Diatom (3 Comments) (link)
 Friday, 23-March-2007  17:48:26 (GMT +10) - by Rational

Bevan sent me a nice follow up to the photography post I made a few days ago which may interest you. The photography Bevan told me about is a little bit different than much of the other photography that gets posted which is macroscopic, this is photography on the microscopic level.

Here is something a little different from you current photos, it's a Diatom I took last night using the gear owned by Delta Environmental (I was setting it up).

These little guys (there are over 100,000 different types) make up a large amounts of the marine biomass, they are probably the number one group of species on this planet. They are mostly single-celled and microscopic (like this one) but some are multi-celled and macroscopic (you can see them with your naked eye). This one is called a "Navicula lyra" which probably means as much to you as it does to me... nothing :).

For those technically inclined, the microscope was a Nikon E600 with differential interference contrast (DIC). The camera is a Pentax *ist DL2 SLR, with a USB link to the PC next to it so you can remotely fire it and change its settings.
