What is the difference between a bright field and dark field image?

The most common sources of image contrast are particle mass and crystallinity. Heavier atoms scatter electrons more intensely than lighter atoms. Hence, in bright field mode, the regions with heavier atoms are darker, while in dark field mode these regions are brighter.

What is the difference between bright field and dark field microscope?

Specimens which are transparent are often stained and observed under a bright field microscope. Specimens which absorb little or no light are kept unstained and observed under a dark field microscope.

What is the difference between light field and dark field?

Unlike in bright field lighting, where reflected light is imaged, dark field lighting only captures scattered light. By imaging only the scattered light, edges and surface defects become more prominent in the image as they are the things that best scatter light.

What is a bright field image?

The most common is known as brightfield imaging, where images are produced by uniformly illuminating the entire sample so that the specimen appears as a dark image against a brightly lit background. Brightfield imaging is used as a general imaging technique for observation and inspection of samples.
