Bright Field:
In this mode the contrast formation is formed directly by absorption and scattering of electrons in the sample.
Thicker regions of the sample, or regions with a higher atomic number will appear dark, whereas regions with no sample in the beam path will appear bright – hence the term "bright field“.
Mass Thickness Contrast.
