I need a to do following thing in Photoshop:
I have shot series of photos from a tripod, so they all have the same background. I even took a photo of background itself. Then, there were people moving around the scene.
I need to be able to cut only the people from photos (there are shadows, which are harder to cut), in order to paste them into one layer. What I want to achieve, is that effect, where you have people multiplied in one scene.
As I mentioned, there are shadows, so manually selecting from layer masks does not work well for me.
Can you please point me to some tutorials, or maybe describe to me, how (in PS) to select only those parts of an image or layer, that are different than background layer? (I don't know, how this process is called, so I could not find it in google.)
