[Note Guidelines] Photographer's Note
As I had promised in my last posting, here I will demonstrate the inner architecture of the archaic Chambered Nautilus (Nautilus pompilius) shell in a para-sagittal section, i.e., in a section cut parallel but slightly outside of the sagittal, or symmetry plane of the shell to clearly show the tubular perforations of the numerous septa, forming the duct-like structure which encloses the siphuncle proper of the living animal. Also visible are the cross-sectioned septa formed periodically as the mollusc grows, which incidentally also act as quite strong "bulkheads" of a submarine, structurally strengthening the "hull" or shell tremendously, so it can actually withstand great pressures encountered as deep as nearly 800 meters in the ocean. The so-called logarithmic or equiangular spiral growth pattern of the shell is also quite evident from this section, which also displays the smooth, highly polished nacreous inside coating, finely visible especially on the wall of the last chamber occupied by the living animal (for further details, please see the notes of my previous post).
By the way, another interesting peculiarity of the Chambered Nautilus is its unusually long living habit, usually more than 20 years, compared with the rest of the modern day cephalopods, which live at most but a few years. This long life brings also another peculiarity of this mollusc group to mind regarding their reproductive powers. They are the only living iteroparous spawners among the cephalopods, a mature female Nautilus is capable to spawn once every year, while the rest of the cephalopods are typically semelparous animals, their females can spawn only once in their relatively short lifetimes!
To photograph this section, the specimen was placed within a truncated cone made from tracing paper to diffuse the light from two photofloods, utilizing a black BG to emphasize the shell structure.

İnanır mısınız gerçekten bir fotoğrafa mı bakıyorum yoksa yanılıyor muyum diye şöyle bir gözlerimi kırpıştırdım. Bu gerçekten eşşiz bir kare ve değerli bir mücevher, elmas kaltesinde. İnsanı içine çeken bir derinlik ve berraklıkta. Sizi yürekten kutluyorum hocam. Emeğinize sağlık.

Hi Mehmet,

This is a masterpiece! The clarity is amazing - the cut section glows. Magnificent colors and unbelievably wonderful details. The cross sections are marvelous in their intricacy and symmetry. I think you have reached perfection with this.


Fotoğraf kalitesinin yanı sıra benim için çok ilginç bir kare...

Hi Mehmet

After the big presentation, here is a closer look of the structure of this interesting and very old submarine.
It's exactly how i remembered it to be...and here in your photo, it looks lovely.
All the details are impeccable sharp and show this very beautiful geometrical 3D pattern well.
Excellent section and very good overall presentation.

bravo and TFS

Hello Mehmet,
I've got some cross sections of shells myself and I think they're so interesting and beautiful. You're showing this Nautilus shell very sharply here with amazing depth. Lovely details and beautiful colours too. Excellent work!

Merhaba Mehmet,
A superbly presented parasagittal sectional view of a Nautilus shell, the technical aspects of your photography being first class to make this an excellent illustration.
You clearly show in this image that the chambers are linked, but I have sometimes wondered whether the animal occupies all the chambers or whether only the most recent are used while the older ones work as variable buoyancy.
Thank you for posting this beauty together with you customary excellent note.
All the best,

Love being able to look into the shell. And of course, the poem immediately jumps to mind "This is the ship of pearl, which, poets feign.."- one verse from The Chambered Nautilus by Oliver Wendell Holmes below:

Year after year beheld the silent toil
That spread his lustrous coil;
Still, as the spiral grew,
He left the past year's dwelling for the new,
Stole with soft step its shining archway through,
Built up its idle door,
Stretched in his last-found home, and knew the old no more.

Hi Mehmet,
A nice capture of this beautiful shell's inner architecture. Very well composed with sharp details and well described too. Thanks a lot for sharing.

hello Mehmet
so beautiful
big sharpness and nice colours
greeting lou

Merhaba Hoca, detaylar, pozlandırma ve siyah zemin ile alışılmış sıradışı çekimlerinizden biri. Özelliklede gaz odacıkları nefis görüntülenmiş.

Hi Mehmet!

I have not visited your gallery for quite a moment and I'm delighted to discover it again. The image you present us today stands for all the former ones. The quality is superb, everything on the technical side is perfect: lighting, sharpness, colour management. Moreover, your technique with the dark blackground highlights the shapes and patterns at best. And, finally, all this reveals nature's beauty in a very particular and pleasant way.

Thanks for this!

Kind regards


Merhaba Mehmet, an other fantastic shell from you, fine details, wonderful light and colors, superb sharpness, splendid macro, very well done, ciao Silvio

Hi Mehmet . This is one of the best you have posted on TN . The detail and your focusing is first class. the shape and colours are amazing. good use of the light against the dark BG. well done TFS.

