Solarisations or Solarizations or Sabatier Effect Solarisations can

Solarisations (or Solarizations or Sabatier Effect) Solarisations can be done on film as well as on paper. In solarisation, not only are parts of the image reversed in tone but a thin line is generated around areas of contrasting tone, called a Mackie Line. If a film is treated the line is light, which produces a dark line in the print; when the print itself is processed it produces a white or light line around areas of high contrast. It is therefore always possible to determine whether a film or print has been used to produce the solarisation. A solarisation is alchemy. Basically, in a solarisation, the light sensitive material is RE-EXPOSED TO WHITE LIGHT DURING THE DEVELOPMENT STAGE of either film or paper processing. solarised film creates a very different effect from solarising the print. High contrast makes for a successful solarisation: high contrast subject matter (zebras, fishnets) high contrast lighting (sunny days, flash lighting) high contrast photographic materials (high numbered graded papers) All solarisations create an unnatural, often surreal effect.
