This is my first attempt at trying to get a decent photomicrograph of the inside of a geode. The geode is only about 6cm in diameter, and the image width represents a distance of about 6mm in the geode. The lighting is partially from the "front" and partially by strongly illuminating the back side of the geode. This image was a combination of nine images using Adobe CS4. The colors are difficult to adjust since the backlighting does give a very brown cast (the outside of the geode is the typical Indiana limestone brown). I obviously need to improve the "front" lighting, but have been having trouble getting the lamp system aligned for the Nikon Model M.
