No. I haven't gone all Dan Brown/DaVinci Code on everyone. Sure, Brown used Fibonacci numbers as clues in his best-selling religious thriller but that has little to do with photography.
Or does it?
Fibonacci's ratio can be geometrically translated a number of ways. One way is into a spiral called, as you might have already guessed, the Fibonacci Spiral. It's a spiral almost identical to another cool spiral called the Golden Spiral. In nature, these spirals are seen often enough. For instance, we see them in spiral galaxies, leastwise in pictures or through a telescope, and we see them in some sea shells. Spirals like these are also seen in photographic and other artistic compositions. Some call it "Divine Composition." Divine Composition is like the Rule of Thirds gone god-like.
There's an entertaining, quick-read, blog post about this Rule of Thirds and Fibonacci stuff (as it applies to photographic composition) on photographer Jake Garn's web site. Click Here to check it out.
BTW, I'm not suggesting you come up with some sort of a Fibonacci overlay template when fine-tuning your work. (Via cropping in post.) Doing so, leastwise for me, would be adding a way too scientific and technical aspect to that part of my work I consider the art part rather than the science part. Still, I often pose, frame, or crop my models with an obvious nod to the Rule of Thirds and, who knows? Maybe the spirit sometimes moves me to apply a bit of Divine Composition to some of my pics? Perhaps even without realizing what I'm doing? You know, sort of like being possessed, albeit not demonically possessed.
Wait! Maybe I am demonically possessed? Especially considering the content of much of what I shoot. Plus, there's all that photography stuff about the Devil being in the details. And I'm definitely a guy who pays attention to the details in my photography work. Oh well. It doesn't really matter if I'm divinely inspired on occasion or the Devil makes me do it as long as my pics turn out okay and the checks clear.
There's no Fibonacci Spiral evident in the full-frontal nude pic of Jayme I attached to this update but, I have to admit, she both divinely inspires me while simultaneously eliciting some devilish thoughts in my head.
