Re: First attempt at a thin section with a manual microtome
The bench microtome you mention should work very well. I never use a handheld microtome holding it with my left hand, so the cutting precision is not obtained in my opinion and it needs a clamping to a workbench, table or kitchen counter.

Re: First attempt at a thin section with a manual microtome
Hi, Before buying a rotary microtome you should consider several things: the purpose of course (animal or plant tissue), what type of blade will you use ( the large blade with triangular shape difficult to sharpen and expensive or the thin disposable and cheap) what type of paraffin block (cube-shap...

Re: First attempt at a thin section with a manual microtome
Hi again,
With a manual microtome, the blade and "cutting art" are critical. I never use the blade standard of a microtome. I use a razor blade mounted on a thick handle like glass scrappers to best control

Re: First attempt at a thin section with a manual microtome
Hi, In my humble opinion, a very thin section is useful for botanists but lacks the beautiful 3D look for a considered photogenic image. I've tried with embedded paraffin and a lab microtome ,and sections over 20 microns usually roll up on themselves making them useless, but is not impossible. Not a...

Re: Abalone shell
Amazing! I always like your artistic way of presenting your photos whatever the subject of attention. This makes the difference, the sense of art, much more than a technique

Re: Diatoms: Star and Triangle shaped
Wow, excellent images for me!!! Could you tell us more about your setup? Direct projection means that you don´t use the trinocular head, nor relay lens and the camera is directly attached over the nosepiece, right? So, the 100x magnification belongs entirely to your objective. The same magnification...

Re: Hibiscus rosa-sinensis pollen
Thanks Bob. Some days ago I was thinking about SEM for pollen study. Well I think I would gain in detail, resolution and 3D vision , but the beauty and color of those almost crystalline spicules would be lost

Re: Hibiscus rosa-sinensis pollen
Hi Rik Yes, it was a mistake. Because I knew the process I assume my mind directed my fingers. It is a whole Dmap from top view to bottom and some partials Dmap of 50 pics all stacked with Pmax. After that retouched layer by layer to retrieve information or improve it. Nothing special I think, I'm s...

Re: Hibiscus rosa-sinensis pollen
Welcome, that's a really nice pollen, looks like a certain human malware that's still roaming. :shock: Excellent details! Looks like a piece of crystal. (Minor correction: It's Dmap, not Dmax) Thanks for your appreciation. In fact, it is a personal Dmap/Pmax to prevent noise accumulation ,overlappi...
