Repetition is the use of similar or connected pictorial elements. For example, similar shapes, colors or lines that are used more than once.
In this photo of honeycombs, I see many honeycombs that are filled with honey and many that aren't. The repetition, can be seen in the empty and filled honeycombs . This repetition conveys a sense of union in my opinion. This image is appealing to me because while it has similar shapes and colors they're in very random and crazy in placement .
In this photo of a valley of windmills, I see many windmills on mountains in very crazy and random patterns. The repetition, can be seen in the windmills that are all over the hills. This repetition conveys a sense of unity in my opinion. This image is appealing to me because it's very random where it places the windmills but it still keeps its repetition.
