Regular Rhythm:
As written above, this picture is an example of regular rhythm, though from the angle of the shot it's verging on progressive. I like this photo because it's an excellent example of how nature works by using such strong patterns. You can tell this is a picture displaying regular rhythm as it shows a series of straight, rhythmic lines.
Progressive Rhythm:
This is an image displaying progressive rhythm, you can tell this as it shows a pattern that changes slightly over time to form a progressive sequence. I like this picture as it's not only a perfect example of how shape can change in a progressive rhythm but also colour.
Flowing Rhythm:
This picture shows flowing rhythm in nature, you can tell this as the patterns show rhythm but with an organic and natural movement. I like this picture as it once again perfectly shows the beauty of nature and how perfectly a set of reactions and formations can create perfect rhythm.
