Crop

Cropping an image is a great way to improve the quality of a photograph by improving how it is framed. You crop a photo by selecting the part of the photo you want to keep. If you want your photo to be the exact dimensions necessary for a certain print size, you can constrain the kind of selection F-Spot will allow you to draw by choosing the appropriate size from the Constraint drop- down list. See the Remove Red-Eye section above for details on making a selection on your photo.

After you made your crop selection, click the Crop icon underneath the photo to finalize the crop. If you are working with the original photo, cropping creates a new version of your photo.

Remove Red-Eye

To remove red-eye from a photo, select a zone containing the eyes. You might want to zoom in on the image to accurately select the eyes in the photo. You should be able to correct both eyes on the same person in one shot, or even the eyes from multiple people at once. If this doesn't work for you, or the selected zone contains some vivid red parts (such as lips), you will probably have to correct one red eye at a time.

To make your selection, click one corner of the rectangle that will be your selection, and drag your mouse to the diagonal corner and release it. You can resize your selection by dragging its edges, and you can move it by clicking in the middle of it and dragging it to where you want it.

After you have selected a zone, remove the red by clicking the Red-eye icon underneath the photo.

Sharpen

Access this function by clicking Edit Sharpen. Adjust the values for Amount, Radius, and Threshold to your needs, then click OK.

Soft Focus

Sharpening one region of a picture while blurring all the rest is a way to make emphasis and grab attention. It is achieved by using a lens that allows shooting with a short distance in front of and beyond the subject that appears to be in focus. The soft focus effect is a way to emulate such a lens.

Choose the central point of the area you want to be in focus, then click the Soft Focus icon underneath the photo. Adjust the amount of blurring, then click Apply.

Straighten

The Straighten effect helps you level a photo and is quite useful when editing landscapes taken without a tripod (when the imaginary line of horizon is not at 0°). This tool rotates a photo by a specified angle and automagically crops the resulted image so that you always see a perfect rectangle.
