Mooncaine: corrected punctuation & grammar; rephrased sentence for clarity; changed "only way" to "a useful way" since there are other ways of dealing with the problem, though probably none as useful as this.

 If you shoot the same scene from a slightly different point of view, the foreground will be shifted in relation to the background, as in this example image.
