Lenna (or Lena) is a standard test image used in the field of digital image processing starting in 1973,[1] but it is no longer considered appropriate by some authors.[2][3][4][5][6][7] It is a picture of the Swedish model Lena Forsén, shot by photographer Dwight Hooker, cropped from the centerfold of the November 1972 issue of Playboy magazine. The continued use of the image has attracted controversy, on both technical and social grounds, and many journals have discouraged or banned its use.[5][8][9][10] Forsén herself has said "It's time I retired from tech."[11]
The spelling "Lenna" came from the model's desire to encourage the proper pronunciation of her name. "I didn't want to be called Leena [English: /ˈliːnə/]," she explained.[12]

IPA pronunciation of Leena inserted into the quotation in brackets for clarity. /ˈliːnə/ is a common English pronunciation of the name Lena. The quotation reads, "At her suggestion, the editors [of Playboy] spelled her first name with an extra 'n,' to encourage proper pronunciation. 'I didn't want to be called Leena," she explained.'
