First I put the images in photoshop into a stack. Once I had all of my images and layers, I gave them all masks and I changed my foreground and background colors to black and white. I then used the brush tool to start erasing the boy away. I clicked ctrl I or command I after he was erased. I did this for all layers until Ii got to the last one. I made sure to touch the image up to make it look better in the end.
