At the Heart of the Helianthus - a photo on Flickriver

            ...the 55|34 secret is hidden...

#MacroMonday
#Spiral

Please (double) zoom in :-)

I don't know whether the exact 55/34-formula applies to this capitulum - it does to most sunflowers, and the sunchoke is a member of the Helianthus family; but like most spiral forms found in nature, it is based on the famous Fibonacci sequence (and as far as formulas, sequences and such are involved, I'd happily entrust you to Wikipedia, because all the math stuff has always been way beyond me 😉 ) Isn't it fascinating how many spirals we find in nature? From the tiniest shapes found in shells, snail shells, flowers and cones, to the most huge ones, the galaxies - and all of them are perfect logarithmic structures. This natural spiral definitely is on the smaller side, the capitulum (I hope it's the correct term) of this sunroot is just 1,7 cm / 0,67 inches in diameter. This is a focus stack composed of 52 images, combined in Helicon Focus, method B (radius 14, smoothing 7). I have an image of another blossom from this sunchoke bouquet which I liked a little better, because that capitulum had more green in it, but the spiral here is nicer 
and also much better defined, so I've decided to add this to the MM photo pool despite it being a little too "all over yellow".

Have a sunny week ahead, dear Flickr friends, stay safe and healthy! HMM, Everyone!

Ist es nicht erstaunlich, wo sich in der Natur überall Spiralformen finden lassen? Angefangen bei winzigen Schnecken- oder Muschelgehäusen, Zapfen (Tannen-, Fichten- usw.) aller Art, Blumen... bis hin zu riesigen Spiralgalaxien, zu denen auch unsere Heimatgalaxie, die Milchstraße gehört. Die meisten in der Natur vorkommenden Spiralen sind als Fibonacci-Folge angeordnet, so auch der Blütenkorb dieser Topinambur-Blüte. Diese Art der "Blütenspirale" kann man selbst bei Gänseblümchen finden. Ich hatte hier noch eine weitere Version von einer anderen Blüte, die zu dem schönen Topinambur-Strauß, der zurzeit mein Wohnzimmer schmückt, gehört, die mir an sich besser gefallen hat, weil mehr Grün darin war, aber hier kommt die Spirale besser zur Geltung, weshalb nun dieses Foto die offizielle MM-Version geworden ist - selbst wenn es ein wenig sehr (eigentlich fast ausschließlich) Gelb ist. 

Dies ist wieder ein Fokus-Stack aus 52 Einzelfotos und zusammengefügt in Helicon Focus (Methode B, Radius 14, Glättung 7).

Ich wünsche Euch eine sonnige Woche, liebe Flickr-Freunde, passt immer gut auf Euch auf!
