Select
• The method uses the Fuzzy Select Tool - a fairly quick and precise method
that can be mastered easily.

9. • Select the Image Background
• Using the Fuzzy Select Tool select the part of the image that you wish to
remove. The aim is to end up with an image which resembles the one below.
• You should have the "marching ants" around the area of the image that you
wish to keep

10. • Background Selected
1. Select a large even colored area in the background to start with.
2. Add to the background by clicking on other parts of the background. Be
sure to change the Fuzzy Select Mode to "Add to the Current
Selection" this can be done from the tool options or by holding down
the Shift key.
3. Once you have selected the bulk of the image background you may need
to zoom in to finish it off properly.

selection more or less sensitive.

easily fixed by changing the Fuzzy Select Mode to "Subtract from the
Current Selection". This can be done from the tool options or by
holding down the Ctrl key.

12. 2. Add Transparency to the Image

Alpha Channel. This makes it easy to add another background layer or
paste your selection into another image.

with your selection on a checked or transparent background.

JPG files don't support transparency. The transparent part of the image
will be filled with white.
