Pseudo-solarization is a phenomenon in [[photography]] in which the image recorded on a [[Negative (photography)|negative]] or on a photographic print is wholly or partially reversed in tone. Dark areas appear light or/and light areas appear dark. Solarisation and pseudo-solarisation are quite distinct effects.

The term solarization in photography is used to describe the effect observed in cases of extreme overexposure of the negative in the camera. Most likely, the effect was first observed in scenery photographs including the sun (e.q. sol, sun). The sun, instead of being the whitest spot in the image, turned black or grey. Minor White's photograph of a winter scene, The Black Sun 1955,[1] was a result of the shutter of his camera freezing in the open position, resulting in partial overexposure.[2] Ansel Adams created an image titled Black Sun, Owens Valley, California (1939) by overexposure solarization.[3][4]
The solarization effect was already known to Daguerre[citation needed] and is one of the earliest known effects in photography. John William Draper was the first to call the overexposure effect solarisation[citation needed]. J.W.F. Herschel already observed the reversal of the image from negative to positive by extreme overexposure in 1840[citation needed]. The first time the solarization effect was observed (without knowing what it was) was by N.M.P. Lerebours in 1842 when he made a daguerreotype of an image of the sun. The result was seen as unsatisfactorily because the solar disk (image of the sun on the daguerreotype plate) was overexposed and solarized.[5]L. Moser reported in 1843: "...that the light in the camera obscura produces at first the well known negative image; with continued action of the light the image turns into a positive image.... and recently I have obtained in fact on occasion a third image which is negative".[6] In 1880 Janssen had obtained in the strongest sunlight a repetition of the solarization phenomena.[7][8]
Pseudo-solarization
Pseudo-solarization is a phenomenon in photography in which the image recorded on a negative or on a photographic print is wholly or partially reversed in tone. Dark areas appear light or/and light areas appear dark. Solarisation and pseudo-solarisation are quite distinct effects. In many amateur darkroom publications the term "pseudo-solarisation" has been shortened to "solarisation".[9]
