscale by selecting Convert To Grayscale
in the HSL / Grayscale tab.)
2 In the Split Toning tab, adjust the Hue and Saturation properties for the highlights and shadows. Hue sets the color
of the tone; Saturation sets the magnitude of the result.
3 Adjust the Balance control to balance the influence between the Highlight and Shadow controls. Positive values
increase the influence of the Shadow controls; negative values increase the influence of the Highlight controls.
Adjust color rendering for your camera in Camera Raw
For each camera model it supports, Camera Raw uses profiles to process raw images. The profiles are produced by
photographing a color target under different white-balanced lighting conditions. When you set white balance,
Camera Raw uses the profiles for your camera to extrapolate color information.
Sometimes colors rendered by the Camera Raw plug-in do not look as expected. The cause may be a difference
between a camera’s profile and the profile in Camera Raw for that camera model. Alternatively, the photo may have
been taken under nonstandard lighting conditions beyond the compensating range of the Camera Raw plug-in.
To render non-neutral colors differently, use the Hue and Saturation controls in the Calibrate tab to adjust the
settings for the profile built into Camera Raw. You can also specify whether to use the profiles built into Camera Raw
or a profile built into the file itself.
1 In the Calibrate tab, choose a profile from the Camera Profile menu.
Important: The options in the Camera Profile menu vary, depending on whether the file has a profile embedded and
whether a newer version of the profile has become available in Camera Raw.
ACR 2.4, 3.0, or higher Higher version numbers represent newer and improved camera profiles for some cameras. If
you only see a lower version number, such as 2.4, your camera’s profiles didn’t require updating. If multiple options
are available, you may want to choose a lower version number for consistent behavior with legacy images.
