film solerization (not Sabattier)greenspun.com : LUSENET : B&W Photo - Film & Processing : One Thread
I was reading this old book from the seventies about film and it mentioned solarization, and says that true solarization is different form Sabattier effect, which is mistakely called solarization. Anyway, somebody else told me that solarization is extreme under exposure combined with extreme over development, which yields a crazy kind of transperancy. Can anybody explain solarization and give me some exposure and development times that I can use to start experimenting with.

If you can find a copy of the October issue of Shutterbug Magazine there is an artcle about solarization. If you follow the auther's instructions you can get some surprising effects.

There is also another phenomenon called solarization - extreme overexposure, when overexposured area became less dense. But I am not sure the book was about this.

True solarisation occurred with older films, where the characteristic curve dropped off after the shoulder. So if part of the subject gave that much exposure, the negative would be lighter (and the print, darker) than you would expect. From the word "solar" = "from the sun". There is an example in Ansel Adams, The Negative.
