Photoshop tutorial

In today's lesson we had a tutorial of how to use photoshop, going through each specific buttons an learning what they do. I benefited from this as I have never used photoshop before an learnt that you basically work by layers. Iv posted a picture of something I created whilst I practiced using the software. I used the magnetic tool to cut out Emily from the original background, an brought up a new background of the Eiffel Tower. I then clicked ctrl+a and ctrl+c on emilys picture and ctrl+v on the Eiffel Tower background to paste Emily onto it. Then used buttons to make Emily smaller an moved her to the position I wanted.
