| A classical test object - the proboscis of a blowfly, a beautiful mount made by C M Topping. Looking through the eyepiece one can clearly see the spiracle-like structures in the radiating processes. This fine detail is lost in the digital image. Nonetheless some detail, such as the sensory hairs are captured quite well |

A dark-field shot. The head of an insect. The slide is labelled 'Picnis'. I am not sure what this is, but I suspect some sort of parasite. The original microscope came with only a concave mirror, but I felt the optics merited a proper condenser, so I fitted a minicondenser fabricated from a camera lens, which enabled this dgi shot. |

| Incident light? No problem! The toplight for this shot of foraminifera was supplied by a simple bracket holding a Mini-Maglite torch. Even at 640X480 quite a lot of the delicate tracery of the shells is visible in the original picture, but is lost in the reduction of the shot to its present size |

| Polarising shots are easy. Polaroid below the condenser, and a piece resting on the eyepiece. A piece of mica (1+ wave plate!) when interposed, provides some spectacular colours from a granitic rock section |

I Hope that these few shots from a low-cost (comparatively!) and low resolution digital camera will persuade you that a digital camera can be quite a useful accessory for the amateur microscopist.
Of course, by the time you read this megapixel cameras, capable of XGA, will be on sale at half the price I paid for my VGA camera, but such is the way of the electronics consumer industry!
