sfumato
Leonardo and Correggio both used the technique of a 'smoke-like haziness' as defined in Gardner's 'Art through the Ages'.
For instance the 'sfumato'. Dictionary definition:''sfumato n. The blurring or softening of sharp outlines in painting by subtle and gradual blending of one tone into another.''
Leonardo da Vinci is credited with being the first to use sfumato.
Leornardo Da Vinci used sfumato on his famous painting, the Mona Lisa. This allowed colors to shade gradually with each other making it impossible to tell if she is smiling or not, and if she has eyebrows.
