On this photo i desturated the photo which takes all the colour out and turns it black and white then i changed the brightness and contrast which can make it more white when you turn the brightness up and contrast can make the photo more black.

 On this photo i used the elliptical marquee tool and drew a circle around jacks head, i then changed the feathering tool and put it up to 80 from 0, then clicked select, then inverse which means you change the outer of the circle. I then went and changed the brightness and contrast which made jacks head more bright and the area around him darker, like the wall and his jacket so it draws more attention to his face, this is called vingnetting. i then went in filter-sharpen and unsharpen mask, and changed the radius to 2.2 pixels and the amount to 80, which sharpened things up slightly. i then used the doge tool to lighten jacks eyes and used the dodge tool to darken certain areas of his face. 
 

 All that was done on this photo was that i clicked image then auto colour, which brings out more colour in the photo and has made it a more puple/blue colour.

 

On this i used the burn tool to darken jacks eyes and make it look as though he's been punched, which looks quite scary i also used it on his lip area and nose area i then got the colour red tool and put that on the side of his face to make it look more realistic, after this i used the dodge tool to lighten his eyes.
