==''Mona Lisa'' illusion==
If a person being photographed looks into the camera lens, the image produced provides an illusion that viewers perceive as the subject looking at them, irrespective of the photograph's position. It is presumably for this reason that many people, while taking photographs, ask subjects to look at the camera rather than anywhere else. In psychology, this is known as the "''Mona Lisa'' illusion", which was named after the famous painting that also presents the same illusion.<ref name="Horstmann_2019">{{cite journal |vauthors=Horstmann G, Loth S |title=The Mona Lisa Illusion-Scientists See Her Looking at Them Though She Isn't |journal=Iperception |volume=10 |issue=1 |pages= |date=2019 |doi=10.1177/2041669518821702 |url= |pmid=30671222 |pmc=6327345}}</ref>
