I started by uploading the image that I chose up to photoshop.
I then chose the 'magic eraser tool' from the tool bar along the side of the screen.
I then started removing the background bit by bit, not touching the models within the image.
Once i had removed the background, i chose the 'eraser tool'.
I used this tool to clean up edges around the models and any part of the background which could have been left behind.
Then once that was complete, i was left with my final edited image.
(This was the process i used with all of my edited images, as i only ever wanted to remove the background from them and that is all.
