[Note Guidelines] Photographer's Note
These "surfboarders" returning to their "boat" moored amongst washed-up "flotsam" are microscopic diatoms which are algae, usually unicellular, that became abundant in the lakes and oceans of the Earth since the Jurassic Period. They have amorphous, biogenically secreted, outer silica shells called "frustules" or "tests" that have such fine detail, to beyond the resolving capabilities of optical microscopes that they are used for checking the resolution of electron microscopes with magnifying power up to 600 000 X. Virtually all the images in this photo, including the OOF ones, are diatom frustules from a diatomite deposit at the northern shore of Lake Sibaya. Diatomite, often called "diatomaceous earth", is used as a very efficient water filtering substance.

The only alteration to the original photo was resizing and some moderate subsequent sharpening. The bright halo around the frustules is not a result of oversharpening but is a Becke line formed by the difference in refractive index between any transparent image and the medium surrounding it - refractive index difference, and not colour, is the main reason why these images are visible at all.

The length of the scale bar is 0.05 mm. Taken with an Olympus BX51 research microscope equipped with dedicated Olympus DP72 digital camera.

Hi Neels,
this is really unusual photo here. But this is very interesting. Nice idea! Incredible, that this is nature - living nature.
Thanks for sharing

very interesting photo, TFS!

That is what I call an image with a difference! Good evening Neels! I do not know much about this type of photography but definitely you are on step above all today! An image of pleasant surprise! Great magnification in the world of unicellular organisms! Bravo Neels!

Hellow Neels,
A nice microbiological lesson for those interested, very different.A clear and neat image although personally for me rather boring, but the image is well portrayed.

Very interesting look into the microscopic world of nature- - a view we often do not get to see here on TN.

Well Done

Dear friend Neels,
Wow! Today you got the whole world by surprise !
Hey George! help me! Can I use your words ?
Well...I make my own the George´s words:"you are on step above all today".Bravo MF!
Best wishes from,

Hallo Neels,
a very interesting microscope shot and beautiful graphic picture
Best regards

Ciao Neels, a different view from microscopy, fantastic graphic and splendid light, very well done my friend, ciao Silvio

Hello Neels,
A fine and interesting micro macro of this diatoms. The clarity and lighting are excellent.
In the TN TOS, laboratory pictures are not allowed but as there is no other way to show microscopic life I think this is a perfectly acceptable and desireable contribution to TN.
Thanks and kind regards,

amazing mocro capture, TFS Ori

Hi Neels,

another your wonderful microphotograph.Another example of the "hidden" world.Hidden but wonderful.Also here the multiplicity of colours and shape is amazing.Surely a different and welcomed image in TN.Note very interesting too.



A fine photomicrograph indeed Neels, no other way to demonstrate these minute life forms, except with microscopy. I hope your research microscope is equipped with phase-contrast optics so you can show us similar scenes in finer detail. Crossed polarising filters plus a quartz wedge might produce bright colours...

Very interesting Neels!!

Very interesting and quite different for that matter, fine work to show these organisms. tfs.

Hello Neels,
this is something really stunning. The view is so excellent, and I felt I'm looking in a microscope.
Good details and lively shapes of the organisms.


Hello Neels,

that's an different kind of nature shot.
Good sharp image and interesting note!.
