68 ULEAD PHOTOIMPACT USER GUIDE
Adjusting and enhancing your images
There are some issues to take into consideration when dealing with digital pictures
and scanned images. Problems like overexposure, underexposure, poor lighting, or
incorrect tint can be corrected by using the
Adjust
and
Photo
commands in
PhotoImpact. These commands can be applied to selected areas, objects or entire
images. Below are the most common commands used to fix photos.
Note:
Some of the commands are not applicable to certain data types or they cannot
be applied to selected areas in certain data types.
•
Style
Allows you to select a custom mood for your image by adding a tint or
replacing a selected color's tint.
•
Levels
Adjusts the tonal range of an image by adjusting the intensity levels
of the image's shadows, midtones and highlights. The histogram serves as a
visual guide for adjusting the image's Black, Gray and White tones.
•
Brightness and Contrast
Allows you to fine-tune the luminance of an
image by brightening or darkening each pixel in the image.
•
Color Balance
Takes all the colors in an image and adjusts them based on
two colors specified by the user to make them appear more balanced. The
Color Balance dialog box has two tabs for correcting the color balance:
•
Color Adjustment
Fine-tunes your image's colors by adjusting levels
between Cyan, Magenta, and Yellow and Red, Green, and Blue color
properties.
•
Color Cast
Corrects the unwanted color cast that different lighting
conditions could give your pictures.
•
Hue and Saturation
Allows you to adjust the hue and saturation properties
of an image. Adjusting the hue affects color. Adjusting the saturation either
intensifies or washes out colors. Adjusting Lightness affects the brightness of
the image.
•
White Balance
Calibrates images for accurate color display even under
different lighting conditions.
•
Focus
Adjusts the image's overall convergence to sharpen or blur it.
•
Curves
Adjusts the overall tone or brightness channel of the image.
•
Highlight Midtone Shadow
Redistributes the tone adjustment in an image
to take advantage of the full tonal range. This is used to add, emphasize, or
remove shadows; improve contrast; and enrich highlights.
