66 ULEAD PHOTOIMPACT USER GUIDE
Enhancing digital camera photos using
RAW data support
With RAW data support, you can directly edit raw image data from popular digital
camera formats.
PhotoImpact lets you decide how to open RAW files by using essential parameters
such as color temperature and exposure compensation. You can then use the same
settings for batch processing in opening multiple RAW files.
To open RAW files, select File: Open and select the file you want to open. This will
take you to the Open Camera RAW File dialog box.
• White balance Calibrates colors to correctly display white and other colors
according to different lighting conditions. You can adjust white balance
through:
• Scenario Lets you choose the lighting condition applied to the image.
Choose from default scenarios (e.g. As Shot, Daylight, Tungsten etc.) or
choose Custom to manually adjust the color temperature.
• Color temperature Sets the degree of warmth or coolness of a lighting
source while the photo was taken. Lower value means warmer lighting
(e.g. indoor), whereas higher value means cooler (e.g. outdoor).
• Tint Adjusts the color balance between green and magenta. Dragging the
slider to the right increases the degree of green, while dragging to the left
increases the degree of magenta.
• Exposure compensation Adjusts exposure variables for lighting issues.
• Reduce noise Sets the noise degree for luminance and color.
• RGB color type Sets the color type to either 24-bit (8 bits/channel) or 48-
bit (16 bits/channel).
• Apply to all subsequent selected files Applies the settings for batch
processing the remaining RAW files if you have selected multiple RAW files to
open.
