Step 11: Take Some Test Shots
My Canon S50 has 3X optical zoom. Zoom all the way out to your camera's max OPTICAL zoom (don't bother with digital zoom, it won't help) to minimize vignetting (that's the black outer circle you see through microscopes.)
With such a high magnification, there is a serious shake issue. Either put your camera on a tripod or set it on a table. Now, scoot the object up to the lens until it is in focus. In my set up, the object needs to be within 5mm of the glass surface of the lens.
Or, if you like a challenge, try to hold it in your hands. You will need LOTS of light. White LED booklights and flashlights work reasonably well.
