Dark field microscopy (dark ground microscopy) describes microscopy methods, in both light and electron microscopy, which exclude the unscattered beam from the image. As a result, the field around the specimen (i.e. where there is no specimen to scatter the beam) is generally dark.

Confocal microscopy, most frequently confocal laser scanning microscopy (CLSM), is an optical imaging technique for increasing optical resolution and contrast of a micrograph by means of adding a spatial pinhole placed at the confocal plane of the lens to eliminate out-of-focus light. cited works: wikipedia
She is a bright, curious child who is a joy to have in class. For safety reasons, there are bright lights in the parking lot. Do you prefer pastels or bright colors?

The purpose of bright field microscopy is to provide a simple, yet effective, technique for use in observing microscopic properties of samples.
Phase-contrast microscopy is the observation of internal structures of living microbes where as bright field microscopy is the observation of killed stained specimens and naturally colored live ones.
