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)
“No great idea in its beginning can ever be within the law. How can it be within the law? The law is stationary. The law is fixed. The law is a chariot wheel which binds us all regardless of conditions or place or time.”
—Emma Goldman (1869–1940)
“Any effort in philosophy to make the obscure obvious is likely to be unappealing, for the penalty of failure is confusion while the reward of success is banality. An answer, once found, is dull; and the only remaining interest lies in a further effort to render equally dull what is still obscure enough to be intriguing.”
—Nelson Goodman (b. 1906)
