Marcin inquired: "I wonder what I need to make digital photos"

Patience + trial and error technique ;-)

Marcin's microscope: "My microscope MBC-10"

Marcin, this is the same microscope that Alex uses and that I use too. It's a
relatively inexpensive but sturdy Russian stereo microscope and if you buy
list member Jim Tobin's polarizer adapter, you can take all those fascinating
pictures in cross-polarized light like the one I took of the D'Orbigny TS that
I recently got fom you - for those who haven't seen that picture yet, go to RFS

Marcin:

"I tryed several Digital cameras but this not fit or make blur photos or
with very small view area. Ofcourse, I need photos of my thin sections"

After focusing as best I can and after adjusting the exposure time and lens
opening (aperture),...again: use trial and error technique,...I gently place
the digital camera's objective on one of the 8x eyepieces, set the camera's
self-timer to take the picture after ten seconds, breathe in, breathe out,
breathe in again just a little bit, keep my hands still and...click, here we
go. Of course, it will take time and patience and if I attached the camera
to the eyepiece, the result would even be better. But it is OK with me and
I am proud that even such an illustrious list member like O.R. Norton once
wrote in a private mail: "I am amazed that your picture came out so well
focused being hand held." Sometimes it takes several attempts with several
different camera settings before the result is what you expect.

Best wishes and good luck
when trying to take pictures
of your thin sections,

Bernd
