The Repetition of Like Forms
Elementary treatises on composition advise looking for and capturing photogenic repetitions of similar objects, a fundamental technique. These motifs can be overused, but have not become clichés in my estimation, because subjects can vary so widely. A better description might be stock-in-trade or standard equipment. The street vendor whose cart appears above has carefully arranged his abundant merchandise in repetitious piles, and thus caught my eye near a beach in North Africa.
I am sharing an image below in the same mode, this time with repeated cactus spines and their slim shadows.
