New Album Settings

 Choose Album+ImportAdd Images from the menu and use the standard file dialog to select the pictures you want to add to your newly created album, then click on Add.

[Tip] Tip

You can add all the pictures contained in a given folder by choosing Album+ImportImport Folders from the menu and browsing for a folder, instead of files.

4.2. Touching-Up Pictures

Double click on a picture to open the image edit window. Note that all touch-up operations may affect the quality of the picture's on-disk file. Also bear in mind that on-screen rendering is quite different from printing your digital pictures on photographic paper. So if you intend to both print and publish your pictures for online viewing, it might be wise to treat both copies differently from the beginning.

[Tip] Tip

Press Ctrl-Z to undo the last transformation operation. However, once you have saved the image, changes cannot be undone.

Rotation

 Simply choose one of the entries (90º, 180º or 270º) of the Transform+Rotate menu.

[Note] Note

When rotating pictures “by hand” it is better to correct the EXIF orientation information in order for EXIF information to reflect the picture correctly. On the album browsing window, select the image and choose the appropriate entry of the ImageCorrect Exif Orientation Tag menu.

Brightness, Contrast and Gamma

 Choose Fix+ColorsBrightness/Contrast/Gamma from the menu and use the sliders to adjust the brightness, contrast and gamma of the picture using the picture copy as a guide.

Sharpen

 Choose FixSharpen from the menu, drag the square to the part of the image to be used as a guide, and use the slider to sharpen the picture.

Red-Eye Reduction

 Select the pupil of the eye to fix, choose FixRed Eye Reduction from the menu, and then select the aggressive (only part of the eye selected) or mild (more than the eye selected) option to reduce the red-eye flash effect. Repeat for the other eye, if needed.

Image Resizing and Cropping

 Multi-megapixel images are excellent for photographic paper print-ups, but are far from adequate for e-mailing or publishing on the web. Choose TransformResize from the menu, then select the desired size, either in pixels or in percentage, and whether or not to keep (recommended) the aspect ratio.

 You can also crop an image to a desired size while keeping the aspect ratio. Choose TransformAspect Ratio Crop from the menu, drag the square to frame the part of the image you are interested on and select the aspect ratio, orientation, width and height (one follows the other according to the aspect ratio selected).

[Tip] Tip

For electronic publication, the usual aspect ratio is 4:3, while for printing the usual aspect ratio is 3:2.

Usually a size of 640x480 is enough for e-mailing a photo, while 800x600 is enough for web publishing.
