Do you want to know how it's done? Learn how to use Photoshop the easy way!
In this tutorial we are going to clone a person. Using this technique, you will not have to carefully select a subject and remove the background. This tutorial is designed to be very simple photoshop wise. the only prerequisite is that you will need to use a tripod.
What you will want to do is find a decent location for your photo. With the camera on the tripod and your subject set in place, snap a picture. Now have your subject move to another location while leaving your camera in the same position on the tripod. Snap another picture. These images are what we will be working with. Here are the pics that I used.
Open one of your images in photoshop. Then open the other image into photoshop. Using the Move Tool, drag the background picture onto the foreground picture. This will create 2 layers into one document. You may need to drag the new layer around a bit to line it up properly.
Since we have perfectly aligned background images, it is just a simple process of deleting some of the background of our top layer. Select the Lasso Tool.
Now make a selection around the subject on your top layer. We don't need to be too careful here at all. Just a quick crude selection will be fine. The only thing you will need to watch out for is to make sure that your subject in the background layer is not within your selection.
Now choose Select/Inverse, and hit delete. This will delete everything on the top layer except for what you have selected. Hit Ctrl+D to deselect.
Unfortunately since I have taken this photo indoors with a flash, there is a slight variance in the exposure.
This is easy enough to overcome. Since my selected area is darker than my bottom layer, I just need to lighten it up a bit. Select Image/Adjustments/Levels. Move the slider on the left a little to the right to blend. You can see this change in real time as you adjust.
And here is how it turned out.
