The first thing that you need is to take multiple photo's with the same back ground. You can always add pictures of things that have different backgrounds but if you use pictures with the same background it is much easier.
Step 2: Setting up the camera.
It is pretty easy to set up a camera so that it will take multiple shots if you hold down the shutter button. If your camera does this it will make it much easier to get multiples than to do it by pushing the shutter. Either way it will work one just takes a bit more patience.
Step 3: Get at least four shots.
I have found that a minimum of four shots makes for a really nice picture. You can try it with less or more and your results will differ. Import them all into your Photoshop program ( I use Photoshop Elements). As you can see at the bottom of the photo I have imported five pictures into this file.
Step 4: Cut out the picture parts to be added.
Now you are ready to go up and grab the "Magnetic Lasso". As you can see from the photo I will have to go up and pick the "Magnetic" lasso from the top of the program. The program on this machine is version #2.
