Hi guys, a simple quizz to test your 3D capabilities. I find it still hard sometime to really get a good feeling for how I see something in the sample and how it is shown in the books. This thingy is a typical example. It's just weird how it's looking from an angle. It's a pretty common diatom, also...

Hi Steffen, steep price you paid for it, but I guess that's the curse of modern infinity. You have to compete with professionals and dito pricing. Didn't realise Nikon uses DIC on their objectives only to mention it COULD be used for DIC. But it makes sense, and the 2 might indicate condenser settin...

Nice lens, stm, this NA is typical for a semiapo 40x. The more shallow depth of field is noticable in pics, but not really so much more then the standard 0.65. Same for it's sensitivity for coverslips. Even with the apo's 40/0.95, it's difficult to set the correction collar for coverslip thickness v...

Well, it brings it back to attention again
Yes, by now it should be in the technique section, you're right about that. My primary interest is mainly in the dinoflagellates, not in the equipment.
BTW, don't get carried away by the size, all pics together barely amount to 110kb.

It almost looks like you shot these pics in the museum where they show these glass sculptures of radiolaria, like one of them is shown on this site http://hjs.geol.uib.no/marinemicro/. Anybody know of a site showing the whole collection???

The lorica almost looks like a line drawing, amazing detail. I know that a new lorica starts growing within the mother one, but here it almost looks like branching. Once I made quite a nice image in phase of this kind of gold algae, photo's in the time, of which I gave one to a favourite girl as a b...

Got a live sample in today, from a marine/brackish lake within the Netherlands (Grevelingen). Spring is coming? A bloom from Heterosigma triquetra , length around 25 µm. http://www.photomacrography1.net/images/7742.JPG http://www.photomacrography1.net/images/7742-43HF.jpg Absolute gorgeous alive, th...

Wouldn't want to keep this jewel from you. I haven't seen this one before, I do however come across the smaller variety 'minimum' often, very similar to this one, but always covered in detritus. Like the flag on the mudpole... This one is fixed with Lugol's iodine. http://www.photomacrography1.net/i...

Couldn't resist some pics of my betaversion: http://www.photomacrography1.net/images/7683.jpg http://www.photomacrography1.net/images/DSCN7703.JPG A russion waterimmersion is screwed on the adapter in this inverted. On top the 1ml cuvette with sample can be seen. Light coming out from the back of th...

Nice! Not seen it happening, no. Pseudo-nitzschias form chains like this, but strong. By mucilage secreted in the cell ends, more or less similar thing happens: division, then the diatom slides along it's mother cell and then stays attached along the bottom. Now diatoms stick easily, eg on glass. Co...

btw, you didn't recalibrate your monitor, did you? The greys are gone.

Hi Charlie, I've checked up on it, based on very limited information I would say your critter is Askenasia acrostomia. This is based on the following (soft) proof: first pic shows a couple of needle like structures. I am led to believe they are extrusomes, and they seem proper needle like, not thick...

You did find those little bits back in the sample, did you?

Nice work Jens!

I suppose we can go on and on on this subject, but I leave it after my last remark: using a normal eyepiece (for 'virtual' use) for projection on a chip or film, introduces spherical abberation. I've got tables for the correction in tubelength needed for that, maybe that's what Jens was referring to...
