Exposure
The Exposure Compensation slider affects the overall brightness of an image as if the original exposure had
been changed. Use this control for slightly under or overexposed images. Each 1/10 increment of the slider
represents 1/10 of an f/stop. The range of the Exposure Slider is two stops in each direction.
Contrast
The Contrast slider affects the blackness of the blacks and the whiteness of the whites with a single control.
Increasing the constrast brightens the whites and darkens the blacks. Decreasing the contrast grays both the
whites and the blacks. The range of the Contrast Slider is –2.0 to 2.0.
Shadow
The Shadow slider affects the blackness of the shadows. Increasing the number makes shadows lighter,
decreasing the number makes shadows darker. The range of the Shadow Slider is –2.0 to 2.0.
Highlight
The Highlight slider affects the brightness of the highlights. Increasing the number makes highlights
brighter, decreasing the number makes highlights darker. The range of the Highlight Slider is –2.0 to 2.0.
Saturation
The Saturation slider affects the intensity of the color in your image. Increasing the saturation makes the
color richer, decreasing the saturation makes the color weaker. The range of the Saturation Slider is –2.0 to
2.0. The minimum saturation value of –2.0 corresponds to a pure grayscale (Black and White) image.
Sharpness
The Sharpness slider affects the clarity of detail in your image. The higher the number, the stronger the
sharpness. The range of the Sharpness Slider is –2.0 to 2.0.
