Collagen

I knew collagen can be intensely birefringent but in res. papers and in my previous slides never got much feeling for it. They were mostly rather dull. Then by chance got a new (but not recently made) tendon etc. slide and it blew the lid off. It was also surprise since from the outset it seemed pre...

Re: Coverslip thickness

To avoid micrometering every cover glass in a batch... there is apparently an emerging ISO standard 1.5H which guarantees 0.17-0.18mm. It seems to have come with superresolution microcopy stuff but everyone could benefit (at hi mag). Not as easy to find but several outlets exits, ThorLabs, Zeiss etc...

Re: diatom arrangement - Dunkirk, MD

These things are so refreshingly oldfashioned. Timeless, opposite to all the modern visual garbage and quick fix nonsense!
Thanks for showing.

Re: Some autofluorescence

Very nice work, beautiful palette & detail.
Vigneting is easy to fix in the post. You have just a problem of too good a camera ;-)

Beautiful images, really nice work.
I'm usually partial to stills but your videos are also outstanding!

Re: Plocamium cartilagineum stichidia

Nice work! Beautiful dreamlike life form.
Just out of curiosity, why did you flip the image inbetween, just esthetic preference or what?
Cheers, Karl

Zeto later, it's now embedded in a jumble of wires, lights, power units etc. I'll shoot it after its next reincarnation.

Re: Wandering into fluoroverse

Thanks Pau and Scarodactyl for nice comments! Pau, I read your article a way back with great interest. That's a very through and clean conversion you made. I also seem to recall that before entering to that project you asked here about the usefulness of OI-17 but didn't get much response. Later on w...

Wandering into fluoroverse

A regularly appearing impression in this forum and elsewhere seems to be that getting started with epi-fluorescence microscopy is a very complicated and expensive proposal. This does not need to be the case - let me just present a small case study on this matter. First clarification: fluorescence wi...

Re: Rendering shiny carapace(s) - glossy or matt?

Good question. Similar judgements come up all the time when making exhibition prints or e.g. choosing photobook paper. Glossy paper has best black, brightest white, ergo best contrast when done right. But... the inevitable glint (or even worse, double reflection if under glass) can ruin the visual i...

Re: Monochromatic Microscopes?

A good summary of ASML's (and implicitly e.g. Zeiss') role in this tech/political game: www.brookings.edu/techstream/the-chip-making-machine-at-the-center-of-chinese-dual-use-concerns/ Hitech doesn't get much higher than this. Rather humbling to know that both Canon and Nikon are in this business bu...
