Vignetting

 - The brush tool.

Before

After

 you click on the blur option then gaussian blur. 

                                   The first thing i had to do is called 'vignetting' by doing this we                                 had to select a picture we wanted to edit, and make a new layer, then select the brush tool, then you have to add a border by clicking the colour you want, then when your adding the border hold 'shift' down and drag along to make the border, by holding shift it makes it straight, then we had to blur the image, above is before and after of the image, by bluring it we had to click 'filter' 'blur' then 'glaussian blur', then your image will be blurrier then before, like above.