My dear friend Mehmet,
I wish I felt as safe as the Chambered nNautilus in todays' world of violence!This is an exceptional shpt, withan exceptional note (as usual) from you!
Thanks so much for this detailed shot and the education you provide us with your precise, perfect notes!

Salam Mehmet.

This is even more beautiful from the underside. The rotating opening looks brilliant and you have captured the image very well here.

Well done!
TFS and warmest regards,

Hi Mehmet,
Very nice presentation showing the intricate design/symmetry of the interior chambers..
Excellent work, worthy of publication :)

Salam Mehemet,
Very informative details emerge out of this composition that is not only beautiful to look at but also impressive in its own natural formation.I wasnot able to make out that the presentation here is a parallel cut section - and was wondering why do you have the title as "Innard..",but on opening I see this really interesting inside of the submariner.
The shape itself is so aesthetically appealing and the texture and the colours are well accentuated by the black BG.

I am glad your notes are so well detailed... it surprises me to know it lives on for 20 years.Thanks for both...this gallery is ready reference material:)

Merhaba Mehmet Bey,sedef bir broş gibi çok gözalıcı bir kare olmuş.Çok ince fırça darbeleriyle işlenmiş gibi,nefis bir ışık kullanımı yine,ellerinize sağlık,saygılar :)

Reminds me of a movie...20,000 leagues under the sea! AND I have a fossil with one of these in it...care to see?


Olá Mehmet

Simplismente encantadora esta foto.
O formato, os desenhos, as cores, o brilho, tudo me encanta...um excente trabalho de quem é apaixonado pelo assunto.

Hello Mehmet,
Brillant photo showing the inner architecture of an archaic
Beautiful shell outside but marvellous inside, very interesting note too
TFS and have a good W-E

Hallo Mehmet
An excellent example of perfect workmanship. No two hands would have been able to create a beautiful piece of art as the one in front of me, as that is exactly what it is. A delicate piece of art, captured through the lens of yet another photographic artist Mehmet Atatur, and beautifully displayed with uttermost preciseness. To round it off the subject is described in full detail for our pleasure and learning experience. I thank you kindly sir, for sharing this true piece of beauty from the ocean with us.
Best regards

amazing section, TFS Ori

Outstanding shot of this magnificent sea shell and the details are so crisp, clear and beautiful. Seems like a work of art and nature has crafted it so diligently. Superb handling of flash lighting and again the black BG creates magic. Excellent composition.

Hi Mehmet,
did you cut this yourself? Very impressive, you have the skills of a surgeon! Fascinating and educational post...the photograph isn't bad either ;o) Superb work, very well done my friend.

Fascinating structure, Mehmet.
You diffused the light very well.
Beautiful Chambered Nautilus.
Thanks for sharing.

Hello Mehmet.

Excellent image, very good details and composition.

I must say that this is the most unique TN gallery! This is a great collection of shots and most of all knowledge. I wish I had more time to go though some of your shots and read up your wonderful notes. Fascinating. TFS your excellent work.

Hello Sir, ( our way of showing respect to learned academician)
Thanks for your critique on my lizard. How I appreciate it.
This nautilus is so beautiful, and created in beauty and elegance.
I remembered when a friend of my father came from Langkawi Island in Malaysia ( about 30 years ago) he gave it to my father. They turned it into an ash-tray.
Now I was wondering, with all the beauty, how could it happen. I have a few but it is intact in the display cupboard. thanks to you for giving such an excellent note and information.


hello mehmet,
this looks real professional, you have presented us such a lovely and informative image which we have never seen, the natural colours, the shine on the shell, the dark bg, the perfect lighting makes it a treat to watch,
excellent work,
tfs & regards

Merhaba Mehmet Bey,
I love the form of Nautilus a lot. I am also a big fan of the Ammonites, the fossilized, hard shells of extinct mollusks whose closest relative is the chambered Nautilus. I like to use the ammolite gemstone in jewelery, they have amazing colors :o)Very nice details and textures in this one.

Dear Friend merhaba Mehmet!
I did a tour through your gallery and all I can say is :AMAZING!
You are a great artist! Many congrats! But this one called "Innards of the submariner" I loved so much because I play violin and this sell is like a volute violin...Beautiful!!! Thankyou for sharing. Thankyou also for your kind comment about my photo "Por-de-sol entre coqueiros".
Best wishes,

Hello Mehmet, i like this photo very much!!! The inner lines and colours in contrast to the dark bg result to a beautiful photo. Thanks for sharing, Erodotos
