I started by selecting the Quick Selection Tool
I then traced around the outline of my models.
I then clicked on 'Select the pixel mask' so only the background was left.
I then inverted the picture so my models were separated from the background.
I then clicked mask edge to bring some of the hair that I had originally cut off of my models heads.
Finally, i used the magic wand tool to remove the rest of the green that was in between the arms.
This is the process that I used for all of the photos that I cut out for my magazine.
