A bright field microscope is the basic compound microscope that most people are familiar with, for viewing transparent/translucent specimens by white light passing through them from below. The same instrument could be modified for other types of viewing such as dark field or phase contrast, but brightfield is the "default" setting of any ordinary light microscope.

A brightfield illumination microscope is one where the light source is on the opposite side of the specimen stage from the objective lenses and there are no modifications made to the light as it passes through the sample, it is essentially white light with no treatment. This type of microscopy is useful for examining specimens that have naturally occurring coloration or for specimens that have been stained with dyes or pigments to retain a color or series of colors, such as staining tissues with hematoxylin and eosin.

It's a variety of electron microscope in which the electrons are used to create a shadow of what you're looking at on a "bright field" i.e. a light colored stage

Bright field microscopy is best suited to viewing stained or naturally pigmented specimens such as stained prepared slides of tissue sections or living photosynthetic organisms. It is useless for living specimens of bacteria, and inferior for non-photosynthetic protists or metazoans, or unstained cell suspensions or tissue sections

Even more confusing - why would you take the time to shift/unshift constantly?
