Blurring out Faces

This is an example of a student collage I made. I blurred the faces on Gimp 2. I first opened up the picture that I wanted to use to blur the face, then I selected the ellipse select tool and circled around the face that I wanted to blur. Under the filters tab at the top of the page is a blur option. There is a list of options, click on pixelize. Gimp gives you the option to choose the pixel length and width. You can experiment with the numbers but I found that it's best to use between 10-20 pixels.

This is a very useful tool if you want to show off your work (that includes pictures of students) online. All you have to do is blur their faces and you can still get your idea/project across to your audience.
