horsetail impressions

Recently we saw some very detailed micro photos of grape vine leaves posted here by seemann. He had used nail varnish to make an imprint of the leaf's surface. I was much amazed to see such excellent results, for I had tried this method too in my experimenting years, and had rejected it. If I rememb...

Re: fluorescence metoo

First thing, check the spec sheets of the different bulbs. They could be different manufacturers versions with the same specs, which SHOULD be ok to use interchangeably, but I'll admit it is not something I'd want to do without knowing more about the bulbs. If not, then best to just use the origina...

A LED lamp, but check what excitation wavelength you want to use.
would be interesting to see the effect of the 1600V starting current on the LED. I don't think it will emit at a specific wave length, but for sure it will be SHORT. :D

fluorescence metoo

For some years I have awed at the beautiful and colourful images posted here, taken with the fluorescence microscope. And by each one I firmly confirmed my personal resolution that I wouldn't be doing that, I draw the line before the high pressure mercury lamps step into my house. Oh well, that was ...

Dear Toni,

Do you think you could draw a diagram showing all lenses and other separators in sequence? I am afraid I have trouble interpreting the photo and subsequent descriptions...

Those anthers move with the slightest air movement or change in humidity. How did you manage to keep them motionless?

Re: Vorticella - fastest moving organism?

Lou, a Peregrine falcon flying under my microscope would probably give me quite a shock!
Which is nothing, compared to how that falcon would feel.

Re: Afocal Leica SM-LUX Project

4. Is there a condenser or stage for these scopes that will accept a polarizer filter, or should I plan on running one on the illumination housing? I have a (photographic) polarizer filter that just lies on top of the lens barrel where the light leaves the stand and projects up into the condenser. ...

I don't know what's more astonishing, that someone would try to put a flies eye in front of a microscope objective or that someone would know that someone has tried it before! :?:
Haven't we all tried this once (and failed completely)? :oops:

a succesful case of post-shading

At this forum, at a few coocasions (e.g. https://photomacrography.net/forum/viewtopic.php?t=41752 ) we have discussed creating hillshade maps from depth maps in order to apply shading during post rather than during exposure. To some extent ths worked, but the resulting hillshade maps remained course...

Re: Leaf casts - Images

Love the Rheinberg. My preference is otherrwise. The Rheinberg adds disturbing colous, but no additional information. What makes the first image even more special, since it shows 3D surface features without being transparent. Metoo is very interested in how you made these. I'd have good use for it.

Re: centering springs

Brilliant solution! Now let me think how I could make that. Perhaps two ridges would do as well in this case.

Re: Pyrrosia

Very nice. In addition to Rik's questions, may I ask what was the NA of the objective? The depth map seems almost noiseless. That's the easier question of the two: MPlan 20x/0.40 but that doesn't explain the smoothness. Depthmaps are most of the time full of spikes and pits and without blurring the...
