Thanks again Freddy. The EXIF is intact, but these are very thin slices made with a razor blade. They are the width of a #2 pencil lead, without the wood. I used a Nikon Fluophot research microscope with a Canon T1i mounted on the trinocular port at the top of the scope. I made whats called an oblique lighting filter made from heavy black posterboard, that when placed above the condenser under the stage, allows only a thin slit of light through to the bottom of the slide, and from the side. Because the light is coming from a steep angle at the side, it would just go right on through the glass slide and not up through the objective lens. When the light does hit something, in this case, the slice of stalk, it is then bounced up into the lens and then up the tube to my camera. It's an elegant invention and you see the results. It has the effect of turning anything in the background black.
This was taken with a 10x objective lens, then through a 2.5x projector lens, then up through two sets of Kenko tubes and into the camera sensor. It works out roughly to 100 power or so. 
PP is just convert from RAW in CS5, then a little bit of levels and convert to TIFF to resize for the forum and sharpen a little bit, then converted to jpg.
