A presentation concerning the steps on how to use the basic highlights of the GIMP App.

2. This tutorial will take you through the process
of removing image backgrounds step-by-step
using the freely available GIMP software. This
tutorial assumes you are running the
Windows version, but the concept applies
equally to other versions of the gimp and
other photo editing software such as
Photoshop.

4. Step 1 - 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.

5. Additional Steps
1. Select a large even couloured 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 you will need to zoom in to finish it off properly. I
find that zooming to 400% works well.
4.You will most likely need to adjust the threshold as you go to
make the selection more or less sensitive.
5. You may find that you have selected some areas that
shouldn't be. This is 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.

6. Step 2 - Add Transparency to the
Image
Add transparency to the image by using Layer >
Transparency >Add Alpha Channel. This makes it easy to
add another background layer or paste your selection into
another image.
Add Alpha Channel

7. Step 3 - Delete the Background
Press the Delete key to remove the selected background. You
should be left with your selection on a checked or transparent
background.

8. Background Removed and Jagged Edges

9. Step 5 - Save the Image
If you are saving th eimage as a JPG (which
you probably would be for display on a
website) you will need to select Export when
prompted as JPG files don't support
transparency. The transparent part of the
image will be filled with white.

13. Image blending
