I can tell the opacity and lasso tools were used on this photo. I like this series because its pretty self explanatory and it gets a powerful message across. 

I think the magnetic lasso was used to highlight the wrist and arm and erase it to leave the hand in the back pocket. I like this photo because of the creativity. I think it was clever to leave the hand attached to the phone. It emphasizes the danger in today's technology.

I think the dodge tool was used on this photo. 

I like that they used the pencil vs. camera idea because it helps the message get across.
