Guide to image processing tool

There are multiple tools that will result in the same effect. One may be easier or more flexible than
another. The most suitable tool for a specific job will depend not only on the required results but
also the experience of the operator; all changes made with any of the palettes can be reset or
undone (p. 66).

Variation palette: a simple image processing tool. Corrections are
made by choosing the best image from a group of slightly corrected
samples (p. 69).

Brightness
Contrast
Color balance
Saturation

Hue, saturation, and lightness palette: advanced and creative
image-processing tool to change image color and brightness (p. 81).

Brightness, contrast, and color-balance palette:
corrections can be made easily with the use of sliders (p. 70).

Tone-curve and histogram palette: advanced image processing
tool using a graphic representations of the luminance levels and dis-
tribution within the image. Adjustments can be made to highlights,
mid-tones, and shadows in the color and luminance channels (p. 71-
78).

Selective-color palette: advanced tool to make precise adjustments
to a specific color group without influencing any of the other color
groups in the image (p. 79).

Effects

Tools and functions

Brightness/Lightness:The intensity of image luminance or how light or dark a picture is.
Contrast:

Affects the difference between highlights and shadows; an increase in
contrast makes the light tones brighter and dark tones darker.
Adjustment to contrast can affect the apparent image sharpness.

Color balance:

The relative strength of the overall color of an image. Color balancing
makes an image with a color cast appear natural.

Saturation:

The vividness of the colors.

Hue:

A distinct color within a color space. Changes to hue reassign colors
depending on their position in the color space.

Sharpness:

The clarity of image detail.
