Nice looking flakes, but it is not much below freezing, so hard to keep then intact to put them under the microscope.? They survive OK, but the light from the scope takes its toll.? It is an overhead LED, but light is still light, and black is still black and absorbs light and heats up.? With only 2 degrees F leeway, it is not enough.? Will have to hope for more snow when it gets colder. Here are are a few first attempts.? I had to change background materials as the one I bought was too fibery and you could hardly see the flakes for the fibers.? These are just black matte board, all I could find that was handy. This one is not too bad as it was setting a bit above the surface of the board, so not too distracting. _DSC2588 (leica-users.org) <http://gallery.leica-users.org/v/Aram/w22_001/s/_DSC2588.jpg.html> This one shows the board texture and you can see where the flake is melting already. _DSC2598-Edit (leica-users.org) <http://gallery.leica-users.org/v/Aram/w22_001/s/_DSC2598-Edit.jpg.html> And this one had melted almost flat on the board so no real separation.? The texture of the board is very evident, but still way better than the felt I had originally thought to use. _DSC2590-Edit (leica-users.org) <http://gallery.leica-users.org/v/Aram/w22_001/s/_DSC2590-Edit.jpg.html> I am thinking I will take some microscope slides, freeze them, then put them on the matte board.? They should hold the flakes far enough away from the board surface that the texture might not show up. These are all stacked images of 3-5 images for DOF. Comments and suggestions welcome.
