Micrographs refer to photos that are taken up-close of something that is very small, such as cells or very small organisms. Synonyms for micrographs could include terms like photomicrograph, electron micrograph, and light micrograph. Each of these terms is used to describe images that are taken using different types of microscopes. For example, an electron micrograph is taken using an electron microscope, which provides more detail than a light microscope could. Similarly, a photomicrograph or light micrograph can be taken using a light microscope and can have some level of detail, but not as much as an electron micrograph. Overall, these synonyms all refer to different types of images that provide detailed views of very small items.
