Hi Charles, wonderful captured zigzag Tabellaria with the perfectly arranged mucilage pads which hold the cells together, I really love it. I wondered, what I find "wrong" with image 2 and 4, now I got it : The DIC contrast is inverted, it seems, the lighting comes from the lower side.... Thanks for...

PCB with ceramic capacitor
http://www.photomacrography.net/forum/userpix/69_pcb2cap1_1.jpg Another piece of computer PCB multilayer, with SMD ceramic capacitors in cross section. Several capacitor layers are visible here. In this preparation with diamond grinding discs several small parts of the capacitor obviously broke away.

http://www.photomacrography.net/forum/userpix/69_PCB2l_1.jpg Thank you very much for all your kind comments. @Mike, 1 mil for the lower copper thickness could be correct. From my measurment this is about 30µm, the upper layer about 35µm, just the thickness of normal one-layer PCBs you use in your h...

Multilayer PCB / image with dimensions added
http://www.photomacrography.net/forum/userpix/69_PCB2_1.jpg Recently I've been fiddling around with cutting PCBs into little pieces and take a closer look to the technical details after grinding and polishing. Additionally I have been infected by Charlies invention of UV flashlights for photomicrog...

Hi Charly, woaah, the stereos are absolutely stunning results with your setup, overwhelming indeed. With my filter-cube epi illumination there is a terrible blur all over the details, your images look like confocal images ! With your setup, do you have a visible red blur ? And another question: I gu...

I think this is a simple misreading of the numbers on the plate. 8, 5 and 3 are identically seen, due to the low scan resolution. I think Michael means #5 for his identification, this is M. americana. Please remember, the old taxonomists always tried to find accurate Latin or Greece words to describ...

Thank you very much for the kind comments and questions ! @ Jörgen: that is an interesting question, not completely answered in literature. I think, they are commensalic guests, harmless. I sometimes found worms with about 400 ciliates inside. These worms did not show any indication of harmful paras...

Astomatous Ciliates living in earthworm guts, image added
http://www.photomacrography.net/forum/userpix/69_anoplotop_1.jpg This is an astomatous ciliate of the genus Anoplophrya, living in earthworm guts. These strange ciliates live as commensals in the gut of compost worms which can easily be found in your compost heap. The ciliates are completely colorl...
