Artists have long used the golden ratio as a guide for creating aesthetically pleasing art, as it's believed that the human brain is hardwired to find the proportions inherently beautiful. Take a look at the work of legendary photographer Ansel Adams, and you may find the golden ratio tracing out many of their notable features.
A long time ago I was a young art student, being told about the “Rule Of Thirds.” I was told it’s one of the most important fundamentals of art and photography, as it helps you get the right composition in your images.
xkcd's latest comic, titled "Flowcharts," is a tongue-in-cheek take on the concept of the golden ratio (or golden spiral) in photography. It's a flow chart in which one of the steps reads: "Do you like when people find the golden spiral in random images?" If you choose "yes" from there, you're taken on a golden ratio journey that magically fits the design of the chart.
