Upon observing repeating patterns in the subjects, you may find them pleasing to shoot. Of course, some things are not so readily apparent. Anyhow, if you’re on a photographic walkabout, watch out for repeating patterns.

Note that these patterns also exist in organic subjects (sometimes arranged by Mother Nature herself)…

Once you’ve mastered this, go one step further to introduce an element that breaks the repeating pattern. Finding this element is of course a whole new challenge but will allow your photograph something for the audience’s eyes to latch on to.
