I would try to explain the math of sunflowers but let’s face it, it’s math, and we all know how good I am at math. NOT! It blows my mind if I can’t count or figure it up on my fingers and toes. A great explanation of the Fibonacci sequence and the Golden Ratio found in middle of a sunflower is located at Nature Blows My Mind! The Hypnotic Patterns of Sunflowers.
For all my photographer friends out there using Lightroom. Did you know you can use the Golden Ratio overlay when cropping photos? While using the crop tool if you press the O key you can cycle through the many crop overlays available. When you find an overlay you like, if you press Shift O you can rotate the orientation of that overlay to fit your image if need be. More information on crop overlays in Lightroom can be found on Have Camera Will Travel.
