Nice shot, did you also focus stack it? I’m just starting to learn about photomicrography so I would like to know ways to overcome the tiny depth of field.

Nice image, I have a few fossil snails in stone I may post at some point in time with the stereo scope.

Thank u Bryan and Rodney - Bryan, yeah i used focus stacking for the snail shell, I think it's the main method that is used for DOF, besides using camera lenses at extremely high aperture settings i don't know any other way to achieve it. each frame in the shell image was a stack of around 30 to 70 shots using the microscope focus knobs to move the object through the focus (point/plane?) between each shot.

Rodney, it would be awesome to see the snail fossils especially if doing a closeup

Very nice! What background did you use, black flocking paper?

This is a small fossil snail I spoke about.

Thanks 75RR - I just placed the shell on a slide and removed the condenser below it, leaving it hanging in semi-darkness - then darkening the background even more when editing

Rodney,looks interesting and seems to have a nice texture

With that snail photo I had camera focus problem with any settings. The view through the eyepiece was at least 3 times better.
I used a tactical led x800 flashlight for illumination and the camera would never focus correctly. I think I will try different types of light filters and compare the results.
Looks like the fossil snail is mostly solid limestone. I found this one in a rock void or crack, so one hit with a hammer and metal chisel sent the snail flying. They usually don`t turn out this good, you generally get a lot of busted up parts unless you have all the proper equipment.
I will try several more fossils later.
We got slammed by hurricane Michael so i`m still working and will be.

I made a few changes and increased the magnification with this photo of the fossil snail. i`m not sure what the species is.

Some interesting replies over at the fossil forum in the ID section; I listed this snail in the topic as Fossil Snail. One such reply is unknown gastropod.

oh wow, that shot is very much improved, can see the lovely textures on the white area(s) - thanks for sharing
