1. Choose Effect > Color Correction > Curves.
2. If the image has more than one color channel, choose the channel you want to adjust from the Channel menu. RGB alters all channels
using a single curve.
3. Use the Bezier tool and the Pencil tool to modify or draw a curve. (To activate a tool, click the Bezier button or the Pencil button .)
To smooth the curve, click the Smooth button. To reset the curve to a line, click the Line button.
The curve type is determined by the last tool used to modify it. You can save arbitrary map curves modified by the Pencil tool as .amp (Photoshop
lookup) files. You can save curves modified by the Bezier tool as .acv (Photoshop spline) files.
Equalize effect
The Equalize effect alters the pixel values of an image to produce a more consistent brightness or color component distribution. The effect works
similarly to the Equalize command in Adobe Photoshop. Pixels with 0 alpha (completely transparent) values aren't considered, so masked layers
are equalized based on the mask area.
This effect works with 8-bpc color.

Equalize RGB equalizes the image based on red, green, and blue components. Brightness equalizes the image based on the brightness of each
pixel. Photoshop Style equalizes by redistributing the brightness values of the pixels in an image so that they more evenly represent the entire
range of brightness levels.
Amount To Equalize How much to redistribute the brightness values. At 100%, the pixel values are spread as evenly as possible; lower
percentages redistribute fewer pixel values.
Exposure effect
Use the Exposure effect to make tonal adjustments to footage, either to one channel at a time or to all channels at once. The Exposure effect
simulates the result of modifying the exposure setting (in f-stops) of the camera that captured the image. The Exposure effect works by performing
calculations in a linear color space, rather than in the current color space for the project. The Exposure effect is designed for making tonal
adjustments to high–dynamic range (HDR) images with 32-bpc color, but you can use the effect on 8-bpc and 16-bpc images.
This effect works with 8-bpc, 16-bpc, and 32-bpc color.
Master Adjust all channels simultaneously.
Individual Channels Adjust channels individually.
Exposure Simulates the exposure setting on the camera that captures the image, multiplying all light intensity values by a constant. The units for
Exposure are f-stops.
Offset Darkens or brightens the shadows and midtones with minimal change to the highlights.
Gamma Correction The amount of gamma correction to use for adding an additional power-curve adjustment to the image. Higher values make
the image lighter; lower values make the image darker. Negative values are mirrored around zero (that is, they remain negative but still get
adjusted as if they were positive). The default value is 1.0, which corresponds to no additional adjustment.
Bypass Linear Light Conversion Select to apply the Exposure effect to the raw pixel values. This option can be useful if you manage color
manually using the Color Profile Converter effect.
Gamma/Pedestal/Gain effect
The Gamma/Pedestal/Gain effect adjusts the response curve independently for each channel. For pedestal and gain, a value of 0.0 is completely
off, and a value of 1.0 is completely on.
The Black Stretch control remaps the low pixel values of all channels. Large Black Stretch values brighten dark areas. Gamma specifies an
exponent describing the shape of the intermediate curve. The Pedestal and Gain controls specify the lowest and highest attainable output value
for a channel.
This effect works with 8-bpc color.
Hue/Saturation effect
The Hue/Saturation effect adjusts the hue, saturation, and lightness of individual color components in an image. This effect is based on the color
