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).

Tools and functions Effects

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, 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).

Unsharp mask: advanced tool to sharpen edges and detail in the image (p. 80).

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

Image processing glossary

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.
