Photofiltre
http://photofiltre.free.fr/download_en.htm
is a free photo editing programme. It is very simple to use and has some
wonderful filters that make amazing changes to photos.
Go to
FIlter - Edges - Monchromatic edges to create the
effect above. Experiment with all of the filters, but don't forget to
'Save As' so you don't lose your original image.
You
can also use it for cropping shapes out of your photos. In this example
the circle tool button has been selected and clicked and dragged around
the face. Go to Image - Crop and the new image will appear, go to
File - Save As and name your image.
When
you import it into a coloured background in Word or PowerPoint though
you will see a white background around the photo.
You
will need to use the Transparent button
on the Picture Menu (in Version 2003) or click on the Format tab -
Recolor -Set transparent colour (in Version 2007). Once you have
selected the Transparent button click on the white area of the photo and
it will disappear.
