Re: Smithsonian Magazine on Snowflake Photography
If you would like technical details let me know what you are curious about. I worked with Nathan and a small "crew" building this microscope, and photographing in Fairbanks and Yellowknife.

Abalone shell
Very little luck collecting small critters this time of year, so I dusted off my abalone shell and had another look at it. https://www.krebsmicro.com/forumpix/0779_small_aba.jpg https://www.krebsmicro.com/forumpix/0602_small.jpg https://www.krebsmicro.com/forumpix/0646_small_aba.jpg https://www.kreb...

Inside a rosehip
I've long wanted a 2X for my MM-11 setup since 4X/5X was often too tight for a good "overall". Came across a good price on a USMC 2X, so I bought it. One of my first subjects was this rosehip. This was the first time I ever opened one and had a peek inside. Interesting. USMC 2X https://www.krebsmicr...

Bladderwort (Utricularia sp.)
Fascinating aquatic carnivorous plant. (With a somewhat unfortunate name.... try telling the wife and kids "Hey, come look at this really cool bladderwort"! For some reason doesn't sound as intriqueing as a "venus fly trap" or a "sundew"). https://www.krebsmicro.com/forumpix/7728_bladderwort.jpg htt...

Re: plant leaf stem cross sections
Hi Charles,.. I've always wondered, does a Vibratome tend to cut with less need for support of the material? I would assume so, especially if the settings were just right. Can one alter the frequency and stroke of the commercial machine? It wouldn't be too difficult to make something with both bein...

Lysichiton americanum (Western Skunk Cabbage) sections
These sections are from the central "stalk" of a skunk cabbage plant. Overall the stalk is very "spongy". This is clearly seen in the top two cross section images. You can also see the xylem and phloem tissue interspersed in the first image. The second image is a closer look at this. The third image...

Re: plant leaf stem cross sections
Is it acquired skill or special equipment that results in such perfect sections? (Probably both...) Thanks for the comments. I'm just starting to play around with this subject for myself. I have used a Vibratome at a lab where I work, but at home here all I have is one of those small, inexpensive h...

Re: Nikon Diaphot TMD w/ DIC -- Help!
Late to the party here but a few items... I seriously doubt that Nikon just ignored the increase in distance, My TMD came set up for DIC and fluorescence (I don't use it) so I have that ~20mm increase. I would be curious for those who do not have this to look at their nosepieces. My nosepiece (and I...

plant leaf stem cross sections
Sliced up a few more plants into skinny small pieces :wink: First we have the leaf stalk (petiole) of a lilac bush (Syringa vulgaris). I cut these sections just at the start of the leaf base, where the leaf blade is just beginning to "flare" out. This is what you see as sort of "ears" in the top thr...

Re: Broccolini cross section,. Iris stem cross section
... All were darkfield illumination... Perfect ! Simple DF only ? No hidden tricks ? Some staining, polarisation etc ? Sorry about that. No intention of hiding anything. These were indeed stained in a very basic manner. (I suppose I thought that would be apparent). The sections were cut with a hand...

Broccolini cross section,. Iris stem cross section
Came across some of Robert Berdan's excellent plant section shots and was inspired to dig out my old hand microtome. I raided the veggie compartment for some broccolini (cross between broccoli and Chinese broccoli), and then picked an Iris from my yard. I managed to get some shots and only cut my fi...
