Editing Scanning electron microscope (section)

===SEM image coloring===
Very often, published SEM images are artificially colored.<ref name="Mignot-2018"/> This may be done for aesthetic effect, to clarify structure or to add a realistic appearance to the sample and generally does not add information about the specimen.<ref>{{cite web|title=Introduction to Electron Microscopy|url=http://www.fei.com/uploadedfiles/documents/content/introduction_to_em_booklet_july_10.pdf|publisher=FEI Company|access-date=12 December 2012|page=15}}</ref>

Coloring may be performed manually with photo-editing software, or semi-automatically with dedicated software using feature-detection or object-oriented segmentation.<ref>{{cite web|title=Next Monday, Digital Surf to Launch Revolutionary SEM Image Colorization|url=http://www.azom.com/news.aspx?newsID=45031|publisher=AZO Materials|access-date=23 January 2016|date=2016-01-22}}</ref>
