Making Image Adjustments 37
• Colour Balance: Lets you adjust colour and tonal balance for general
colour correction in the image.
• Replace Colour: Tags one or more ranges of the full colour spectrum
that require adjustment in the image, then apply variations in hue,
saturation, and/or brightness to just those colour regions (not to be
confused with the simpler Replace Colour Tool).
• Selective Colour: Lets you add or subtract a certain percentage of
cyan, magenta, yellow, and/or black ink for creating effects.
• Channel Mixer: Modifies a colour channel using a mix of the current
colour channels.
• Gradient Map: Lets you remap greyscale (lightness) information in
the image to a selected gradient. The function replaces pixels of a given
lightness in the original image with the corresponding colour value
from the gradient spectrum.
• Lens Filter: Adjusts the colour balance for warming or cooling down
your photos. It digitally mimics the placement of a filter on the front of
your camera lens.
• Black and White Film: Used for greyscale conversion with
controllable source channel input.
• Threshold: Creates a monochromatic (black and white) rendering.
You can set the threshold, i.e. the lightness or grey value above which
colours are inverted.
• Equalize: Evenly distributes the lightness levels between existing
bottom (darkest) and top (lightest) values.
• Negative Image: Inverts the colours, giving the effect of a
photographic negative.
• Clarity: Lets you sharpen up your photos using local contrast.
• Posterize: Produces a special effect by reducing the image to a limited
number of colours.
