There are many fascinating video images of microbes, but depending on the microscopy techniques used, such as brightfield and darkfield, polarization, or phase contrast microscopy, they look quite different.

All of these techniques have specific advantages and disadvantages - they make some aspects of a microorganism look particularly good, while others tend to fade away. Of course, the question arises in view of all the different images - what does a microbe "really" look like now?
The following clip from the wonderful YouTube channel Journey to the Microcosm nicely explains how the different images are created by the different methods and why none depicts "reality". (via Kottke)
