Latent Image - Reciprocity Law Failure

Reciprocity Law Failure

Reciprocity law failure is a phenomenon that same amount of exposure (irradiance multiplied by duration of exposure) produces different image density when the irradiance (and thus duration) is varied.

There are two kinds of reciprocity failure. They are both related to poor efficiency of utilizing photoelectrons to create latent image centers.

Famous quotes containing the words reciprocity, law and/or failure:

    Between women love is contemplative; caresses are intended less to gain possession of the other than gradually to re-create the self through her; separateness is abolished, there is no struggle, no victory, no defeat; in exact reciprocity each is at once subject and object, sovereign and slave; duality become mutuality.
    Simone De Beauvoir (1908–1986)

    A quality is something capable of being completely embodied. A law never can be embodied in its character as a law except by determining a habit. A quality is how something may or might have been. A law is how an endless future must continue to be.
    Charles Sanders Peirce (1839–1914)

    What we’ve got here is failure to communicate.
    Donn Pearce, U.S. screenwriter, Frank R. Pierson, and Stuart Rosenberg. Captain (Strother Martin)
