Image on Image

I chose to use this particular image because i thought it would be neat to upload my face into another image.

The first step i took was to save an image that i wanted my face to be uploaded in, and upload it into Photoshop. The next was to an image of my head, that I thought could replace the head of the person within the image. Now I had two tabs with different images in Photoshop. I dragged one of the tabs out, so two images that I could work with appeared. I chose the lasso tool, and drew an outline of my head. Once I had finished the outline, I chose the move tool and dragged the image into the other image, over top of the head. Now, my head appeared way too small! So what we do from there is choose 'Edit' and then 'Free Transform' to modify the proportions of the head.
