Using Juxtaposition in Landscape Photography

What does juxtaposition mean?  In short, it is placing two objects together to either create comparison or contrast.  Using it correctly it can draw a person's attention to your photographs for example in landscape photography you could perhaps have a half-demolished building in the foreground and a newly built skyscraper in the background.

In landscape photography it could also help with adding depth of field to your photograph.  By placing an object in the foreground i.e. a man sitting on the rock on the beach with a beautiful mountain range in the background.

You could also compare people, young and old, parent and child, etc.  You could use it for comparison by taking a picture of twin babies playing or an elderly couple sitting on a bench in the park, etc.

Here is an example of a picture I took using contrast:
