The most important menus are:
Image
Use Edit Comments & Tags to enter comments to a particular image and to assign
a tag (category) to this image. Properties takes you to a window consisting of three
tabs providing general information, EXIF information, and the histogram of this
image.
Fix
This menu contains some of the editing functions most needed in digital photogra-
phy. Colors takes you to a submenu where you can modify all basic color settings.
You can also blur or sharpen either the entire picture or just a part of the image
you selected. To reduce red eyes in a portrait shot, roughly select the eye region
of the face by just clicking and holding the left mouse pointer and gradually expand-
ing the selection, select Red Eye Reduction and choose either mild or aggressive
reduction depending on whether you selected a whole region or just the eyes.
Transform
The Transform menu offers the crop, rotate, flip, and resize functions. You can also
use the Aspect Ratio Crop option to produce crops in a fixed aspect ratio.
Filters
If you need to transform your color shots into black and white or want to achieve
an aged look in your photographs, check out the Filters menu and choose from the
various export options.
