Sir, you did this with DIC or obilque light?

thanks!

it is not DIC, it's my universal filter - it mixes obligue light with rheinberg illumination and thanks to that gives very dic-like effect

images taken with the universal filter are also here: http://www.photomacrography.net/forum/v ... hp?t=16690 or here: http://www.photomacrography.net/forum/v ... hp?t=16445

The mouth is very interesting to me.

From your direct observations, are those small teeth limited to the ends of the filaments, sort of like bristles on a toothbrush? Or do the teeth go farther down the filament, and we're only lucky enough to see a few at the ends?

I am not sure how deep of a stack you would want here. This could become confusing very quickly. Perhaps a stereo rendering...

yes, they looked like some kind of toothbrush, I will try to take a better image of them but it is quite hard in my case.

there should be a very deep stack, at least 100 images, that's impossible for me right now. I'm able to do only 'handmade' PS stacks consisting of no more than 5-6 images...

That details, that look like some kind of toothbrush, on the last one are very nice.

That universal filter si amazing.

thank you (:

here is another image of that strange filaments, I will try to make a better one, maybe I will try to cut some of those. There should be used at least 40x objective, but the specimen is way to thick to get a good quality image.

EDIT:

I menaged to detach the mouth from the head (- sorry about that, buddy; it's for a good cause... - @#$#@%*#@* - I know, I know...), flattened it and did 4 image stack of the filaments, that's all I can do right now. the 40x objective gives bad images /:

Thank you for the followup. It's clear from the short stack that the teeth go quite a ways down the filaments, where in the first picture it looked like there were maybe only 6-8 teeth at the end of each filament.

Most amazing. I don't see how you get such good images, let alone manipulate that little bug to get the right angle.

thanks (: I still think they could be much better. the universal filter allows to choose light direction (: it also reduces image distortions typical for traditional obligue light.
